Scleral Contact Lenses are oversized hard contacts that are used to help patients with corneal disorders (such as keratoconus) and many other eye diseases see more clearly and comfortably. These lenses are large enough to rest on the sclera of the eye (the white part) and extend over the cornea without touching it. Standard contact lenses sit directly on the cornea are much more uncomfortable when used by anyone with an irregularly shaped cornea and may cause excessive eye dryness. The sclera is much less sensitive compared to the cornea, making these contacts more comfortable for patients with eye issues, including dry eye and ocular surface disease.
Scleral Contact Lenses are customized to the shape of each eye. Precise corneal contour mapping is done using Optical Coherence Tomography (OCT) to ensure a proper fit of the lenses. There is a small gap between the lens and cornea. This gap is filled with a lens solution that acts as a liquid barrier and can help treat patients with severe dry eye issues.
Who is a good candidate for Scleral Lenses?
Scleral Contact Lenses can help provide more comfortable and clear vision for patients with normal vision as well as those with irregular corneas caused by the following:
- Corneal transplant

- Sjogren’s Syndrome
- Graft Versus Host Disease (GVHD)
- Stevens-Johnson Syndrome
- Neurotrophic Keratitis
How are Scleral Contact Lenses fitted?
During the initial exam, Dr. Ramsey will conduct a comprehensive health evaluation of your eyes and an OCT scan is done to map out the shape of your eyes. After that, training is conducted on the proper technique to insert and take out the lenses. Once the prescriptions for the lenses has been finalized, they are sent to the lab for production along with your custom eye measurements. Our Scleral Contact Lenses are usually available for pick-up within one week.
A follow-up appointment is made for a week later to discuss vision clarity and comfort. At this time, Dr. Ramsey also checks the fit of the Scleral Contact Lenses on your eyes and any adjustments are then made.
How do you put in Scleral Contact Lenses?
Scleral Contact Lenses require a slightly different technique to insert and remove as opposed to standard soft contact lenses. The Scleral Contact Lenses need to be filled with a preservative-free, buffer-free solution prior to placing on the eye. To keep the contact filled with the solution, you will need put the contacts in while looking down.
It can take some practice to become proficient at putting in and taking out Scleral Contact Lenses, but our staff is trained to help you. We will make sure you are confident in your ability to use these contacts before you leave.
