LASIK is a relatively new surgery (it was approved by the U.S. Food and Drug Administration in 2000). Little is known about the long-term outcomes. Doctors continue to improve the technique and to study the long-term results.
Over the short term, LASIK has been shown to be effective and consistent in reducing mild to moderate farsightedness.
LASIK is better at treating lower levels of farsightedness than higher levels. LASIK is not as consistent or safe for people who have more severe farsightedness.
