What is a scleral lens?
Scleral lens is a type of contact lens. The lens is much larger than the typical contact lenses that many people today wear. Unlike the typical contact lens, which rests on the cornea of the eye, the sclerus lens is on the cornea and on the eye glass. While the cornea lens can measure about 0.35 inches (9.0 mm) up to about 0.37 inches (9.5 mm), a full sclerálová lens can measure up to about 0.94 inches (24.0 mm), which is about a quarter of the United States. Sclerral lenses allow people with certain eye conditions to find out when traditional remedial methods and eye treatment failed.
The scleral lens was actually the first contact lens to be invented, dating back to 1888. The German glass manufacturer suggested an enlarged lens from the glass to help him with his vision problems. The lenses were serious, uncomfortable and deprived the eye of the oxygen, so the idea of the scleral lens disappeared. In the 1950s, gas permeable, plastic polymer as developed Rneal lenses, and they became primary contactlenses for most bearers. Unfortunately, some people cannot wear typical correction corneal lenses. Those with breaking, thinning, irregularly shaped or damaged cornea cannot wear typical contact lenses. Since scleral contacts do not rest on the cornea, but on the glass or white part of the eyeball, the result is better vision and improved comfort.
scleral lenses allowed patients suffering from keratoconus, corneal surgery and other eye diseases. The unique lens does not touch the cornea of the eye, but rather floats above it and grabs the scler for support. In order to avoid drying or irritation of the eye, the lens is filled with a sterile physiological liquid before inserting into the eye. People who wear scleral contacts mention improved comfort and improved vision, as lentils do not touch sensitive cornea to cause irritation.
Each scleral lens is tailored to namontuned for every eye for each patient. The patient is first strictly tested for all existing and basic eye diseases. The initial test lens and assembly are planned before ordering and mounting the final product. Patients may find that inserting a glass lens is in fact easier than inserting a small corneal lens and the sclerus lens is less likely to emerge from the eye. As with corneal lenses, sclerous contacts are made from gas permeable plastic material and must be replaced regularly.
