LASIK and PRK Statistics: Your Chances for Success
What are my chances of achieving 20/20 vision with LASIK or PRK? This is what every patient wants to know. A better question might be this: What is the likelihood that my procedure will be successful, given my refractive error? Although it would be unreasonable to be guaranteed 20/20 eyesight after vision correction surgery, it is reasonable for you to ask your doctor to predict your chances for a successful outcome.
If you have chosen an experienced surgeon-someone who has performed 3,000 LASIK procedures at the absolute minimum-he or she has most likely performed surgery on a number of patients with vision like yours. Accordingly, you will be able to get an idea of what you can reasonably expect after LASIK or PRK.
