Photorefractive keratectomy (PRK): Questions about this eye surgery

Posted by mslc @mslc, Nov 20, 2021

In 2015, I had PRK that corrected my vision from -4.5 to seeing 20/20 (sometimes even 20/15) and my vision had been stable for at least 3 years. In 2019 I was given a small prescription (.25) to wear while at the computer and this year I got one for -.75 for astigmatism. Is it normal for this to happen? If I had perfect vision for 3 years after the surgery, could this be a cause of anything from the surgery?

Hi @mslc and welcome to Mayo Clinic Connect.

I see that you are asking if your declining eyesight is normal after a PRK.

I'd like to invite @maryb1996 to the conversation who has discussed having a PRK surgery and eye problems later.

You might be interested in reading this article about the surgery and regression a year later:

When you obtained your prescription, did you ask your optometrist about this?
