PRK enhancement after LASIK... Almost imperceptible improvement after 4 months

Question

I had LASIK surgery in 2003 in both eyes which corrected me to 20/20. After 10 years, my near sightedness gradually regressed to roughly 20/40 or 20/60. I decided to consider an enhancement, and went back to my original surgeon, who recommended PRK this time, one eye at a time. I underwent the surgery in my left eye in November 2013. Nearly four months later, best case, the improvement in my left eye has been negligible. Should I be concerned? What questions should I ask at my next appt.?

Michael K. Tracy, MD · Answer

PRK is generally considered the best way to perform enhancements after LASIK, since re-lifting the flap can lead to so many complications.  Four months is a relatively long period to see no improvement.  Your surgeon will want to asses if you have some eye condition that is affecting your vision, if you have developed haze, or if you have achieved the desired refraction (plano if this is a distance treatment).  Vision does improve for several months after PRK and longer if you were hyperopic, so this may just be normal healing.
