Keratoconus and other corneal irregularities cause the front of the eye to become uneven, making glasses and regular contacts ineffective. Scleral lenses and custom soft lenses create a smooth surface over the cornea, allowing light to focus properly and restoring clear vision.


LASIK, PRK, and other eye surgeries can sometimes leave the cornea with an irregular shape. If you are experiencing blurry vision, glare, or halos after a procedure, specialty contact lenses can often provide the clarity that glasses cannot achieve.
Radial keratotomy (RK) was a popular vision correction surgery in the 1980s and 1990s. Many RK patients now experience fluctuating vision and difficulty with standard contacts. Scleral lenses can vault over the corneal incisions and provide stable, comfortable vision throughout the day.
Conditions like keratoconus, pellucid marginal degeneration, corneal scarring, high astigmatism, and complications from LASIK or radial keratotomy may require medically necessary contact lenses. These lenses help when standard glasses or contacts cannot provide clear vision.
Options include scleral lenses, custom soft lenses like KeraSoft IC and NovaKone, hybrid lenses, gas permeable lenses, and specialized prosthetic lenses. The right choice depends on your specific eye condition and visual needs.
Scleral lenses vault over the entire cornea and rest on the white part of the eye. This creates a smooth optical surface over irregular corneas and holds a layer of fluid that keeps the eye hydrated. They can provide clear, comfortable vision for many challenging conditions.
