"PRK and myopia"

Dear Doctor,
I have a PRK done on one of my eyes at the end of October 2000 in Europe. My refractive error was -6.75D with no astigmatism on both eyes. My vision was better than 20/20 with contacts. During PRK the amount they shaped my cornea equalled to -6.75 D. After PRK my vision have not come back totally. The last time when it was checked at the end of December my refractive error was -1.0D sph -1.0D cyl tg 180 deg 20/20.
I am concerned about the astigmatism I have eversince.
My questions are:
1. Did they make a mistake during PRK?
2. What is the chance for patients with -6.75 D to get rid of it at once with these surgeries?
3. How many months after the first intervention can the second one be done?
4. Should more dioprties be taken off this time or just equal to my current refractive error?
5. What are the chances that there will be a residual refractive error or astigmatism after the second surgery?
6. How many months after the intervention can somebody use contacts?
I appreciate your help.
Thank you in advance. I am looking forward to your reply.
Yours sincerely,
Petra Kozma

PRK (like LASIK) reduces myopia, but your surgeon should have explained that there was a chance that you could end up over or under corrected. When this occurs, patients can have an enhancement.
most experts recommend waiting 3-6 months after the first surgery for the eye to stabalize. As well, there is still a chance that the eye will end up over or under with a second surgery, so you need to talk with your own doctor about the risks of surgery and your doctor's personal percentages.
I hope this helps

As with all laser vision surgeries, the individual healing response to the surgery determines how your outcome is. Some eyes heal less and some more to the surgery. As Dr. Trattler stated, it is important to allow the eye to stabilize before undergoing a second procedure (PRK or LASIK), usually by 6 months with a prescription like yours.
As for the contact lens, your doctor can fit you with a contact lens now to help you see better until you are stable enough to have the retreatment.
Good luck and let me know if I can answer any other questions.
