| Types of Contact
Lenses
The following types of contact lenses are fitted and supplied
through Eye Consultants:
Bi-focal/Multi-focal Contact Lenses
Bi-focal contact lenses have been available for over forty years but recent
manufacturing and material advancements have greatly increased the success
rate of multi-focal contact lenses. With the advent of new digital technology,
lenses can be reproduced time after time with amazing accuracy, greatly increasing
the success rate of multi-focal contact lenses and the confidence level of
patients and contact lens practitioners.
More recently there have been two or three, soft multi-focal lenses released
that have increased the success rate with soft multi-focals. For patients
who prefer rigid oxygen permeable lenses there are also several good designs.
Soft Contact Lenses for Astigmatism
Over the years as manufacturing technology has improved, soft contact lenses
for astigmatism have become highly successful and reproducible and consistently
provide excellent vision and comfort. Even patients with very high amounts
of astigmatism can now be fit with soft contact lenses. There are now several
disposable or planned replacement versions of soft lenses for astigmatism.
They work extremely well and are very convenient. There are even tinted versions
of soft contact lenses for astigmatism that can enhance a light colored eye
or change the color of a darker eye. They are not yet available in disposable
form.
Pediatric Contact Lenses
Eye Consultants of Syracuse has been fitting pediatric contact lenses for
over twenty years. For children born with congenital cataracts, special,
rigid, oxygen permeable lenses or silicon soft lenses are inserted after
surgery to correct the child’s vision. Parents are instructed on how to insert,
remove and properly care for the contact lenses.
Tinted Contact Lenses
Soft, tinted contact lenses are available in several different colors and
designs and some are tinted to enhance light colored eyes – for example,
making a blue eye darker or brighter blue.
You can also change darker colored eyes to different shades of blue, green,
violet or use hazel tinted lenses that will make a dark brown eye appear
lighter.
Recently, Wesley-Jessen has released their wild eyes collection of specialty
tinted lenses with several designs including, cats eye, eight ball, white
out and several other fun designs. Tinted lenses are even available for patients
who have astigmatisms.
Disposable Contact Lenses
Disposable contact lenses first became available in 1988 and have become
very popular with patients and contact lens practitioners alike. One-day
disposable lenses are thrown away every day after being worn. They are very
convenient because no solutions are required and are sometimes more comfortable
for patients sensitive to solutions.
Disposable lenses that are reused must be cleaned and disinfected properly.
There are currently bi-focal disposal lenses, tinted disposable lenses and
disposable lenses for astigmatism. As technology continues to improve, more
forms of disposable lenses will become available. Disposable contact lenses
are especially helpful to patients experiencing deposit problems with their
conventional lenses. Disposable lenses provide greater comfort and less chance
for eye irritation.
Prosthetic Tinted Contact Lenses
Eye injuries can cause scarring of the cornea or may cause parts of the iris
to be missing. Specialty tinted lenses are available to cover scars or create
an artificial iris. This can create a cosmetically pleasing eye and reduce
glare. For patients born with congenital defects of their corneas, specialty,
tinted contact lenses can cover these defects. They are available in prescription
form, including strong prescriptions and in prescriptions for astigmatism.
Extended Wear Contact Lenses
Extended wear lenses have been available since the early 1980’s, however
they experienced some negative publicity due to the risk of serious infections.
There is now, however, a new generation of extended wear contact lens materials
that have generated renewed interest. New materials available in soft and
rigid oxygen permeable lens designs allow a much higher amount of oxygen
to get to the cornea, making extended wear a safer alternative than in the
past.
Oxygen Permeable Contact Lenses
Rigid oxygen permeable lenses provide excellent vision in almost any prescription.
They correct astigmatism extremely well and are available in custom designs
for people with unusual prescriptions and bi-focals. The technology and materials
have improved over the years and today’s rigid oxygen permeable lenses are
extremely oxygen permeable, comfortable and less likely to cause an infection.
Keratoconus
Keratoconus is a condition of the eye in which the normally round shape of
the cornea is distorted and a cone shaped bulge develops, causing visual
impairment but rarely complete loss of sight. The first signs of keratoconus
are blurry and distorted vision. In the early stages of the disorder, eyeglasses
may help but as the disorder progresses, contact lenses must be utilized
to achieve best visual acuity.
Rigid oxygen permeable lenses are the lenses of choice for keratoconus patients,
providing good vision and high oxygen permeability. The lenses are easy to
handle and are available in custom designs.
Due to recent advancements in lens manufacturing technologies, contact lens
designs now deliver better lens comfort and vision. New designs are continually
on the horizon as technology continues to improve.
