Monovision eye surgery is an effective way to treat presbyopia, the age-related farsightedness that requires most people over the age of 40 to use reading glasses from time to time.
Most people choose to correct their vision with bifocal glasses or bifocal contact lenses. However, monovision eye surgery is growing in popularity as a way to combat presbyopia without the need for contacts or glasses.
Many people with presbyopia are unsure what monovision is. Monovision is a procedure that corrects one eye for distance vision, while correcting the other eye for near vision. Because the dominant eye is treated for distance vision, the brain is easily able to compensate for the two different levels of correction.
There are several different methods of attaining monovision, including contact lenses, intraocular lenses, and LASIK monovision eye surgery. Your ophthalmologist can help you decide what the best choice is for your monovision procedure.
LASIK Monovision Surgery
Monovision LASIK surgery is the most recent development in presbyopia treatment. Rather than using glasses or contacts to achieve monovision, Lasik surgery can permanently correct one eye for distance vision and the other for near vision, allowing patients to reduce or eliminate their dependence on glasses and contacts.
As with any type of surgery, LASIK monovision surgery has some potential problems associated with it. Because the eyes are designed to work together to focus on objects, monovision may interfere somewhat with depth perception. Also, monovision eye surgery can cause reduced peripheral focus in certain circumstances, for instance when patients glance quickly at rear-view mirrors in the car.
Because monovision surgery is permanent, it is recommended that patients first try monovision with contact lenses to determine whether problems might occur. Though it takes a while to adjust to monovision after surgery, most people are pleased that they no longer have to rely on reading glasses or bifocals.
