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.
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.
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.
