Cataracts Q:
My husband and I are both 65 years old and have age-related need
for reading glasses. Is there a safe, tested method like LASIK to
remedy this?
A: There are presently several methods to deal
with your problem, which is called presbyopia. One is to use a contact
lens to focus one eye at reading distance and leave the other eye
focused for long range. This is called monovision and is used commonly
in the 40 to 50 plus age range. In higher powers it has the disadvantage
of reduced depth perception and, in some people, a feeling that
the eyes are fighting each other. Bifocal contact lenses, both soft
and gas permeable, are often used to give more natural distance
and near vision. Surgically, the most promising techniques are basically
cataract surgery. Known as refractive lensectomy, the patient’s
internal lens is replaced with an implanted artificial lens. In
this case the implanted lens is able to focus, to a greater or lesser
degree, and gives the patient clearer near vision. It is sometimes
necessary to use reading glasses for tiny print, but for most tasks
near vision is adequate. These lenses are still new and the technology
is still evolving, but more and more surgeons are utilizing them.
They are not covered by Medicare, so the patient must pay an additional
fee.
