Keratoconus
A custom lens can help neutralize distortion from an irregular corneal shape.

Specialty contact lenses
A smoother surface for clearer vision.
Scleral lenses vault over the cornea and rest on the white of the eye, creating a stable optical surface for eyes that need more than a standard contact lens.
Designed forComplex corneas
Severe dry eye
The fluid reservoir beneath the lens may support comfort throughout the day.
Post-surgical vision
Specialty optics can address fluctuations, glare, halos, and ghosting after corneal surgery.
01
How they work
The lens does not sit on the cornea.
Unlike a conventional contact lens, a scleral lens arches over the sensitive corneal surface. The space beneath it is filled with preservative-free saline, while the larger lens diameter creates a stable fit.
02
Your evaluation
Measured, mapped, and refined.
Dr. Nim evaluates the health and shape of your eyes using specialized technology such as the Pentacam, Corneal Scleral Profilometer, and Ovitz Wavefront Analysis. These measurements help guide diagnostic lens selection before vision, comfort, clearance, and edge alignment are refined for your individualized design.

What to bring
Help us understand your current vision.
Bring your current glasses, contact lenses, lens cases, and any records that explain prior surgery or a corneal diagnosis. The clinic will tell you whether to stop wearing existing lenses before your evaluation.
Frequently asked questions
Are scleral lenses comfortable?
Yes. Although scleral lenses are larger than traditional contacts, they rest on the sclera, which has fewer nerve endings than the cornea. Most patients find them surprisingly comfortable after a brief adjustment period.
Can scleral lenses help dry eyes?
Yes. The fluid reservoir beneath the lens continuously bathes the cornea in preservative-free saline, making scleral lenses an excellent option for many patients with moderate to severe dry eye disease.
Can scleral lenses help keratoconus?
Absolutely. Scleral lenses are considered one of the most effective non-surgical treatments for keratoconus because they create a smooth optical surface over the irregular cornea, often providing significantly clearer vision than glasses or soft contact lenses.
Are scleral lenses covered by insurance?
Coverage varies depending on your medical diagnosis and insurance plan. Our team will review your benefits and discuss any available coverage before beginning treatment.
