If you think surgical correction of nearsightedness, farsightedness, and/or astigmatism may be for you, the most important choice you will make is the doctor, even more important than deciding whether or not to have the procedure. A conscientious surgeon will help you decide whether excimer laser treatment is right for you by highlighting the pros and cons as they relate to your particular situation. The surgeon should discuss the advantages and disadvantages of PRK, LASIK and nonlaser procedures to help you choose which technique is best for you. The surgeon will also perform the procedure.
