Photorefractive keratectomy (PRK): Questions about this eye surgery
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?
