Question: I
have two toric lens implants for monovision-one set for distance and the other
set for close vision but I still wear glasses for intermediate vision. I am
very dizzy and have balance problems. Could it be the two different lens
implants? Could they be replaced with other lenses to solve the problem?
Answer: Monovision correction with
lens implants can be a very good option for many patients to help with
correction of both distance and near vision. Some patients are simply unable to
tolerate the difference in the correction between the eyes as we say that they
have a low “tolerance to defocus.” This may very well be a cause of the
dizziness and the balance problems but may not be the sole cause or even the
primary cause. You do not state your age or general medical condition. If you
have any risk factors or a history of vascular problems, high blood pressure or
stroke this must also be ruled out as well. Further, the improper orientation
of astigmatism correcting toric
lens implants can also cause what you describe. If the problem turns out to be
the monovision correction from the toric lens implants, depending on the length
of time since your surgery it may possible to perform a lens exchange and
correct both eyes for distance or you may need a LASIK procedure to
create a distance correction for both eyes. All of this should be discussed
with your cataract surgeon who can provide
you with the information after a clinical exam and of course should you have
any other risk factors mentioned above you should consult your Internist or
family doctor as well.
