Scleral lenses are a type of gas-permeable contact lens that are larger than conventional contact lenses. Unlike regular contacts that rest on the cornea, scleral lenses sit on the white part of the eye, known as the sclera. This design makes them uniquely beneficial for certain eye conditions.
What are Scleral Lenses?
Scleral lenses are large-diameter gas-permeable contact lenses uniquely designed to vault over the entire corneal surface and rest on the 'white' part of the eye (sclera). By doing so, scleral lenses create a smooth optical surface to correct vision problems caused by irregular corneas.
The unique design of scleral lenses provides several advantages over standard contact lenses. For one, their size makes them more stable on the eye, less likely to dislodge, and more comfortable for people with sensitive or irregular corneas. Secondly, the space between the cornea and the lens can hold a reservoir of fluid to provide constant hydration for dry eyes.
Who Can Benefit from Scleral Lenses?
Scleral lenses can benefit a wide range of individuals. They are particularly beneficial for those who have irregular corneas, dry eyes, or severe allergies. Additionally, people who are unsatisfied with their vision using standard contact lenses or glasses may also find scleral lenses a better option.
For individuals with irregular corneas due to conditions like keratoconus or post-LASIK complications, scleral lenses can provide excellent vision correction. They can also be beneficial for those with severe dry eye syndrome, as the lens' design provides constant hydration.
Eye Conditions that Can be Treated with Scleral Lenses
Scleral lenses can be used to treat a variety of eye conditions. These include keratoconus, pellucid marginal degeneration, post-refractive surgery (like LASIK), ectasia, severe dry eye syndrome, and other corneal irregularities or distortions.
Keratoconus is a condition where the cornea thins and bulges into a cone-like shape, causing blurred and distorted vision. Scleral lenses can help by providing a smooth, regular surface for light to enter the eye.
Similarly, for post-LASIK complications, where the cornea may become irregular, scleral lenses can provide improved vision. They can also offer relief for those with severe dry eye syndrome by providing a constant reservoir of fluid to hydrate the eyes.
The Benefits of Using Scleral Lenses
The benefits of using scleral lenses are numerous. They offer improved vision for those with corneal irregularities, increased comfort for those with dry eyes or sensitive corneas, and they are more stable and less likely to dislodge than standard contact lenses.
Additionally, because scleral lenses are custom-made to fit each individual's eye, they can offer superior vision correction. Individuals often report that their vision with scleral lenses is clearer and sharper than with glasses or regular contact lenses.
Are Scleral Lenses Right for You?
Scleral lenses are a powerful tool that offer a viable solution for those with corneal irregularities, dry eyes, and other eye conditions that cannot be adequately managed with standard contact lenses or glasses. With their unique design and the advanced technology behind them, scleral lenses provide both comfort and superior vision correction.
