The Benefits of Scleral Lenses for Keratoconus

Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone-like shape. This irregular shape can distort vision, making daily tasks like reading, driving, and using a computer more challenging. While glasses and traditional contact lenses may help in the early stages, many patients find that their vision needs change over time. For those with moderate to advanced keratoconus, scleral lenses can offer a remarkable solution.

What Are Scleral Lenses?

Scleral lenses are large-diameter gas-permeable contact lenses designed to vault over the cornea and rest on the white part of the eye (the sclera). They create a smooth optical surface and hold a tear-filled reservoir between the lens and the cornea, which helps improve vision and comfort.

How Scleral Lenses Help with Keratoconus

Because keratoconus causes the cornea to become irregular in shape, traditional soft contact lenses may not sit evenly on the eye, leading to blurred vision or discomfort. Scleral lenses bypass these issues by completely covering the cornea’s irregular surface, providing a consistent refractive surface for light to enter the eye. This results in sharper, clearer vision.

Key Benefits of Scleral Lenses for Keratoconus

Scleral lenses create a smooth optical surface that can significantly improve visual clarity, even for individuals with advanced corneal irregularities. By vaulting over the irregular cornea and providing a consistent refractive surface, they allow light to enter the eye more effectively, resulting in sharper, clearer vision.

These lenses are also known for their enhanced comfort. Unlike smaller rigid lenses that rest directly on the cornea, scleral lenses sit on the less sensitive sclera. This positioning reduces irritation and allows many patients to comfortably wear them for extended periods.

Another advantage is the protection they offer for the cornea. The tear-filled reservoir beneath the lens keeps the cornea hydrated throughout the day, which helps reduce dryness and shields sensitive corneal tissue from further irritation or damage.

Scleral lenses also provide exceptional stability. Their larger size helps them remain securely in place, making them less likely to shift or fall out during normal daily activities. This stability is especially beneficial for patients with active lifestyles.

Finally, each scleral lens is custom-designed to fit the unique shape of the patient’s eye. This personalized approach ensures optimal vision correction, maximum comfort, and a secure fit tailored to individual needs.
