Latest news

Given the advancements in medical technology and the high success ratio of corrective eye surgeries, PRK and LASIK have become the most popular vision correction procedures in the recent times. While both these surgeries have the ability to improve vision dramatically, the procedures vary widely in how they are performed. If you are considering a minimally invasive corrective surgery to get rid of vision problems, it is important that you know if you are the right candidate for PRK or LASIK and make an informed choice.

To help you know your treatment options better, we have come up with an easy-to-follow infographic that lists everything right from the eligibility criteria and the pre-operative instructions to the surgical procedure and post-operative care. Quickly browse through this infographic and make a choice that is in the best of your interest.

PRK vs LASIK

Definition

Extracapsular cataract extraction (ECCE) is a type of eye surgery in which the lens of the eyes are removed, leaving the elastic capsule covering the lens which is left partially attached to allow the implantation of an intraocular lens (IOL).

Purpose

The main purpose of ECCE is to restore clear vision by removing the clouded and discolored lens and replacing it with an IOL. Cataract operations are some of the oldest recorded surgical processes dating back to 1750 B.C.

It is a cataract surgery that involves removing the eye’s natural lens while leaving the back of the capsule which holds the lens in place. This process requires a much smaller incision as compared to the older process called Intracapsular Cataract Extraction. A modified version of Extracapsular Cataract Extraction is called Phacoemulsification and uses an even smaller incision which requires no sutures at all.

The natural lens become cloudy, usually due to the aging process. This cloudy lens is called a cataract. The main objective of modern cataract surgery is to remove this hazy lens and replace it with a tiny plastic prescription lens that will be permanently implanted in your eye.

Extracapsular Cataract Extraction

Extracapsular Cataract Extraction is a method of cataract surgery that involves removing the eye’s natural lenses while leaving the back of the capsule that holds the lens in place. This procedure requires a much smaller incision than the older process called Intracapsular Cataract Extraction in which the lens and the entire capsule were removed.

In this procedure, the surgeon makes a tiny incision in the white of the eye near the outer edges of the cornea. The size of this depends on whether the lens of the nucleus is to be removed all in one piece or whether it will be dissolved into tiny pieces and then vacuumed out. The surgeon then enters the eye through this incision and carefully opens the front of the capsule that holds the lens in place. After the nucleus or hard center is removed, you may need sutures if your cataract was removed in one piece. If the phacoemulsification technique is employed, sutures are usually not required to close the incision.

Demographics

  • Cataract extraction is one of the most frequently performed surgical procedures in industrialized countries. Around 300,000-400,000 cases of disabling cataracts occur annually in the USA alone. 1 to 1.5 million cataract extractions are performed annually in the United States.
  • Estimates by the WHO in 1997 state that cataracts are responsible for 50% of the cases of blindness globally. This figure is expected to rise to 50 million by 2020. 1.2% of the population in Africa is blind of which cataracts are responsible for 36% of such cases.
  • About one person in every 50 of the American population will eventually have to have a cataract removed. Rates of cataract formation varies from group to group though. 50% of people over the age of 60 have some degree of cataract formation, with the figure rising to 100% for those aged 80 and above.

Risk Factors that Come with Age

  • Genetic Factors
  • Sex
    Women are a bit more likely to develop cataracts over time.
  • Exposure to Ultra-Violet Rays
    Cortical cataracts are more likely to occur to people who are exposed to sunlight frequently.
  • Smoking
    People who smoke more than 25 cigarettes a day are more likely to develop nuclear or PSC cataracts.
  • Heavy Alcohol Consumption
  • Use of Steroid Medication
  • Socioeconomic Status
    People with college education have lower rates of cataract formation than people who did not finish school.
  • Chronic dehydration, Diarrhea and Malnutrition.

lasik eye surgery

There are different types of refractive surgeries that improve eyesight problems and eliminate dependence on visual aids. Laser Assisted In Situ Keratomileusis (LASIK) is one solution that has become quite popular because of the many benefits it offers.

What is LASIK and What Are It’s Benefits?

LASIK is a laser operation that uses ‘excimer’ UV rays to alter the shape of the cornea. This corrects any errors that cause visual impairment, when light does not focus accurately on the retina.

Data collected by research firm Market Scope estimated that over 600,000 LASIK procedures were performed throughout the USA in 2011 alone. Why, then, is there such a high patient count for a procedure that has been around since 1991?

The answer lies in the benefits that patients enjoy. Here’s why LASIK surgery is a good treatment choice for those who qualify for it:

  1. Lasting Solution and Quick Vision Correction – Sight improvement after a LASIK procedure is, in most cases, permanent. Sometimes, blurry vision can reoccur, in which case patients have to follow up with LASIK enhancement to restore their vision. However, the American Academy of Ophthalmology reports that LASIK surgery has a success rate of up to 90%, with most patients recovering anywhere between 20/20 and
    20/40 vision. As it is a laser procedure, it is quick and almost painless. This is hugely beneficial and convenient for the patient. The surgery only takes around 10 to 30 minutes.
  2. Low-Cost Procedure and Saves Money – Compared to other refractive procedures, LASIK surgery is more affordable. The average cost ranges between $1,700 and $4,000 per eye, depending on your chosen eye care center, geographical location, your vision problem, etc. Many eye clinics also provide flexible financing methods (medical insurance, monthly installments, credit card payments, etc.). Since the results of this surgery last for years to come and may also last a lifetime. This saves you a lot of money as you no longer need to invest heavily in eyeglasses or contact lenses.
  3. Fast Recovery and Minimal PainYour eye surgeon will make a small incision on the cornea, to create a flap of tissue that will be lifted during the surgery. Since the laser correction surgery is minimally invasive, recovery times tend to be fast. Some patients report improvements within a day or two, and most recover full vision function within a week. Contrary to the belief, this procedure is minimally invasive and hence is almost painless.
  4. Natural Facial Attributes – An added bonus of this procedure is that it allows you to maintain your natural facial look. After prolonged periods of wearing prescription glasses, the eyes eventually look smaller or larger, since corrective lenses increase the eyes’ axial length (the retina continually adjusts backward or forward for clearer vision).
  5. Ability to take part in different activities – Professional activities such as acting,
    athletics, defense etc., require correct vision. LASIK provides safe, reliable, quick, long lasting results and a near perfect vision. This allows the person to take up different activities which require correct vision.
  6. Reduced Risks of Allergies and Infections – Many patients who underwent LASIK have shared cases of reduced allergy symptoms. These include reduction in sinus due to lack of pain resulting from glasses sitting on the nose, lesser headaches and lack of irritation and redness in the eye due to constant use of contact lenses.
  7. Better Quality of Life – By eliminating visual aids, LASIK provides many other benefits. For instance, there will be less eye irritation, redness or allergic reactions caused by contact lenses. What’s more, not having to wear glasses will:
    • Eliminate sinus pain caused by the bridge of prescription glasses pressing on your nose
    • Get rid of headaches caused by the muscles in your eyes becoming overworked by corrective lenses
    • Improve side vision, which is usually blocked by the frame of eye glasses
    • Reduce glare from lenses that causes poor night time vision

Who Makes a Good Candidate?

LASIK is often recommended to patients who suffer from hyperopia (farsightedness) myopia (shortsightedness) or astigmatism (a vision defect associated with distorted or blurry images).

It can also correct vision problems caused by glaucoma disease, but only if there is no damage to the optic nerve and intraocular pressure remains normal when wearing contacts or eyeglasses. A vision test will determine the severity of glaucoma symptoms and determine whether this refractive surgery is a viable treatment option or not.

Patients with dry eyes or thin corneas may not qualify for this procedure, and it cannot restore cataract-triggered vision loss. If you’re unqualified for Lasik surgery, an ophthalmologist can suggest alternative refractive or laser technology procedures like PRK, which offer similar results.

Is LASIK Safe?

Like any surgical procedure, LASIK has risks. For instance, migrations of the corneal flap can cause complications such as inflammation, infections or even excess lacerations. There is also a possibility of developing dry eyes, double vision or haloes (mild glare) in the eye.

In rare cases, vision clarity may even deteriorate further, especially when patients miss follow-ups or fail to abide by post-operative care instructions. Some patients may be more predisposed to complications than others, in which case other alternative treatment options should be considered.

A professional consultation will help determine if you meet the medical requirements for a LASIK procedure. Contact the specialists at Insight Vision Center today!

A lot of treatments today are designed to lower or control intraocular pressure (IOP), which may damage the optic nerve that transfers visual information to your brain.

Glaucoma eye drops are usually the first option over glaucoma surgery which may be quite effective at controlling IOP to prevent eye damage. If you are an eligible candidate for glaucoma eye drops, you may be prescribed more than one type to achieve the best IOP control.

However, you may not be eligible due to your specific individual health condition. Because any medication placed in the eye is absorbed into the conjunctival blood vessels on the eye’s surface. A small amount is bound to enter the bloodstream and adversely affect your heart rate and breathing.

Certain types of eye drops may worsen certain medical conditions of yours such as asthma, and certain glaucoma medicines may also interact with other common medications such as asthma.

Some experimental glaucoma medications explore new ways of controlling IOP, other treatments are intended to protect the optic nerve (neuroprotection) to prevent eye damage, potential vision loss or even blindness.

How Beta Blockers Work

Beta Blockers decrease the pressure inside your eyes by reducing how much fluid (aqueous humor) is produced in the eyes. Reducing pressure in the eyes, slows down optic nerve damage which greatly decreases the rate of vision loss.

Types of Beta Blockers

There are two classes of Beta Blockers which are non-selective and selective:

These are the 5 Non-Selective Beta Blockers:
  1. Levobunolol(Betagan)
  2. Timolol Hemihydrate (Betimol)
  3. Carteolol (Ocupress)
  4. Metipranolol (Optipranolol)
  5. Timolol Maleate (Timoptic) and Timolol Maleate Gel (Timoptic XE)

All of the above are used alone or with other prescribed medication to treat high pressure inside the eye due to glaucoma or other eye diseases. Lowering the high pressure inside the eyes helps prevent blindness.

Selective Beta Blockers

  • Betaxolol
    This is the only selective Beta Blocker that is used to treat high blood pressure. It has a better safety profile as compared to the non-selective Beta Blockers, particularly in terms of breathing symptoms. The eye pressure lowering effect is also slightly less with selective beta blockers.

Beta Blocker Medications/ Treatment

  • Alpha-Adrenergic Agonists

    This medication works by decreasing the rate of aqueous humor production and may be used alone, or other anti-glaucoma eye drops. FDA-approved medications at this level include Lopidine, Alphagan, and Alphagan-P.

  • Carbonic Anhydrase Inhibitors

    This medication works by reducing the rate of aqueous humor production. They are mostly used in combination with other anti-glaucoma and not alone. This drug is also used in oral form. FDA approved eye drops in this category include Trusopt and Azopt.

  • Parasympathomimetics

    This medication works by increasing the outflow of aqueous humor from the eye. Mostly used to control the IOP in narrow-angle glaucoma. These type of eye drops cause your pupils to constrict, which assists in opening the narrowed or blocked angles where drainage occurs.

  • Epinephrine

    This type of drug has a dual effect on your eye and work by decreasing the rate of aqueous humor production and increasing the outflow of aqueous humor from the eye.

  • Hyperosmotic Agents

    This drug is usually for people with a severely high IOP that must be reduced immediately before permanent; irreversible damage occurs to your optic nerve. For this reason alone, some ophthalmic pharmaceutical companies have produced “combination” eye drops that can include different anti-glaucoma medicines in the same bottle.

Side Effects of Beta Blockers

Most medicines have side effects so just to be clear, ask your pharmacist about the side effects of each medicine you consume. But mostly the benefits of the medicine are a lot more important than any minor side effects.

  • Stinging, aching, or redness in the eyes after using any eye drops
  • A slower heartbeat
  • Headaches
  • Feel tired, dizzy, off-balance, confused or depressed.

sports eye injury

Sports are fun, but they can also expose players to eye injuries, some of which result in impaired eye vision or even irreversible blindness. According to the American Academy of Ophthalmology, each year sees over 40,000 cases of sports-related eye injuries!

Although the statistics seem grim, there is hope. Prevent Blindness America, a leading volunteer eye health and safety organization, reports that 90% of all reported eye injuries in sports can be prevented if you take the necessary precautions and use protective eyewear.

Which Sports Can Cause Eye Injury?

Sports that expose players to eye injury are usually classified into 3 groups:

  • Low risk sports involve zero bodily contact and no flying or swinging tools (like balls, pucks, bats, and rackets). E.g. car racing, track/field running, cycling, gymnastics, and swimming.
  • High-risk sports (or collision sports), involve flying objects and a significant amount of body contact between players. E.g. lacrosse, tennis, baseball, football, and basketball.
  • Very high-risk sports that involve extensive body contact and players often aren’t allowed to use protective eyewear, increasing maximum exposure to possible eye injuries in sports like wrestling, MMA, boxing, etc.

Types of Sports-Related Eye Injuries

  • Abrasions: Medically referred to as a corneal abrasion, this is the least serious form of sports-related eye injury. It usually occurs when something sharp (e.g. fingernail or fencing sword) scrapes the outer surface of the eye, which is usually quite painful.
  • Eye Trauma: This is the most common injury type and occurs when something (fist, ball, knee, etc.) hits the eye with significant force. Eye trauma can cause mild (e.g. bruise) or severe (e.g. retinal bleeding) damage, depending on size, hardness, and velocity of the object hitting the eye.
  • Penetrating Injuries: These are the most serious eye injuries, almost always resulting in sight-threatening damage. They occur when foreign objects (e.g. BB pellets, pieces of eyeglasses) hit and pierce the eye.
  • Radiation Injuries: Caused by over-exposure to UV rays, these are quite rare and only occur with snow- and water-related activities.
  • Orbital Fracture:: Usually caused by a blunt force that breaks the bone surrounding the eyeball, the orbital fracture can also include optic nerve damage and facial trauma.

Depending on the severity of eye injuries in sports, certain cases can also result in permanent blindness. Any type of vision impairment will not only keep you out of the game for months but also affect your day-to-day life. This is why the importance of protective eyewear cannot be understated. Eye protection gear is easily available for all mainstream games including football, cricket, basketball, racquetball, lacrosse, skiing, golf as well as water polo.

Safety glasses not only ensure eye protection against foreign matter and flying balls but also keep the risk of impaired eye vision at bay.

Common Eye Injury Symptoms

  • Pain and/or bruising over affected eye
  • Blurred vision or visual loss
  • External or internal hemorrhage
  • The feeling of a foreign body within the eye

Preventive Tips and Precautions

  • Wear protective eyewear with cushioning along the eyebrows and polycarbonate lenses (that are powerful enough to protect against a .22 caliber bullet).
  • Being extra careful when engaging in sports that involve sharp or flying objects.
  • Wearing helmets and other face shields when appropriate.
  • Perfecting your dodging skills!
  • Get professional helps when picking your eye protection gear to ensure you are wearing relevant eye guards or goggles that shield your eyes against harmful UV rays.

Returning to Sports after an Eye Injury

Only an ophthalmologist can accurately predict how long an injured eye will take to fully heal, after conducting a thorough eye checkup. This is why it’s crucial to visit an eye doctor immediately after sustaining a sports-triggered eye injury.

Why Athletes Should Consider LASIK

Visually impaired athletes are at a great disadvantage. Their vision is less than a 100%, but corrective visual aids don’t help. Contact lenses get easily irritated by dirt or sweat, while eyeglasses can shatter while playing, and possibly even pierce the eyes. The best solution is LASIK (Laser Assisted In Situ Keratomileusis) surgery.

This special form of laser operation corrects a number of eye problems. With successful LASIK surgery and full recovery (usually at least 2 weeks), a visually impaired athlete will be able to play without wearing contact lenses or glasses. Tiger Woods, Greg Maddux, and LeBron James are some famous athletes who have enjoyed the benefits of LASIK.

Other than wearing a faceguard or protective eyewear that will bear the brunt of any impact during a game, visiting an eye care center for LASIK surgery could be your smartest move. At Insight Vision Center, we have an experienced eye care team that specializes in eye injury treatment and can efficiently address all your vision related issues. So, if you are ever faced with an eye injury, book an emergency appointment with us and keep your vision intact.

using eyeglasses for children

Your kid has made a successful visit to an eye doctor without causing any problem and has come out with a prescription for glasses. But the challenging part may begin now if he/she refuses to wear the glasses. The following suggestions will help you get the kids acclimatized with their new glasses.

Important Tips

  • Ensure The Glasses Have A Perfect Fit

    The frame should not pinch the ears or nose of your child. A well-fitting frame sits comfortably without leaving any pressure marks on the nose-bridge or ears. Check regularly if there is any skin irritation – change the frame if any signs of irritation show up. Most frames for infants and young kids are made of rubber-like materials for comfort. They also have bands that wrap around the head which prevents constant falling of the glasses, and also makes it difficult for kids to remove them frequently.

  • Check If The Prescription Is Correct

    If you child complaints that he/she can’t see clearly even with glasses or if they constantly look over the glasses, then chances are that the prescription is incorrect. Visit an eye doctor to get the accuracy of prescription rectified.

  • Take Baby Steps

    Young children may find glasses very obtrusive when they first start using them and may start coming up with excuses not to use them. Don’t force it upon them – rather tell them to start wearing it for a few hours every day. Gradually increase their wearing time to full day. This gradual transition will allow them to get accustomed to glasses and, before they know it, they will be start wearing it regularly.

  • Make It A Routine

    Developing a routine around the glasses will be beneficial for the children. Encourage them to put on the glasses after waking up and take them off only while sleeping or bathing. It might take some time but once they get into a daily routine, it’ll come easily and naturally for them to use glasses on a daily basis.

  • Practice Positive Reinforcement

    Letting the kids know that they look good in glasses will encourage them to wear the glasses. Treat them with a present for wearing the new glasses. Praise them every day, till they get comfortable, as positive reinforcements go a long way in convincing them to wear glasses regularly.

What If My Child Refuses To Wear Glasses

It’s normal for a child to resist wearing glasses when they are new for them. However, don’t let their resistance and annoyance make you lenient. Ensure that the prescription is correct and then gently explain why it’s important for them to wear glasses regularly. Positive reinforcement usually works. Be persistent and eventually the kids will start wearing them regularly.

Precautions to Take While Playing Sports

Children are prone to dozen of eye injuries on the sports fields and courts when they play without protecting their eyes. Protective eye-gear come in prescription and non-prescription lenses. If your kid participates in any of the following sport, make sport goggles a must in their sporting kit.

  • Baseball/softball
  • Soccer
  • Hockey
  • Basketball
  • Swimming
  • Tennis/racquetball
  • Karate/martial arts

Children may hesitate to wear protective lenses if they are the only ones using the glasses in their team. Convince them to put on their glasses nevertheless. Allowing kids to choose their own eyewear will persuade them to wear the glasses.

If your child can’t see distant or nearby objects clearly, make a visit to an eye doctor or an optician to get their vision checked. Once prescribed, make sure they diligently use the eye glasses to prevent further damage to the vision.

children's eye safety month

August is the global Children’s Eye Health and Safety Month – a perfect reminder for you to have your children’s eyes checked.

Give your children the best opportunities to develop the best possible vision they can, which is why regular vision checks are of absolute importance.

All children’s eyes are mostly healthy, but you should have them examined during scheduled pediatric visits which should ideally start from the age of three onwards.

Symptoms of Eye and Vision Problems in Children

You as parents should be aware of all the signs that indicate whether your child has any vision-related problems such as these:

  • Wandering or crossed eyes
  • A family history of childhood vision related problems
  • Lack of interest in reading or looking at distant objects
  • Squinting or turning his/her head unusually while watching television
  • Eyes are constantly watering or tearing
  • The eyelids are swollen or bloodshot
  • The child is blinking more than usual
  • Child is complaining of blurry vision; eyes are itchy or burning
  • Feel dizzy or ill after doing some close-up vision related activity

Protect Your Child’s Eyes

We should all utilize this month to teach our children about the importance of eye safety and also implement it with immediate effect.

You can protect your child’s eyes by:

  • Making it mandatory for your kids to wear protective eyewear while taking part in any sports or recreational events.
  • Allowing them to play with toys that have no sharp or protruding edges or corners.

The Role of Eye Safety in Your Child’s Life

Now that you have done everything that you possibly can to ensure that your child’s eyes are safe. Whether they are budding sportsmen or simply just playing with their friends, there are a lot of injuries that they are exposed to. According to current stats, roughly more than 12 million children suffer from some kind of vision impairment and eye injuries which are often the cause of eye injuries, of which 42,000 sports-related eye injuries.

Take precautions and protect your children’s vision. This August, give the apple of your eye the gift of clear vision. Be a Super Mom and bring your child to InSight Vision Center for a comprehensive eye checkup.

carrots improve eyesight

One of the most common tricks that parents use to encourage or trick their kids to eat vegetables is to amplify the ‘good’ a particular vegetable can provide. The common ones include eating spinach for strength, broccoli to make you smarter, drinking milk will make you taller etc. But one of the oldest and the most popular saying remains – ‘Eat carrots to get excellent eyesight’. Tricking younger kids may be simpler but there may come a time when they will start questioning the authenticity of such claims.

Let us delve into the history to see of how this adage came into existence and became one of the most used statements by parents across the world.

The History

Bugs bunny’s favorite food became associated with strong eyesight during World War II when the British Royal Air Force managed to gun down German aircrafts even at nights. The air force fabricated a story of how their skilled fighter pilot John “Cats’ eyes” Cunningham attributed his excellent night vision due to a carrot-enriched diet. Soon, everyone began to eat more carrots get stronger night vision so that they could work in the dark as well. However, it turned out to be mere propaganda as the Air Force was, in fact, utilizing radar to locate the German bombers.

Why Should You incorporate Carrots in Your Diet

Even though it started as a myth, having carrots do help in maintaining healthy eyes due to the presence of the following nutrients:

Vitamin A

It is extremely essential for healthy eyes. Carrots are rich in beta-carotene, a carotenoid pigment which is an essential precursor for vitamin A. If you don’t get enough Vitamin A, you risk getting cataracts, macular degeneration and xerophthalmia (A disease characterized by dry eyes, corneal ulcers and swollen eye lids). Deficiency in vitamin A also leads to blindness.

Lutein

This is an important antioxidant which is present in carrots. Food products that are rich in lutein are known to increase the pigment density in the macula. When the pigment density increases, the retina is protected more, thus reducing the risk for macular degeneration.

How Many Carrots is too Many Carrots

Even though carrots are rich in nutrients, binging on them won’t improve your eyesight significantly. Once there is enough beta-carotene in your body, it will no longer convert to vitamin A. In fact, it’ll regulate the excess vitamin A to prevent accumulation of toxic levels of the substance in the body. Though there is no ‘ideal number’ of carrots one should consume, it can safely be said that having a moderate amount in your daily diet will be helpful. Most eye and vision problems are either genetic, due to aging, disease or an accident. Just eating carrots and infusing beta-carotene and lutein will not help in such situation. The right medication and eye treatment are essential.

We can safely say that eating carrots every day will not sharpen your eyesight beyond a certain measure and will definitely not restore the vision to 20/20, nor can it correct certain optical deformities such as astigmatism, diseases like glaucoma and conditions like strabismus. If you have weak eyesight, using prescribed glasses or contact lenses is recommended. That definitely doesn’t mean that carrots don’t make a healthy snack – eat it to satiate those hunger pangs between meals and pack it in the lunches for your kids. But don’t let them believe that they can ditch their glasses just because they will get superman-like vision just by eating carrots.

When you parents and grandparents told you to eat carrots for good vision, they weren’t entirely wrong. But if you are facing vision problems, visit a doctor instead of just relying on a carrot-rich diet.

laser skin surfacing

Laser Skin Resurfacing, also known as a laser peel, laser vaporization and lasabrasion is a technique to use laser beams to reduce facial wrinkles, scars and blemishes. With laser technology, surgeons have a higher level of control and precision around the delicate areas, thus offering better results.

What is Skin Laser Resurfacing

It’s a popular cosmetic procedure that helps in rejuvenating the skin through laser technology. Along with facial scars, wrinkles and blemishes, it reduces the effects of aging, sun and some facial disorders. It removes the outer, damaged skin and gives way to a smoother, younger, healthier-looking skin.

How Does It Work

The surgeon uses laser to send short, concentrated pulsating beams of light at irregular skin. The laser beam removes the epidermis (the outer layer of the skin), and simultaneously heats the underlying skin, which is called the dermis. This stimulates the growth of new collagen fibers. After the treated area heals completely, firm and smoother skin is formed.

Ideal Laser Skin Resurfacing Candidates

The ideal candidate for this procedure is someone with an elastic, non-oily skin that isn’t prone to scarring after minor injury. Patients with wrinkles, lines and uneven pigmentation can opt for laser skin resurfacing. Those with superficial facial scars such as acne or chickenpox scarring, birthmarks, enlarged oil glands etc. can also consider undergoing this procedure. It is crucial that the person is free of any medical conditions, including prescription medication and existing health conditions which may cause unnecessary risk during the treatment or recovery period. Before going in for the procedure, the candidate should have realistic expectations of the results.

The Procedure

A local anesthesia is administered through an injection at the treatment site. If necessary, an oral sedative may also be used. Once the anesthesia is under effect, the surgeon will use a special laser to carry out the procedure. A controlled, pulsated beam of light is given which vaporizes the epidermis and reveals the younger-looking skin that lies underneath. The growth of new skin cells is also stimulated.

The full procedure can take up to 2 hours while a partial procedure doesn’t last longer than 30 to 45 minutes. A concentrated laser beam minimizes the complications by restricting the amount of heat damage done to the skin.

The Benefits of Laser Skin Resurfacing

  • Improves the overall texture of the skin that has become rough due to sun damage
  • Enhances the youthfulness of the skin
  • Diminishes the appearance of age spots, wrinkles, skin discoloration, birthmarks etc.
  • Removes skin growths such as moles, warts
  • Can be used for treating skin cancer in earliest stages
  • Moderate facial scarring results from injury or surgery can be minimized

Risks Involved

  • Bacterial infection or abnormal healing
  • Reactivating herpes cold sores
  • Hyperpigmentation or Hypopigmentation
  • Scarring or burns from laser’s heat
  • Smoking increases the duration of recovery period

Inform your doctor if you have any medical conditions, drug allergies or immune disorders before the procedure. This helps them in preparing better for the surgery and administering the right medication for your recovery without any threat of risks.

Expected Recovery Time & Results

The recovery period lasts around two weeks. During this time, the treated skin will heal and a new layer of skin will appear. However, the redness of the skin might persist for several months. Depending on the extent of the treatment, patients should take a break of one to two weeks from work immediately after the procedure.

Human Eye vs Eagle Eye

Eagles are beautiful birds known for their majestic frame and incredible hunting abilities. They have the reputation of having one of the best visions on the planet. What makes ‘eagle eyes’ a thing of envy? Let’s find out.

Visual Acuity

Visual acuity is the eye’s ability to separate details of an object without any blur. The normal or a ‘good’ vision for a human is 20/20. Eagles, however, have retinas with cones and have a much deeper fovea—a cone-rich structure in the back of the eye. These give them a visual acuity of an impressive 20/5, or 20/4 which allows them to hunt even the tiny prey from hundreds of feet up in the air.

How Is the Eagle’s Vision Measured

There is a scientific set-up to determine the strength of eagle’s vision. The birds are trained to fly down a long tunnel where two TV screens are kept at the end. One screen has a display of striped pattern to attract the eagle towards it and when they land on that screen, they are given a treat. The birds’ acuity is tested by changing the width of the stripes and determining from what distance the eagles begin to turn in the correct direction.

The Range and Vividness of Colors

Eagles have the ability to see colors more vividly than humans can. They can even see ultraviolet light and pick out more shades of one color. Their ability to even see the UV light allows them to see the bodily traces left by their prey. Mice’s and other small prey’s urine is visible to the eagles in the ultraviolent range, making them easy targets even a few hundred feet above the ground.

Positioning of the Eyes

Human eyes are positioned at the front of the heads, giving us a binocular vision and a peripheral vision of just 180 degrees. We can only see complete images when we use both eyes, as closing one will block a portion of vision that was visible with that eye. The use of both eyes gives us that ability to determine the depth of field and help us realize the speed of any moving object. Unfortunately, our peripheral vision is quite poor.

On the other hand, an eagle’s eyes are rotated towards the front of the head and are angled 30 degrees from the midline of the face. This allows them to have a 340 degree field of vision. Their peripheral vision is quite impressive, which greatly assists these predatory birds.

Ability to Focus Clearly

The ability to switch between seeing things that are near and far clearly require quick changes in the lens of the eyes, which is known as accommodation. As humans age, the muscles required to change the shape of the lens get stiff and become less effective, requiring us to wear glasses to see distant and nearby things equally clear. However, the eagles not only have a lens that changes the shape to accommodate the changing distance but even their cornea has the ability to change shape to better focus on near and far objects.

Can We Get Eagle Eyes

It is obvious to want vision like an eagle but the characteristics and dimensions of human eye’s lens, cornea, iris, retina etc. limits our visual acuity. The best vision we can achieve is 20/10 or even 20/8. LASIK can help you in getting 20/20 vision even if you have poor vision, but achieving the visual acuity of an eagle is next to impossible.

While attaining eagle eyes will remain a fantasy for us, you can improve your eye sight through LASIK. Visit InSight Vision Center and make an appointment today to explore your options.
