The Odds You Will See 20/20 After
Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, CK, P-IOL, RLE, etc.

The skill and experience of your doctor will play an important role in the probability of desired outcome. You must also remember that Snellen 20/20 is only one indication of visual clarity. Under controlled conditions you may have 20/20 vision, but in the real world you might be unable to drive a night because of debilitating halos or you have eyes so dry you can't see without putting in drops every hour or so.

To be a USAEyes Certified Lasik Doctor, a doctor must demonstrate that 90% of his/her patients achieve 20/40 or better and 65% achieve 20/20 or better with limited complication rates. See Outcomes Requirements This is what we consider to be the national norms, but your individual circumstances may indicate a significantly different result.

If you have high refractive error, your probability of a good outcome goes down dramatically. If you have a wavefront-guided ablation rather than conventional, your probability of a good outcome goes up. For most people, if you have a surface ablation technique like PRK or its cousins LASEK and Epi-Lasik, your final outcome will probably be slightly better than with Lasik or All-Laser Lasik. Outcomes for hyperopia are more difficult to predict than myopia correction (more). CK is a very different procedure than something with a laser. P-IOL and RLE are generally for people with high refractive error or early stages of crystalline lens dysfunction. If you are a 50 year old woman your outcome probabilities are significantly different than if you are a 25 year old male. Every individual is different, and every individual needs to be evaluated by a competent doctor who can advise based upon your own circumstances what you can reasonably expect.
