Monovision can allow patients over age 45 to see up close AND in the distance without glasses. With Monovision, one eye is corrected to see well in the distance and the other eye to see well up close.
How does monovision work?
Monovision patients see clearly in the distance with one eye and up close with the other. Successful monovision patients automatically ignore the vision in the up close eye when looking in the distance and ignore the vision in the distance eye when looking up close. There is no need to close one eye. Your brain automatically selects the eye with the clearest vision.
Are you a candidate?
To know if you are a candidate for monovision you must try it using contact lenses prior to your surgery. The major problem with monovision is that many people are unable to tolerate it. For monovision to work successfully, your brain must ignore the vision in the eye that is not being used. This requires no training or learning, it simply happens. Motivation, time and effort will NOT improve your chances of tolerating monovision. Your brain will either accept it or it won’t. That is why a simple trial of contact lenses is essential to help you determine if you are a monovision candidate.
When is monovision a good choice?
Both LASIK surgery and PHASER surgery can be used for monovision corrections. Deciding which procedure is best for each individual patient requires evaluating a number of factors including age, nearsightedness and farsightedness, astigmatism, and the presence or absence of cataracts . An in-office face-to-face discussion is necessary to help with this decision.
WHAT IF I DO NOT LIKE MY MONOVISION
In most cases, monovision can be reversed. However, while the risk of most of these surgeries is very low, the risk is always greater when trying to undo what has been done than the risk of the original procedure. Therefore we are very careful in selecting which patients will be good monovision patients.
