Monovision is a refractive surgery technique used for patients with presbyopia. Presbyopia is the loss of ability to focus on objects close up due to the normal aging process. It will affect everyone as they enter their 40’s. The technique uses refractive surgery to enable one eye to focus for close vision, and the other eye is left untreated, or, if needed, treated to be able to focus for distance vision. While monovision will reduce a patient’s need for glasses or contacts, glasses may still be necessary for fine print.
It is important to discuss your lifestyle with your surgeon prior to making a decision. It can be difficult for some patients to adjust to monovision. The brain will eventually adjust after six to eight weeks, but that may not be acceptable for some patients. In addition, active individuals that play golf or tennis or drive a great deal at night may not be good candidates for monovision.
