Scleral contact lenses are large-diameter, rigid gas permeable lenses that vault completely over the cornea and rest on the sclera, the white part of the eye. A reservoir of preservative-free saline fills the space between the lens and the corneal surface, keeping the eye hydrated and creating a smooth optical surface. For patients in Las Vegas dealing with hard-to-fit eyes, corneal irregularities, or chronic dry eye, scleral lenses can be a life-changing option.
Keratoconus is a progressive condition in which the cornea thins and bulges into a cone-like shape. This irregular surface distorts vision in ways that glasses and soft contact lenses cannot fully correct. Scleral lenses bridge over the cone without pressing on the cornea, replacing the irregular surface with the smooth front curve of the lens. The result is sharper, more stable vision with significantly improved comfort compared to smaller rigid lenses that rest directly on the corneal surface.
Patients with irregularly shaped corneas, whether from conditions like keratoconus or pellucid marginal degeneration, complications following refractive surgery, or a corneal transplant, often find that glasses and soft contact lenses leave them with blurry or fluctuating vision. Scleral lenses are custom-designed from detailed corneal and scleral measurements, so they can accommodate virtually any corneal shape while delivering clear, consistent optics.
Yes. The saline reservoir that sits between a scleral lens and the cornea acts as a continuous moisture bath throughout the day. This fluid layer protects the corneal surface from exposure and friction, making scleral lenses particularly beneficial for patients with moderate to severe dry eye, Sjogren’s syndrome, or graft-versus-host disease. Many dry eye patients who could not tolerate soft contact lenses find that scleral lenses are comfortable enough for all-day wear.
Because of their large diameter, scleral lenses center well on the eye and move very little with blinking. This stability means your vision stays consistent whether you are reading, driving, or working on a computer. The lenses are also far less likely to dislodge during physical activity, making them a practical choice for athletes and patients with active lifestyles.
The large optic zone of a scleral lens provides a broader area of corrected vision compared to smaller gas permeable or soft lenses. Patients often notice improved peripheral clarity and reduced glare, especially in low-light conditions or when driving at night.
Scleral lenses physically shield the corneal surface from wind, dust, pollen, and other airborne irritants. This barrier effect is helpful for patients with environmental allergies or those who work in dusty or windy conditions. The protective layer can also benefit patients recovering from certain corneal procedures.
Scleral lenses are made from durable, high-oxygen-permeable rigid materials that typically last one to two years with proper care. While the initial cost is higher than disposable soft lenses, the extended replacement cycle often makes sclerals more cost-effective over time. Some vision insurance plans and medical insurance may cover scleral lenses when they are prescribed for a documented corneal condition. FSA and HSA funds can also be applied toward the cost.
Scleral lenses are worth considering if you experience any of the following:
A comprehensive scleral lens evaluation, including corneal topography and scleral mapping, is the best way to determine whether these lenses are a good fit for your eyes and your lifestyle.
