If you are between 18-55 years of age and your eye doctor has diagnosed you with nearsightedness, farsightedness, or astigmatism – and you are currently wearing glasses and contact lenses – that is a 90% probability that you are an ideal candidate for LASIK. Surveys of LASIK find rates of patient satisfaction between 92 and 98 percent. Ideal patients are at least 18 years old, have generally healthy eyes free from diseases, scars, or infections, and are willing and able to stop wearing contacts for two to four weeks before your LASIK consultation. This is because contact lens reshape your cornea and can cause ocular surface disease and corneal drying.
