Keratoconus/Scleral Lenses

Scleral lenses provide vision quality that glasses and soft contacts simply cannot match for irregular corneas. The liquid reservoir between the lens and cornea creates a perfectly smooth optical surface, eliminating the distortions, ghosting, and halos that make reading, driving, and recognizing faces difficult with keratoconus. Most patients experience immediate improvement in vision sharpness and report seeing details they haven’t noticed in years, restoring confidence in performing work tasks and enjoying activities they’d previously avoided.

While scleral lenses appear large, they’re remarkably comfortable because they rest on the less-sensitive sclera rather than your cornea. The fluid-filled space cushions your eye throughout wear, and the lens edge tucks under your eyelids rather than rubbing against them with each blink. Many wearers report forgetting they’re even wearing lenses after the initial adjustment period, enjoying stable vision that doesn’t shift or rotate throughout the day like traditional gas-permeable contacts often do.

The saline reservoir between the lens and cornea provides constant moisture to your eye’s surface, making scleral lenses an excellent solution for severe dry eye disease. This protective fluid layer shields your cornea from environmental irritants like wind, dust, and dry air while maintaining optimal hydration throughout the day. Patients with conditions like Sjögren’s syndrome, graft-versus-host disease, or post-LASIK dry eyes often find that scleral lenses provide relief when drops and medications have failed.

Unlike soft lenses that can rotate on your eye or smaller rigid lenses that can dislodge, scleral lenses remain stable and centered throughout daily activities. This stability means consistent, reliable vision whether you’re looking up, down, or side to side, with no blurring or visual fluctuations requiring constant repositioning. The larger diameter prevents lenses from popping out during physical activity, giving you freedom to exercise, play sports, and live actively without worrying about lens displacement.

While not a cure, scleral lenses may help slow keratoconus progression by reducing corneal trauma from eye rubbing—a behavior many keratoconus patients develop in response to visual distortion and irritation. The protective vault created by scleral lenses prevents mechanical contact with the fragile corneal surface, potentially reducing inflammation and stress that can accelerate cone development. Combined with proper keratoconus management and regular monitoring, scleral lenses become part of a comprehensive strategy for preserving your vision long-term.

Keratoconus cannot be cured, but its progression can be slowed or halted through various treatments, including corneal cross-linking, which strengthens corneal tissue to prevent further bulging. Scleral lenses don’t cure the underlying condition but provide exceptional vision correction by creating a smooth optical surface over the irregular cornea. Most patients with keratoconus successfully manage their condition through a combination of proper medical monitoring, avoiding eye rubbing, and wearing appropriate vision correction, like scleral lenses.

Keratoconus rarely causes complete blindness, though advanced cases can severely impair vision quality and make daily activities extremely difficult without proper correction. Most people with keratoconus maintain functional vision through glasses in early stages, then progress to specialty contact lenses like sclerals as the condition advances. In severe cases where the cornea becomes scarred or extremely thin, corneal transplant surgery may be necessary, but even these patients typically retain useful vision with proper treatment and follow-up care.

A scleral lens is a large-diameter rigid gas-permeable contact lens that vaults completely over your cornea and rests on the white part of your eye called the sclera. The space between the lens and your corneal surface fills with preservative-free saline solution, creating a smooth refractive surface that corrects vision while protecting and moisturizing your eye. These lenses are custom-designed based on precise measurements of your eye’s unique shape and are particularly effective for keratoconus, post-surgical corneas, severe dry eyes, and other conditions causing irregular corneal surfaces.

Scleral lenses typically last one to three years with proper care and handling, though replacement timing depends on factors like deposit buildup, scratches, protein accumulation, and changes in your prescription or corneal shape. Some patients need annual replacements while others wear lenses successfully for two years or longer before vision quality or comfort begins declining. Regular follow-up appointments help us monitor lens condition and determine optimal replacement timing, ensuring you always have lenses providing maximum vision correction and comfort.

Your scleral lens prescription includes multiple parameters beyond simple power correction, specifying lens diameter, base curve radius, peripheral curve design, and vault depth needed to properly fit your eye’s unique shape. The power component corrects your refractive error just like glasses, while other measurements ensure the lens properly vaults over your cornea without touching it, maintains proper alignment, and allows healthy tear exchange beneath the lens. These complex specifications require specialized fitting expertise, which is why scleral lenses must be custom-ordered rather than purchased off-the-shelf like standard soft contacts.
