Scleral Lenses

Custom Fitted Scleral Lenses

At Vue Vision Centre, we take pride in fitting complex corneas. Our highest rate of success for fitting Keratoconus and other irregular cornea patients has come with scleral lenses. These lenses give vision and comfort not possible with a conventional rigid lens or piggyback designs. We take topographical maps of the exact irregularities and then custom design a lens that provides the ideal correction. Because of the way these lenses are fit, they can optically correct the distortion from diseased corneas, providing stable vision in the majority of cases!

Scleral lenses

Scleral lenses are large diameter rigid lenses that sit on the white part of the eye and vault over the irregularities in the cornea. This enables them to provide good vision and excellent comfort. We are always on the leading edge of technological advancements and fit many different types of scleral lenses including multifocals. Scleral lenses can be customized for any type of prescription. Many patients who have never been able to see well with glasses get stable vision with sclerals. We also fit specialty gas permeable lenses such as Rose-K, piggyback and other post-surgical designs for mild to moderate cases.

Scleral lenses are much larger than Conventional RGP Lenses which aids in stability on the eye and improved vision with irregular corneas. They also provide initial comfort on instillation similar to soft lenses.

Types of Scleral Lenses

There are three categories of scleral lenses, based on size and where the lenses have their primary contact with the front surface of the eye.

Corneo-scleral lenses and semi-scleral lenses

Much larger than typical GP lenses and rest right by the junction between the cornea and the sclera.

Mini-scleral lenses

Vault over the whole corneal surface and rest on the anterior sclera.

Full scleral lenses

The biggest in size and offer the most clearance between the back of the lens and the cornea.

Are you a Candidate for Scleral Lenses?

Generally, anyone interested in achieving the best vision possible with contact lenses can be a candidate for scleral lenses. But scleral GP lenses are particularly helpful for the following:

Irregular corneas

Vision problems caused by an irregularly shaped cornea: whether naturally occurring, due to an eye condition such as keratoconus, or resulting from eye surgery: typically, cannot be fully corrected with glasses or soft contact lenses. Scleral lenses typically will provide sharper vision for these eyes.

Hard-to-fit eyes

If your eyes cannot be comfortably fitted with conventional GP lenses or the shape of your eye causes the lenses to dislodge too easily from your eyes (during sports, for example), scleral lenses can provide a more comfortable and secure fit.

Dry eyes

If your eyes are too dry for conventional contact lenses, scleral lenses can help. In particular, the space created between the back surface of full scleral lenses and the cornea acts as a tear reservoir to keep the front of your eye moister and more comfortable.

Cost of Scleral Lenses

Scleral lenses are custom-made to the exact specifications prescribed by our eye doctors to provide the best possible vision, eye health and comfort. Also, special automated measuring tools and imaging devices are used to fit scleral lenses, and these instruments typically are not required for fitting soft lenses. For these reasons, professional fees associated with fitting scleral lenses and lens replacement costs are much higher for scleral lenses than other contact lenses. Our doctors will discuss with you the specific costs for your individual needs. In some cases, vision insurance may cover a portion of the costs associated with scleral lenses.

If you have been fit with these lenses or would like to know more about whether you are a candidate for scleral lenses please contact us at 519-497-0309 and book a fitting consultation. It would be our privilege to improve your sight and quality of life with custom fitted scleral contact lenses.
