Corneal Refractive Therapy (CRT)
Corneal refractive therapy provides a
reshaping of the cornea to correct near-sightedness. These specially designed contact lenses lenses are worn overnight
and removed upon awakening thus allowing the patient to be free contact lenses or spectacles throughout
the daytime hours. Often patients are able to maintain good vision by sleeping in the lenses as little as 2-3 days per
week. Call to schedule an appointment to see if you would be a good candidate.
Rigid Gas Permeable (RGP's)
Gas permeable contact lenses are rigid lenses made of durable plastic that
transmit oxygen. These lenses are small and cover only a portion of the cornea. Though they are less popular than
soft lenses, gas permeable contacts are a great choice for some patients. They are very durable and typically provide
very crisp vision. These contacts can be used to correct myopia, hyperopia, astigmatism and presbyopia and are often
worn by patients who have keratoconus.
Soft Contact Lenses
These
contact lenses are made from gel-like, water-containing plastics called hydrogels, and cover the entire cornea. Because
of the material, soft lenses are typically more comfortable when
you first insert them into your eyes. Many soft lenses are disposable, so you can throw them away after using them for a short
time. Like RGP's, soft lenses can correct myopia, hyperopia, astigmatism and presbyopia. New types of soft
lenses continue to come to market as new technologies develop.
