There are a lot of people suffering from various eye conditions, but many aren’t good candidates for using contact lenses or have difficulties wearing contact lenses. The large diameter gas permeable (GP) lenses known as scleral lenses are an effective alternative for such patients as they can provide the same benefits that conventional GP lenses can give.
Vision problems caused by Keratoconus and other cornea irregularities can be corrected by the smooth optical surface of the scleral lens. Scleral lenses are filled with isotonic fluid before fixing, so that the space between the cornea and the back surface of the lenses acts as a tear reservoir. This tear reservoir continually provides moisture and oxygen to prevent eye injuries like corneal abrasions.
Why Scleral Lenses are a Better Option?
The key advantages of scleral lenses are that it provides sharper vision, greater durability, easier handling and less risk of complications compared to standard lenses. With BostonSight Scleral lenses it is easy to custom design a lens to provide the best possible vision, eye health and comfort for each patient. Scleral lenses vault over the entire corneal surface and rest on the sclera of the eyes while the conventional GP lenses cover only a portion of the cornea. Scleral lenses are more stable on the eyes because of its larger size so there is less chances of getting accidentally dislodged from the eye. This also makes scleral lenses more comfortable especially for sensitive eyes or irregularly shaped corneas. In addition to correcting your vision, scleral lenses also help improve the health of your eyes and to reduce the need for surgical intervention for those with severe ocular surface diseases.
Types of Scleral Lenses
Scleral lenses come in three different categories, differentiated by their size running from 14.5mm to 24mm and the primary contact it has with the front surface of the eye. The larger size allows it to cover the entire cornea, extending to the sclera. During the contact lens exam, your eye specialist will decide which size of contact lens to use depending on the complexity of the vision problem.
Corneo-scleral and semi–scleral lenses
Much larger than GP lenses, Corneo-scleral and semi-scleral lenses are designed to rest near the junction between the cornea and the sclera. Patients who require contacts after laser eye surgery or corneal refractive surgery can benefit from this type of scleral lens to correct irregular astigmatism.
Mini scleral lenses
Mini scleral lenses are large diameter rigid lenses designed to bind over the entire corneal surface and rest on the anterior sclera. Patients whose corneal shape is distorted by eye conditions, scarring or after a corneal graft procedure can get their vision rehabilitated by using this type of scleral lens.
Full scleral lenses
The largest of all scleral lenses, full scleral lenses provide the most amount of clearance between the back surface of the lean and the cornea. Patients who suffer from complex eye conditions like advanced keratoconus, severe dry eyes or severe ocular disease can benefit from using the full scleral lens.
With lens materials that are highly breathable rigid gas permeable, all types of scleral lenses keep the eyes healthy and comfortable by supplying plenty of oxygen to the front surface even though the entire cornea is covered.
