Types of Lasik Surgery and How to Choose the Right One?

  Last Updated on May 27, 2026 by Aaron Barriga

There are three kinds of people: those who love flaunting their quirky and cool glasses, second who swear by contact lenses, and the third group consists of those who can’t wait to get rid of glasses/contact lenses. If you fall in the third category, then LASIK is your savior.

LASIK, which stands for Laser in-situ Keratomileusis, is a corrective surgery used to fix common vision problems such as near-sightedness, far-sightedness, or astigmatism. It uses a specialized laser known as an ‘excimer’ laser, which reshapes the cornea to give better, clearer, and focused vision. Excimer laser precisely removes extremely tiny amounts of tissue without disturbing adjacent tissues.

Types of LASIK Eye Surgery

There are 5 types of LASIK procedures. Consultation with your doctor will help in determining which one will give you the best results.

1. Traditional LASIK

This is the original version, and it’s been performed safely for over two decades. A small precision blade called a microkeratome creates the corneal flap. Then a separate excimer laser reshapes the underlying tissue based on your prescription. The flap goes back, you go home, and most people are seeing clearly by the next morning.

It’s fast, well-studied, and widely available. For patients with a straightforward prescription and healthy corneal thickness, it works really well.

The main limitation is the blade itself. It’s precise, but a small number of people experience flap-related issues. And if your corneas happen to be on the thinner or more irregular side, your surgeon may steer you toward a different option.

2. Bladeless (All-Laser) LASIK — iLASIK / IntraLase

Everything about this is identical to traditional LASIK — except instead of a blade, a femtosecond laser creates the corneal flap. This laser fires ultrafast pulses of light to separate the tissue at a very precise, programmable depth.

The result is a more uniform flap with less variability, which many surgeons prefer. There’s also a slightly lower risk of flap complications compared to the blade method.

It costs a bit more, but a growing number of clinics now offer this as their default approach. If you’re given the choice and budget isn’t the deciding factor, most people find the peace of mind worth it.

3. Custom LASIK (Wavefront-Guided)

Your glasses prescription tells your doctor how much correction you need in broad strokes. But your eye has subtler quirks beyond that. These are tiny distortions called higher-order aberrations that standard lenses can’t address. You might not even notice them consciously, but they can show up as halos around streetlights, reduced sharpness in dim rooms, or that slight sense that your night vision has never quite been right.

Wavefront-guided LASIK maps these individual imperfections before surgery using a wavefront analyzer, essentially a detailed optical fingerprint of your eye. The excimer laser is then programmed to correct your specific distortions, not just a generic prescription.

People who go this route often report noticeably better night vision and fewer complaints about glare compared to standard LASIK. It costs more, but if quality of vision matters a lot to you, especially in low-light situations, it’s worth asking your surgeon about.

4. Topography-Guided LASIK (Contoura Vision)

Some people have corneal surfaces that are slightly uneven. not dramatically, just enough that a standard approach won’t give the cleanest outcome. Topography-guided LASIK takes a highly detailed map of your cornea’s surface and uses that to guide the laser, smoothing irregularities as it corrects your vision.

It’s also a strong option for people who had LASIK years ago and weren’t fully satisfied with their results. In some cases, it can fix what the original procedure left behind.

Clinical outcomes have been impressive. Studies show a higher percentage of patients achieving better than 20/20 vision compared to other methods. It requires specialized equipment, so not every clinic offers it. But if your corneas have been described as irregular or asymmetric, it’s absolutely worth asking about.

5. Wavefront-Optimized LASIK

This one doesn’t map your individual aberrations, but it’s smarter than basic LASIK. It uses a built-in algorithm that accounts for the natural curve of your cornea when applying the laser. Why does that matter? Because a flat laser pattern applied to a curved surface can inadvertently introduce new distortions, a problem called spherical aberration. Wavefront-optimized treatment is designed to prevent that from happening.

Think of it as a sensible upgrade that doesn’t cut corners. It’s more affordable than fully custom LASIK and delivers excellent results for people with typical prescriptions who don’t have significant pre-existing higher-order aberrations.

How to Choose the Right Type of LASIK Surgery?

Choosing the right type of LASIK can feel overwhelming, especially when every option sounds impressive. The good news is that it doesn’t have to be. Here are the key things to consider before you make a decision.

1. Get a Thorough Pre-Surgery Evaluation – First Let your surgeon assess your corneal thickness, shape, and prescription stability before anything else. That data will guide the recommendation, not the other way around.

2. Consider Your Night Vision Needs – If halos, glare, or poor night driving are already a concern, ask about wavefront-guided LASIK. It addresses optical distortions that a standard procedure won’t catch.

3. Know Your Corneal Health – Thin, flat, or irregular corneas change which procedures are safe for you. Always share your full eye history with your surgeon before your consultation.

4. Be Honest About Dry Eyes – Some LASIK types affect corneal nerves more than others, which can worsen dry eyes. If it’s already an issue for you, mention it early so your surgeon can factor it in.

5. Factor In Your Lifestyle – Active job, contact sports, or long screen hours? These details matter. Certain procedures suit high-physical-risk lifestyles better than others.

6. Set a Realistic Budget – Advanced procedures cost more, but the difference in outcome isn’t always dramatic. Ask your surgeon plainly what you gain or lose at each price point.

7. Ask About Enhancement Options – Some procedures make touch-up treatments easier if your vision isn’t perfect after healing. It’s a simple question that’s worth asking before you commit.

8. Trust the Surgeon – Who Explains Their Reasoning A good surgeon tells you why a procedure suits your eyes, not just which one to book. If something feels rushed or unclear, a second opinion is always okay.
