Scleral Lenses
Understanding Scleral Lenses
Scleral lenses are a specially designed type of contact lens used to correct vision and/or restore the ocular surface, often when other treatments are not effective. Patients who have irregular corneas, high prescriptions, dry eye or other conditions, often see much improved vision with scleral lenses. Patients who cannot obtain good vision or comfort with glasses or conventional contact lenses can benefit from using scleral lenses. Though scleral lenses began as a specialty treatment, they have become an increasingly popular choice in recent years even for people who have normal corneas.
Each scleral contact lens is custom-made for the patient.
The lenses need to be fitted to vault over the cornea to maintain a constant reservoir of fluid between the lens and cornea. This design ensures the eye remains hydrated during the entire time the lens is worn. In addition, the fluid layer helps compensate for any irregularities in the shape of the cornea, which improves vision.
At the Family Eye Center, we specialize in fitting scleral lenses. Our scleral lenses are highly permeable to oxygen and provide the comfort of a soft lens while achieving the higher optical quality of a rigid gas permeable lens . In most cases, patients report no sensation or awareness of the lens while wearing it. The all-day comfort of scleral lenses is one reason for their increased popularity.
