Scleral contact lenses are an extra-large type of rigid gas permeable lenses. Unlike traditional contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface. They rest on the white part of your eye (your sclera). This creates a new optical surface over the distorted cornea. Moreover, a reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment – making it optimal for healing.
Due to their size, scleral lenses are more stable on the eye than conventional gas permeable lenses and are therefore less likely to accidentally dislodge from the eye. This stability makes them more comfortable, especially for sensitive eyes or irregularly shaped corneas. Moreover, all scleral lenses are made with highly breathable gas permeable material so that plenty of oxygen reaches the front of the eye, keeping it healthy and comfortable.
Their unique design makes scleral lenses among the most comfortable contacts around, providing excellent vision for people of all ages.
Candidates for Scleral Lenses
Those with an irregularly shaped cornea, whether due to natural causes, trauma, an eye condition such as keratoconus, or complications following surgery, tend to develop vision problems that cannot be fully corrected with soft contact lenses or gas permeable contact lenses. In these cases, the shape of their eye causes the lenses to dislodge easily. Scleral lenses provide a more comfortable, secure fit and improved vision over traditional contact lenses and glasses.
Scleral lenses are particularly useful for managing eye conditions such as:
Post corneal transplant
Post-refractive surgery (i.e. LASIK or PRK)
Corneal scar (i.e. post trauma)
If you are interested in seeing whether scleral lenses are right for you, make sure that the eye doctor you visit has the knowledge and experience required to correctly fit you for these specialty lenses. Scleral lenses require precise customization, and every patient’s case is unique in degrees of severity and corneal measurements. We welcome you to call our doctors to discuss your needs and assess whether scleral lenses are helpful for your eye condition
