Deluxe Presbyopia-Correcting Intraocular Lens Implants
Increased Freedom from Glasses After Cataract Surgery with Presbyopia-Correcting
Deluxe Intraocular Lens Implants
Presbyopia and Cataract
As we get older, the eye begins to loose its focusing power, this is
called presbyopia. Eventually, the lens of the eye can become cloudy and
images become blurred (the cloudy lens is called a cataract).
Cataract surgery can restore vision
loss due to cataract. After a cataract is removed, an intraocular
lens (IOL) implant is placed permanently into the eye to help it focus.
The standard implant, covered by Medicare and other insurances, provides
clear vision at one distance, thus it is called a single-vision or mono-focal
intraocular lens. The single-vision IOL focus is usually set for distance
and glasses are typically needed for intermediate and near vision (trifocals
and stronger bifocals, respectively). Single-vision implants do not have
a wide range of focus, but rather one set point of focus. Single vision
implants do not correct presbyopia, the loss of focusing power.
Deluxe Intraocular Lens
Implant (IOL) Overview
Recent advances in IOL technology have produced “Deluxe”
implants that can give a much broader range of focus. These Deluxe, “presbyopica-correcting”
IOLs work by either splitting light (with refraction or diffraction technology)
to provided distant and near vision to the retina at the same time or
by changing the focus point of the implant (called accommodation).
The ReSTOR IOL uses diffraction
technology and the ReZOOM IOL
uses refraction technology to split this light so that the retina simultaneously
receives both distant and near images. The Crystalens
IOL uses accommodation technology; it changes focus of light by moving
within the eye when the eye’s focusing muscle contracts. These lenses
use three different technologies to help solve the focusing problem we
call presbyopia. All of these Deluxe lenses can provide distant, intermediate
and near vision and thus provide greater freedom from glasses. Your
surgeon will discuss the various options for Deluxe presbyopia-correcting
IOLs.
Deluxe implants are not covered by Medicare or other insurances (unlike
standard single-vision implants which are included in the cost of surgery).
The additional cost for the presbyopia-correcting deluxe IOL surgery is
paid by the patient who chooses this technology. Choosing the Deluxe IOL
is not medically necessary and completely optional. The major difference
between cataract surgery with a traditional IOL versus cataract surgery
with a presbyopia-correcting Deluxe IOL is the degree of dependence on
eyeglasses thereafter; it's probably less with the Deluxe IOL.
Most people regain good distance vision with these Deluxe IOLs (somewhere
between 20/20 and 20/40) which is very functional vision, but not necessarily
perfect vision. Glasses may be required to fine tune the vision for patients
to get their very best vision. The goal of the Deluxe IOLs is to provide
a wider range of useful vision without glasses, thus increasing freedom
from spectacles. The goal for deluxe implant patients should be functional
vision (20/40 or better) which is legal driving vision and reasonably
good reading vision but not necessarily as sharp as 20/20 distance and
near that some can expect when wearing their glasses. Results will vary
with deluxe implants, but most patients will enjoy a greater freedom from
glasses with the wider range of vision provided by the Deluxe IOLs.
