LASIK: Q&A
Ask a Question
PRK Performed Twice?
I have had 2 LASIK procedures already (original and one enhancement). Several years since my LASIK enhancement surgery. My right eye has 0.75 of astigmatism. The doctor said he doesn't recommend I do PRK but would do it if I requested. However, he told me PRK is a one time procedure and if I'm not satisfied with the result, I wouldn't be able to do it again. Is this true? If I get PRK now (I'm in my mid 30's), can I do it again (a 2nd time) when I'm in my 50's to treat presbyopia?

PRK enhancement and presbyopia
There is not a limit to how many times you can have an enhancement. However, we are limited by the amount of corneal tissue. You can only take away a certain amount before you interfere with the structural strength of the cornea. In addition, We don't usually do more than one enhancement as there should be few reasons to ever have to do a third enhancement. PRK/Lasik do not currently treat presbyopia.

Recommendation
Best way to treat presbyopia is with Refractive Lens Exchange. Going back once more to treat astigmatism with PRK will increase your chances of having a weak cornea, which you already seem to have with two Lasik enhancements.

PRK over LASIK as a method of enhancement
Typically in my office, I feel comfortable picking up LASIK flaps for the first year or two. For someone who needs an enhancement to their LASIK result past this time, is from another surgeon, or where there is concerned about adequate corneal thickness I suggest PRK as an enhancement. The nice thing about PRK is that it is safer than LASIK, but it does take longer to heal. As long as the cornea is healthy and there is enough corneal thickness remaining, multiple PRK...
