Am I Eligible for LASIK? A 10-Point Checklist

Thinking about ditching your glasses or contact lenses for good? Before you book a consultation, run through this quick self-check — it won't replace a proper eye evaluation, but it will tell you whether LASIK is likely to be an option worth exploring for you.

Only a detailed corneal topography and eye examination at a clinic can confirm final eligibility — but this checklist is a great place to start.

The 10-Point Self-Checklist

Before you dive into the list, it helps to understand what LASIK actually corrects. LASIK reshapes the cornea — the clear front surface of the eye — using a computer-guided excimer laser, so light focuses precisely on the retina instead of in front of or behind it. Because it's a precise, permanent reshaping of living tissue, surgeons screen for a specific set of conditions before recommending it. Go through each point honestly; ticking most of them is a strong sign, but the final call always rests on your actual corneal measurements, not a guess.

1. You are 18 years or older. LASIK requires a stable, fully developed eye — most surgeons prefer patients to be at least 18–21, since both the eye and the prescription can still be changing in the late teens.
2. Your power has been stable for at least 12 months. If your spectacle prescription is still changing every few months, LASIK should wait — operating on a moving target means the correction may not hold as well.
3. You don't have very thin corneas. LASIK removes a small amount of corneal tissue to reshape it; adequate corneal thickness is essential so enough structural tissue remains afterward, which we confirm precisely via corneal topography and pachymetry.
4. You haven't been diagnosed with keratoconus. A cone-shaped or irregular, progressively thinning cornea generally rules out standard LASIK, because the procedure can accelerate this weakening. Keratoconus needs its own dedicated management.
5. You are not currently pregnant or breastfeeding. Hormonal fluctuations during pregnancy and lactation can temporarily change corneal shape and thickness — surgeons recommend waiting until a few months after breastfeeding ends for a stable, accurate measurement.
6. Your eyes are not severely dry. Significant chronic dry eye needs to be diagnosed, treated and stabilised before surgery, because LASIK temporarily reduces corneal sensitivity and can worsen unmanaged dryness during healing.
7. You don't have uncontrolled diabetes or autoimmune disease. These conditions can affect corneal healing and raise infection risk; well-controlled diabetes or autoimmune conditions are usually not a barrier, but your surgeon will want recent reports.
8. Your power falls within a treatable range. Most modern LASIK and Contoura Vision platforms treat a wide range of minus (myopia) and plus (hyperopia) power along with astigmatism, but extremely high prescriptions on thinner corneas may need alternatives like an ICL instead.
9. You understand LASIK doesn't prevent age-related presbyopia. Around your mid-40s, near reading vision changes for everyone as the eye's natural lens stiffens — LASIK corrects your current distance prescription, not this future age-related change, so reading glasses may still be needed later regardless of surgery.
10. You're not in a profession with LASIK restrictions. A handful of specific professions (some defence, aviation and government roles) have entry vision requirements or waiting periods after refractive surgery — worth checking with your employer before booking, if relevant.

Why These Eligibility Criteria Exist

None of these ten checks are arbitrary — each protects a specific part of the outcome. Corneal thickness and shape checks exist because LASIK's safety margin depends on how much healthy tissue remains after the laser reshapes the surface; operating on a cornea that's already thin or irregular raises the risk of a rare complication called corneal ectasia, where the treated cornea slowly bulges forward over months or years. Stability checks exist because a prescription that's still shifting means the "target" for the laser keeps moving — operate too early and the correction may simply drift over time. Health checks exist purely around healing quality: LASIK creates a thin corneal flap that needs to heal cleanly, and anything that slows or disrupts healing — poorly controlled sugar, active autoimmune flares, unmanaged dry eye — raises the chance of a rougher recovery.

This is precisely why Sentra Clinic never quotes LASIK eligibility over a phone call or WhatsApp message. A screening with actual instruments — corneal topography, pachymetry and a dilated retina check — takes the guesswork out of all ten points at once.

Ticked Most of These? Here's What Happens Next

If you nodded along to 8 or more of these points, there's a good chance you're a strong LASIK candidate — but the only way to know for certain is a detailed screening, because a few of these checks (exact corneal thickness, precise topography shape) simply cannot be self-assessed at home. At Sentra Clinic, this includes corneal topography, pachymetry (corneal thickness), a dilated retina check and a full discussion of which procedure — LASIK, Contoura Vision or ICL — best fits your eyes. The whole screening typically takes under an hour, and you'll leave with a clear yes/no answer plus a recommended procedure, not a vague "maybe."

The Screening Process: What to Expect

1. Detailed history & current prescription check. We review how long your power has been stable, any past eye issues, medications and general health.
2. Corneal topography. A painless scan maps the exact 3D shape and thickness of your cornea, screening out keratoconus and irregular corneas immediately.
3. Pachymetry. A precise measurement of corneal thickness at multiple points, confirming there's enough tissue to safely reshape.
4. Tear film & dry eye assessment. Quick tests check whether your tear quality and quantity are adequate for a smooth recovery.
5. Dilated retina examination. Drops widen your pupils so the surgeon can check your retina is healthy before clearing you for any refractive procedure.
6. One-on-one consultation. You get a clear recommendation — LASIK, Contoura Vision, ICL, or "not yet, here's why" — with every question answered before you decide anything.

What If I'm Not Eligible for LASIK?

Not qualifying for standard LASIK is far more common than people expect, and it is not the end of the road — it simply means a different, equally effective procedure is likely a better fit for your specific eyes. A meaningful share of people who come in wanting LASIK end up better suited to one of the alternatives below, often because of corneal thickness, shape or a very high prescription.

Life After LASIK: What to Expect

Most patients notice a dramatic improvement in vision within a day of the procedure, with full stabilisation over the following one to two weeks. Mild dryness, light sensitivity and occasional glare around lights at night are common in the first week or two and settle as the cornea heals. You'll typically be advised to avoid swimming pools, eye makeup and rubbing your eyes for a couple of weeks, and to attend a short series of follow-up visits so your surgeon can confirm the cornea is healing exactly as expected. Beyond that, it's simply life without needing glasses or contact lenses for distance vision — though remember point 9 above: presbyopia in your mid-40s onward is a separate, unrelated part of aging that LASIK does not prevent.

How to Prepare for Your LASIK Screening

A little preparation makes your screening more accurate and saves you a second visit. If you wear soft contact lenses, stop wearing them for at least a week before your appointment; for rigid gas-permeable lenses, your clinic may ask for a longer break, since lenses can temporarily flatten or distort the cornea and skew the topography readings. Bring your current spectacles and, if you have them, any previous prescription records or old topography reports — a history of how your power has changed over the past year is genuinely useful to the surgeon. Avoid wearing eye makeup on the day, and set aside about an hour so the dilating drops (if used) have time to work without you feeling rushed. Arrive with a list of any medications, ongoing health conditions, and questions you want answered — nothing is too small to ask before you commit to a permanent procedure.
