If you are looking to wear contact lenses but have always had problems with comfort or have been told you'll never be able to wear contact lenses because of an irregularly shaped cornea or other eye problem, it may be time to look into a type of contact lens known as a “scleral lens.”
Scleral contact lenses are large diameter rigid gas permeable contact lenses designed to pass over the cornea entirely, resting comfortably on the white of your eye, also known as the sclera. This allows scleral lenses to essentially replace the irregular surface of the cornea with a perfectly formed optical surface, giving you the kind of perfectly crisp vision you may not even be able to accomplish at all with eyeglasses or other forms of vision correction. This extra area also allows the lens to be a liquid reservoir to provide extra comfort for those who otherwise may have comfort issues with regular contact lenses.
Scleral lenses are noticeably larger than normal gas permeable lenses. The size of the scleral lens that a person needs is often determined by how complex their eye condition is. Mild Keratoconus and abnormal astigmatism are usually considered less complicated and tend to require smaller scleral lenses, whereas more advanced cases of keratoconus, severe and chronic dry eyes or advanced ocular diseases often are considered more complicated to treat, and usually require larger scleral lenses.
Scleral lenses are always custom made to fit the unique contours of your eye, so fitting of this type of specialty lens requires a specific expertise and a greater amount of fitting time than with standard gas permeable and soft contact lenses. In many cases, a digital map of your cornea will by created, displaying for your optometrist an image referred to as your “corneal topography.”
This will help your eye doctor more easily find the right fit for you, and reduce the number of trial pairs and the amount of time spent in fitting.
Because of the increased amount of time that is required to obtain a corneal topography and customize a scleral lens that works best and is most comfortable for your eyes, as well as the larger material cost to produce, scleral lenses can be significantly more expensive than traditional gas permeable and soft contact lenses. Despite this, scleral lenses still remain the most comfortable and, in many cases, the only way, to obtain comfortable, accurate vision for those suffering from:
- Severe Dry Eye Disease
- Post Corneal Transplant
- Post RK Surgery
- Post Laser Refractive Surgery
- and other similar eye conditions or cornea irregularities

Read What Our Patients Say...
I have significant keratoconus and Dr. Sobel was recommended to me for scleral lenses. Dr. Sobel worked tirelessly to fine tune my fit and vision over several visits to get my vision just right. I would recommend Dr. Sobel to anyone with KC, or any other vision issues, without hesitation.
I am wearing Sceral Lens for five years and I have tried many doctors to get the fitting for sceral lens. I only liked only two of them and he is top of the list.
Dr. Sobel is the best keratoconus scleral lens eye doctor in the state. I have had keratoconus for 7 years and have always had to settle for lenses that didn’t fit well and caused pain daily.
After working with Dr. Sobel starting last year he was able to get me into a pair of scleral lenses that fit great and are pain free. I would highly recommend Dr. Sobel to every keratoconus patient.
Dr. Sobel and his staff are excellent. He fitted me for hard contact lenses for keratoconus and was incredibly kind, patient and informative throughout. He and his staff also worked with my insurance company to minimize cost. Highly recommended.
My scleral lens are a fabulous fit. Dr. took his time and made sure of my comfort and vision. No more night glare and the lens are super comfortable.
