The Lasik Monovision Decision

If you decide to go the lasik route because presbyopia has become a problem, you have to make a choice.   One option is to have both eyes adjusted for the best possible distance vision, and then use glasses for reading.

Many, however, choose another solution - lasik monovision.  One eye is adjusted for far vision, and the other for close vision.   This technique offers the possibility of doing completely without glasses - at least for a time.

Monovision was first talked about 40 years ago, and has been has been used with lots of success for over 20 years.  Normally the stronger eye is corrected distance vision and the weakest eye for near vision.

Strange but true, once the lasik monovision surgery has been done, the brain starts to compensate.   It ignores the eye producing the out-of-focus image. The result is that within six to eight weeks most people have adjusted completely to the changed images they are receiving.

However, this is not always the case.   About 15% of people who choose lasik monovision can't adjust to the change. They then usually have a second treatment to make both eyes the same, and just use glasses as well.
