yecare professionals aren't easy to please, and the fact
that many recommend GP contacts to their
patients speaks highly of the benefits of these high-tech lenses. Read what they have to
say:

GP contacts
(also called RGP lenses) are currently one of the best visual and
healthiest options available to a patient considering contact lenses. They promote
excellent optical quality for the appropriate candidates, especially those with corneal astigmatism.
Because of their polymer structure and chemistry, GP contact lenses
resist protein and bacterial buildup and therefore promote long-term contact
lens wearing success. Some GP materials currently provide the highest oxygen permeability
to the cornea compared with any soft lens product available in the United States. Because
of their design, they flush trapped particles and bacteria quickly to maintain a healthy
ocular surface.
Finally, they are economically smart, because the material does not readily
tear, dehydrate, or spoil due to improper care and treatment, thus allowing safe contact
lens wear without weekly or monthly scheduled lens replacement.
I recommend GP contact lenses to almost all patients, but the following
are especially good candidates:
Patients with
Corneal Astigmatism Although it is the most common type, not all patients
have corneal astigmatism, because some astigmatism can form inside the eye as well. Ask
your doctor if your astigmatism is "corneal" or on the front of the eye. This
means that your cornea is shaped more oblong like a football, rather than round like a
baseball. GP contact lenses correct corneal astigmatism easily by "masking" the
oblong cornea and providing a surface that optically performs like a spherical cornea.
Teenagers
Studies are being performed in the U.S. and around the world to examine the effects of
GP contact lenses to slow the progression of myopia
(nearsightedness). Although no conclusions have been drawn, the potential to limit or slow
the progression of myopia is a benefit to my teenage patients, who are always offered this
form of contact lens correction.
Extended Wear
Because of the tremendously high oxygen permeability available in some GP
materials, they currently make the safest lens for extended
wear. Coupled with lens designs that promote tear exchange and remove trapped debris,
GP contact lenses worn for extended wear have the lowest rates of extended-wear
induced complications.
Corneal Distortion
Many patients with corneal disease, warpage, or irregularity can benefit only from
GP contact lenses to smooth out the front surface of the eye for appropriate
refraction of light. Examples include: keratoconus, corneal
transplants, refractive surgery, corneal trauma, and
warpage. Visual quality can be improved dramatically with GP contact lenses,
compared with soft lenses or spectacles, and many patients depend on them to function
visually.

GP contact lenses offer
patients a unique opportunity for optimum visual acuity, excellent comfort, and the
healthiest contact lens system. Using oxygen permeable materials allows your contact lens
practictioner to fit designs that can help almost all types of problems, including
nearsightedness, farsightedness, astigmatism, bifocal and multifocal needs, and diseases of the cornea,
including keratoconus. These lenses have also demonstrated an advantage in retarding
myopic (nearsighted) progression.
The fitting of GP contact lenses requires accurate
technical skills to ensure precision. The invention of new materials and the fabrication
of these lenses have utilized space age technology.
If you have failed with previous contacts, it is time to
reconsider GP contact lenses as an option for success.
