What Are the Long Term Side Effects of a PRK Eye Operation?

I feel I can address this question very well, since I had PRK on both of my eyes in 1994! My prescription was about a -5.00, so on the moderate scale of things, though the laser systems in place at that time were pretty rudimentary compared to today. I can say nothing but positive things about my PRK surgical experience, as well as my long term results. I have had no regression of effect of PRK, though we did see that in a small group of patients with the early lasers. Regression using the... more

We have been performing PRK for 25 years, so there is a wealth of long-term follow-up information based on actual patients.

Patients seldom regress all the way to their previous prescription, but some do require a touch up. Some patients experience an increase... more
