Most people think of glasses, soft contacts, cataract treatment, or glaucoma management when talking about eye care. But for patients with complex corneal conditions or severe dry eye, traditional options simply aren’t enough. Scleral lenses offer a breakthrough solution, providing remarkable clarity and comfort for people who have struggled with regular contacts or persistent irritation.
At Tennessee Eye Care, we use advanced diagnostic tools and specialized fitting techniques to help patients across Knoxville, Harriman, Lenoir City, Morristown, and Powell experience the benefits of these unique lenses. Below are seven key facts that explain how scleral lenses work and why they have become a life-changing option for many.
Scleral lenses are large-diameter gas-permeable contact lenses designed to vault over the cornea and rest gently on the sclera—the white part of the eye. By creating a smooth optical surface, they provide crisp, stable vision and exceptional comfort.
Keratoconus causes the cornea to thin and bulge into a cone shape, making standard contacts uncomfortable or impossible to wear. Scleral lenses completely bypass this irregular surface. The lens vaults over the cornea and fills the space with sterile saline, creating a liquid cushion that protects the eye and improves vision dramatically.
Patients with chronic dry eye often find immediate comfort with scleral lenses. The fluid reservoir between the lens and the cornea keeps the eye surface continuously hydrated, relieving burning, irritation, and painful dryness throughout the day.
A scleral lens fitting requires a highly detailed eye exam in Tennessee, often including corneal topography. This imaging maps every contour of your cornea, allowing for precise customization.
During the fitting, a specialty contact lens provider—or in some cases, a glaucoma specialist in Tennessee who manages complex conditions—tests different trial lenses to find the ideal vault and curvature. This ensures the lens fits comfortably without touching the sensitive cornea.
Because scleral lenses rest on the sclera rather than the cornea, they stay stable throughout the day and rarely shift with blinking or movement. This stability makes them ideal for active patients. Their design also avoids the irritation that many people experience with regular contacts, making scleral lenses surprisingly comfortable even for those who couldn’t tolerate other options.
Scleral lenses are used for more than keratoconus or dry eye. They are also highly effective for patients with:
In many cases, they provide the clearest and most comfortable vision possible.
Because scleral lenses require advanced fitting and monitoring, they are typically prescribed by eye doctors with specialized training in complex contacts. Some glaucoma specialists in Tennessee also fit scleral lenses for patients with complicated corneal conditions, ensuring both the underlying disease and the lens fit are properly managed.
Scleral lenses represent one of the most powerful advancements in specialty vision correction. While they don’t treat the different types of glaucoma, they offer life-changing benefits for patients with keratoconus, severe dry eye, or other corneal disorders. If traditional contacts or glasses haven’t worked for you, a specialized eye exam in Tennessee can determine whether scleral lenses are the solution for clearer, more comfortable vision.

Because of their size, scleral lenses require a specific technique and a small insertion tool. During your specialized fitting, we teach you the process step-by-step. Most patients adapt quickly.
Yes. Scleral lenses can be customized with your exact distance and near prescription, offering clear, tailored vision similar to traditional contacts.
No. Scleral lenses are designed for corneal conditions and dry eye relief. Treatment for the different types of glaucoma requires drops, laser procedures, or surgery, typically managed by a glaucoma specialist in Tennessee.
