Lasik Monovision Correction: Alternative for Presbyopia
The clarity of vision is affected as a person ages. Forty seems to be the age when most people begin to lose the ability to focus. This does not mean that one has a vision-related illness; instead, it is a natural phenomenon that occurs to many people at this stage. Inability to focus means that the eyes are not capable of adjusting images seen at different distances. In order to correct this, different glasses with different focal lengths are needed for both near and distance vision. Usually, when this condition strikes a person, he will notice the difference between his vision when he was much younger and at the present. Scientifically, this condition is called Presbyopia. It is often corrected with bifocal glassses, i.e. one lens is for near vision and the other is for far vision. Though bifocal glasses are a popular choice of remedy to this condition, a more modern approach can be done to treat Presbyopia. This approach is called Monovision, which can be achieved through wearing contact lenses or via refractive surgery.
The choice of whether to get Monovision correction or to have both eyes corrected for farsightedness really depends on the patient. If patient is facing dilemma in making decision, contact lenses can be used prior to surgery to simulate the post-operative results to aid the patient in deciding.

Lasik Monovision is one of
the refractive surgeries performed to correct Presbyopia.
Lasers are used in this procedure to correct one eye for farsightedness and the other eye
for nearsightedness. By performing this procedure, it will
eliminate the need for bifocal glasses since the eyes can
focus at different focal lengths now.
