After 8-9 years from my first PRK, some nearsightedness returned (about -0.75). Is it advisable to try PRK again?

raffyuyDec 7, 2017
8+ years ago I had around -6.00 myopia before PRK. Recovery was good and results were great. A year ago, my vision changed (probably about -0.25) which I tolerated. After going on a ski trip, I noticed my vision worsened to about -0.5/-0.75. I suspect the dry weather lack of sunglasses under strong sunlight on snow degraded my vision. I visited my doctor again and he said I can still do PRK but there's a small risk of irreversible scarring. I really do not like wearing glasses. Should I risk it?

PRK recovery varies by patient. 20/50 isn't a concerning visual acuity at one month, although most patients do see better than that. I would continue using preservative free artificial tears every 1-2 hours and returning to your doctor for regular follow up visits to monitor for any changes. ...

More rest will not hurt the healing process. Although plenty of rest is great for your healing, you do not have to keep your eyes shut for 3 days. Using your preservative free artificial tears every 1 or 2 hours will speed up your healing. I also recommend 1000mg of Vitamin C daily and UV pro...

Sometimes after PRK, you may get some inflammation which then leads to scarring in the cornea. This scarring appears as blurry vision to you. It is possible for vision to improve, but may take 6- 12 months. However, if vision does not improve after that time, you may consider PTK, ...

A prescription for Restasis drops to use twice a day will help. I will often prescribe Restasis before refracticve surgery to avoid post-op dry eyes. Lubricating ointments like Refresh PM or Muro ointment ointment before you go to bed may also be helpful.

I would seek a second opinion from a local refractive suergeon, if you are not satisfied with your current doctor. Irregularities of the cornea my be fixed with contact lenses, or you may require repeat PRK. You may also have a cataract that are causing your symptoms.
