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

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?
