Is LASIK Right for You? 7 Questions to Ask First

You've thought about it for years. Every morning, you reach for your glasses before you can see clearly enough to find them. Every evening you peel out your contacts after a long day. You've wondered whether LASIK could actually fix this?

The answer, for most people, is yes. But "most people" isn't everyone, and the decision deserves more than a quick Google search. Here are the seven questions our surgeons recommend every prospective patient ask before stepping into a consultation room.

1. Is my prescription stable?

LASIK works by permanently reshaping your cornea to correct your current prescription. If your vision is still changing, which is common in your early twenties, operating too soon means the correction may become inaccurate within a few years. Most surgeons want to see at least two years of stable prescription before proceeding. Bring your last three prescription records to your consultation.

2. How thick are my corneas?

This is the question most patients don't know to ask. LASIK removes a precise amount of corneal tissue to reshape the eye. If your corneas are too thin, there may not be enough tissue to work with safely. A pre-op corneal mapping scan — called topography — measures this in minutes. Thin corneas don't rule out vision correction entirely; they may make you a better candidate for PRK or SMILE instead.

3. Do I have dry eyes?

LASIK temporarily reduces corneal nerve sensitivity, which can worsen existing dry eye symptoms for several months post-op. If you already use eye drops regularly, experience burning or grittiness, or spend long hours in front of screens, mention this at your consultation. It doesn't automatically disqualify you — but it shapes which procedure is safest for you.

4. What's my pupil size in low light?

In dim environments, your pupils dilate. If your pupils dilate wider than the laser's treatment zone, you may experience halos or glare around lights at night — particularly when driving. Modern lasers have larger treatment zones than earlier generations, but pupil size remains a relevant factor worth discussing.

5. Are there any corneal irregularities?

Conditions like keratoconus — a progressive thinning of the cornea — can be worsened by LASIK if undetected. A thorough pre-op screening using corneal topography will identify any irregularities before surgery is considered. This is one reason why choosing a clinic that performs comprehensive diagnostics matters.

6. What are my realistic expectations?

LASIK achieves 20/20 vision or better in the vast majority of patients. But "better" doesn't always mean perfect. Some patients still need thin glasses for night driving or reading after a certain age. Going in with clear expectations and a surgeon who sets them honestly leads to far higher satisfaction rates.

7. Who is actually performing my surgery?

This one surprises people. At some clinics, initial screenings are handled by technicians, and the surgeon only steps in for the procedure itself. At Visara, your consultation, screening, and surgery are all performed by the same board-certified refractive surgeon. You should know your surgeon's name, credentials, and complication rates before you sign anything.

The Bottom Line

LASIK is one of the most studied and consistently successful elective procedures in modern medicine — but it's not universally right for everyone. The best outcome starts with an honest, thorough consultation. If you've been thinking about it, the first step is simply finding out where you stand.
