What are Scleral Lenses?
Scleral contact lenses are large-diameter lenses that provide clear and comfortable vision because the lenses do not actually touch the cornea. Instead, scleral lenses vault over the entire corneal surface, resting on the “white” portion of the eye known as the “sclera.” The space between the back and front portions of the scleral lens is filled with unpreserved sterile saline solution, which means that the eye always remains in a liquid environment. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area.
These larger lenses also are more stable than conventional gas permeable contact lenses, which move with each blink because they cover only a portion of the cornea. Moreover, scleral lenses do not fall out, bits of grit do not lodge behind them during wear, and they are surprisingly comfortable to wear when fitted properly.
There are three different types of scleral lenses:
Corneo-Scleral Lenses & Semi-Scleral Lenses
Larger than conventional GP lenses; sit near the junction between the sclera and the cornea
Vault over the entire corneal surface and sit on the anterior sclera
Full Scleral Lenses
Largest scleral lenses; provide greatest amount of clearance between the cornea and back surface of the lens
Scleral lenses are typically manufactured with highly breathable, rigid gas permeable lens materials. Thus, even though the lenses cover the entire corneal surface, they allow plenty of oxygen to reach the front surface of the eye to maintain health and comfort.
