What are Scleral Contact Lenses?
Scleral lenses are very large diameter gas-permeable lenses ranging from 14mm to 20mm that completely vault the cornea, “land” and rest on the white part of the eye called the sclera, and create a reservoir of tears.

Because of the lens size and this tear reservoir, they are typically extremely comfortable and at times may provide better vision correction than other standard contact lenses, glasses, and even surgery.

The lenses are made of materials that let oxygen pass through the lens and provide a thin cushion of fluid that stays between the lens and eye that makes them very comfortable, reduces redness and creates a healthy environment for the eye.The lens is appropriate for most prescriptions and is available for patients who need help reading (multifocal / bifocal) and those with astigmatism (torics).

Frequently Asked Questions About Scleral Contact Lenses

How long can I wear scleral contact lenses during the day?

Many patients are able to wear them all day long (about 12-14 hours).  Some people may need to remove the lenses once per day to rinse them and then reinsert the lenses in order to maintain the best vision and comfort possible.

Can I wear scleral lenses if I have dry eyes.

In most cases yes.  In fact, scleral contact lenses are often a way to treat dry eyes because the lens maintains a pool of saline between the lens and the eye.  This pool constantly bathes the cornea with liquid throughout the day, improving symptoms of dry eyes.

How long due scleral contact lenses last?

The are not disposable lenses.  They are made from a durable material that usually last between 1-3 years, about the same time as a regular gas permeable lens.
