 The
standard intraocular lens implant is a foldable, monofocal
lens constructed of either medical-grade silicone or acrylic
materials. The lens is inserted folded into the eye through
a microscopic, self-sealing sutureless incision and then unfolded
and rotated into proper position. Being a monofocal lens (one
focal length), the intraocular lens corrects for either
distance or near vision but not both. This is the type
of lens implant that has been used for decades, has a superior
safety record and compatibility profile and is covered by
Medicare and most third-party health insurances (less any
applicable deductibles or co-pays). The pre-operative evaluation
will determine the lens implant power that is consistent with
the ideal target post-operative refraction.
Premium Multi-focal and Astigmatic Lens Implants
 Recently,
the FDA approved multifocal and astigmatic
lens implants such as Alcon’s ReSTOR® (www.acrysofrestor.com),
AMO’s ReZOOM® (www.rezoomiol.com),
Eyeonic’s Crystalens® (www.crystalens.com/index.htm)
and Alcon’s AcrySof® Toric lens implant. These newest,
advanced lens implants are built on the same tried-and-true
platform of the existing monofocal lens implants and are proven
safe and effective in properly selected patients. These intraocular
lenses, similar to a progressive type of bifocal eyeglass
lens, helps to correct both near and far vision. Factors that
patients consider in selecting one of these premium lens implants
include: less dependence on eyeglasses for both distance and
near, better uncorrected distance visual acuity with elimination
of astigmatism and monovision in which one eye is made to
focus at distance and the other eye made to focus at near.
Once the surgeon determines that a patient is indeed a candidate
for one of these premium, upgraded intraocular lens implants,
options can be presented to the patient prior to surgery.
Unfortunately, these premium lens implants are NOT covered
by Medicare and other third-party health insurance and, as
such, have additional fees associated with their use.
These considerations can be discussed at the time of the pre-operative
evaluation.
The surgeon can then help guide the patient through the decision
making process but it is reassuring to know that it is
almost impossible to make a wrong decision. Cataract surgery,
if recommended by your surgeon, with any appropriate expectations
and choice of lens implant is most likely going to result
in some level of improved vision and enhanced life.
