Mono vision lasik or mono vision eye surgery is used to treat ‘Presbyopia’, the age related farsightedness; that requires most people over the age of 40 to use reading glasses from time to time.
Many people who suffer from presbyopia are unaware of mono vision. Actually mono vision is a procedure that corrects one eye for distance vision, while correcting the other eye for near vision. As the dominant eye is treated for distance vision, the brain is easily able to compensate for the two different levels of vision.
Mono Vision Lasik:
One of the ways to treat presbyopia is mono vision. Normally both the eyes work equally when we look at an object, to produce a vision called ‘binocular vision’. But still we have a dominant eye which is favored by the brain to sight a vision. Contact lens filters often take advantage of this “one eye dominance”, in order to produce mono vision with contacts: they fit one eye for distance vision and the other for near vision.
Lasik surgery can permanently correct one eye for distance vision and the other for near vision, allowing the patients to reduce or eliminate their dependence on glasses and contacts.
During laser surgery for mono vision, the surgeon uses a tiny blade to create a flap on cornea, or clear front layer of the eye. Then laser is used to reshape the cornea so that it will focus light more efficiently. To complete Lasik Mono vision Surgery, the corneal flap is put back at its place.
Problems Of Mono Vision Lasik:
The problems of mono vision lasik surgery are:
- As the eyes are designed to work together to focus on objects, mono vision may interfere somewhat with depth perception.
- Mono vision surgery can cause reduced peripheral focus in certain circumstances, for instance when patients glance quickly at rear view mirror.
- As mono vision surgery is permanent, it is suggested to have a test of mono vision with contact lenses first. This will make you aware of the problems that you might face.
