Are You a Good Candidate for LASIK Surgery

eye exam

Excited about finally ditching your glasses and contact lenses to get LASIK surgery? However, before you enjoy the benefits of LASIK treatment, you must undergo a series of eye exams to ensure that you are a good candidate for LASIK eye surgery. These tests will examine the health of your eyes along with their vision.

Before performing the LASIK surgery exam, the doctor will use eye drops to dilate your eyes as it allows him to examine them more carefully. The drops may cause blurry vision for about 4-6 hours and it is suggested that you don’t wear your contact lenses in the weeks before the tests to ensure that the eye specialist gets correct examination results before performing LASIK.

Various tests that determine the suitability of the patient include:

  • Corneal Examination

    The shape of the cornea will be studied, along with its inside and outside surfaces. A device known as a corneal topographer is used to measure the eye’s curvature and create a map of the eye before the LASIK surgery. This helps in determining the specifications for the surgery. The overall thickness of the corneal walls is checked to determine corneal strength before LASIK and also look for corneal diseases or abnormalities. A thin cornea can cause problems and thus make you non-eligible for LASIK.

  • Intraocular Pressure

    Intraocular pressure examination is done to rule out the chances of glaucoma in your eyes. Glaucoma is an eye-condition that is caused by an increased pressure in the eyes and it could possibly damage the vision and the optic nerve. This usually occurs when the fluid in the eye cannot drain properly, therefore, putting pressure on the optic nerve as a result. You must be examined for glaucoma before undergoing LASIK eye surgery as symptoms can often go undetected in its early stages.

  • Lubrication of Eyes

    Tear production is absolutely crucial to the cornea as tears keep the eyes moist, help in healing wounds and prevent infections. As a pre-operative LASIK test, the eye specialist would scan for the quantity and quality of tears to determine if you are at an increased risk of dryness in your eyes post surgery. If the tear production is satisfactory, he/she would go ahead with the surgery.

  • Pupil Size

    One of the critical pre-operative LASIK tests is conducted by measuring the pupil size of the patient. Those with larger pupils could possibly be at risk of side effects like glare or halos post their LASIK eye surgery.

  • Refraction

    It is important to accurately measure the degree of your prescription. The doctors will examine you for short-sightedness, long-sightedness and astigmatism and the extent of it. To be eligible for the LASIK procedure, you must have a refractive error that has been stable for over a year. The spectacles prescriptions will be confirmed multiple times during the tests and the whole LASIK treatment.

  • Image Quality of Eyes

    Our eyes work as a camera which allows us to see great quality images. The LASIK surgeon in Fresno will scan your eyes to determine the quality of the image that your eye can produce after it is fully corrected with the glasses. The ‘aberrations’ will be measured and it would be assured that the eye is properly focused and capable of producing good images.

  • Medical History

    This isn’t a test, however, it is a crucial part to understand a patient’s medical history. You must inform the doctor of any pre-existing medical conditions that may be a possible threat to your vision after your LASIK operation. The doctor will discuss your lifestyle changes, the medication and prescriptions required post-surgery.
