I know exactly what goes through your mind when you start thinking about LASIK eye surgery. You are tired of reaching for your glasses the moment you wake up. You are done with dry, irritated eyes from contact lenses. You have heard that LASIK changes lives — and you want that too.

But here is something most people do not tell you before you book that appointment: LASIK is not suitable for everyone. And whether your surgery succeeds or not depends as much on the evaluation done before the procedure as it does on the laser itself.

I have put together this honest, practical checklist of 10 things you must check before going for LASIK. Read this before you make any decision — your vision is worth the extra few minutes.

1. Is Your Eye Power Stable?

This is the very first thing your doctor will check — and for good reason. Your spectacle power should not have changed by more than 0.5 diopters over the last 12 months minimum. If your power is still fluctuating, the laser correction may not give you stable long-term results, because the eye it corrected may continue to change after surgery.

If you are in your late teens or early twenties, I would honestly suggest waiting a little longer — even if it feels frustrating — until your prescription settles. The results will be far more reliable.

2. Are You 18 Years or Older?

LASIK is approved for adults 18 and above, but many surgeons — including our team at Dr Rishi Eye Institute — recommend waiting until your early-to-mid twenties if your power has been changing recently. Age alone does not make you a candidate; stable vision does.

3. Is Your Cornea Thick and Healthy Enough?

This is probably the most critical technical check before laser eye surgery. LASIK involves the re-sculpting of the cornea through the use of a laser, which means that the cornea needs to have enough thickness for the procedure to be performed safely. In case the cornea is too thin, it could be weakened through the removal of tissue in the process of LASIK.

Some tests can help measure the thickness of your cornea, known as pachymetry, as well as a mapping of its shape called corneal topography. However, just because your cornea is unsuitable for LASIK does not mean that you cannot have ICL surgery done.

4. Do You Have Dry Eyes?

Dry eye is one of the most common reasons LASIK is delayed or reconsidered. The procedure can temporarily reduce corneal sensitivity, which affects how your eyes produce tears. If you already have significant dry eye disease before surgery, LASIK can make it considerably worse afterwards.

Your pre-LASIK evaluation should always include a tear film test. If dry eyes are detected, they need to be treated and stabilised before any surgical decision is made. This is not a reason to give up on LASIK — it is a reason to go in properly prepared.

5. Are Your Eyes Free from Underlying Disease?

Before recommending LASIK, your eye surgeon will examine your eyes thoroughly for any conditions that could affect the safety or outcome of surgery. Conditions that may delay or rule out LASIK include:

Keratoconus — a progressive corneal thinning condition
Glaucoma — high eye pressure that can be worsened by surgical procedures
Cataract — which will affect vision regardless of laser correction
Active corneal infections or corneal scars
Retinal disorders that need treatment first
Severe, uncontrolled eye allergies

If any of these are found, treating them first is not a setback — it is what responsible eye care looks like.

6. Are You Pregnant or Breastfeeding?

When you are pregnant or breastfeeding, it is best to postpone LASIK. The hormonal changes that occur during this time may temporarily alter the refractive power of your eye, so even if you undergo surgery and your prescription is corrected today, it will no longer be valid once your hormones stabilize.

7. Do You Have Realistic Expectations?

LASIK eye surgery in Haryana and across India delivers excellent results for the vast majority of patients. Most achieve 6/6 vision or very close to it. But “perfect” vision without any need for glasses ever again cannot be guaranteed for everyone. Halos or night vision changes can occur early during recovery, and some patients may be affected by these changes permanently.

It is very important to know about the potential results, limitations, and natural progression of your visual acuity before undergoing the procedure. With accurate information, you will surely be happier with the outcome of your procedure.

8. Have You Stopped Wearing Contact Lenses?

This is a step many patients overlook — and it genuinely affects the accuracy of your pre-LASIK evaluation. Contact lenses, especially rigid ones, can subtly alter the shape of your cornea over time. If you are still wearing lenses right up to your evaluation appointment, the corneal measurements your doctor takes may not reflect your true corneal shape.

Soft contact lenses: stop wearing them at least 3 to 7 days before your evaluation
Rigid or toric lenses: discontinue for 2 to 4 weeks or longer as advised by your surgeon

Ask your doctor for exact instructions based on the type of lens you use.

9. Have You Chosen an Experienced Eye Surgeon?

LASIK outcomes depend equally on two factors: the technology used and the surgeon performing the procedure. Advanced laser equipment in the wrong hands — or without a thorough pre-operative workup — will not give you good results.

When choosing where to have your laser vision correction, look for:

An ophthalmologist with specific experience in refractive surgery
A centre that performs thorough pre-operative evaluation — not just a quick check
Transparent counselling about whether you are a suitable candidate
Clear information about risks, alternatives, and post-operative care

At Dr Rishi Eye Institute, we never recommend LASIK to someone who is not a genuine candidate — even if they come in hoping we will. That is what patient-first care actually means.

10. Have You Had a Complete Pre-LASIK Evaluation?

Please do not consider LASIK at any centre that does not perform a comprehensive pre-operative workup. A proper LASIK evaluation must include all of the following:

Full vision assessment and accurate eye power measurement
Corneal topography — detailed mapping of corneal shape
Pachymetry — corneal thickness measurement
Tear film analysis for dry eye assessment
Eye pressure measurement
Dilated retinal examination
Detailed counselling about the procedure, risks, and outcomes

This evaluation typically takes 1 to 2 hours. If anyone offers to do it in 15 minutes, walk away.

Ready to Find Out If LASIK Is Right for You?

LASIK is not a quick procedure you should rush into. It is a carefully planned treatment that starts with one simple thing: knowing whether your eyes are genuinely suitable for it. The 10 checks I have walked you through are not meant to scare you — they are meant to prepare you.

If you are considering laser eye surgery in Haryana, the best next step is a comprehensive pre-LASIK evaluation with an experienced eye surgeon. Come in with your questions. Leave with honest answers. And make your decision from a place of clarity — not pressure.
