Scleral Lens

What are scleral lens?


If you've been told in the past that you cannot wear contact lenses because of an irregular cornea or other problems, you may want to get a second opinion and ask your eye doctor about scleral contact lenses.


Scleral contacts are large-diameter gas permeable contact lenses specially designed to vault over the entire corneal surface and rest on the "white" of the eye (sclera). In doing so, scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by keratoconus and other corneal irregularities.


Also, the space between the cornea and the back surface of a scleral lens acts as a fluid reservoir to provide comfort for people with severe dry eyes who otherwise could not tolerate contact lens wear.


Are scleral lens covered by insurance?


Many patients are not aware that the fitting evaluation and scleral contact lenses are often covered by medical and vision insurance plans if the lens devices are deemed "medically necessary".

Our team goes above and beyond to assist our patients with this process. As a courtesy, our Brooklyn office also offers Care Credit financing to those who qualify. All patients will receive a copy of our specialty contact lens prescription and management contract. Once full payment is received, custom diagnostic lenses will be fit and ordered. Professional service fees are non-refundable. Scleral lens material fees are refundable.


What is included in the scleral lens evalutation?


During the consultation, all previous medical and ocular records are reviewed. Corneal topography , anterior segment optical coherence tomography, and pachymetry are performed. Dr. Diana Nguyen will then diagnostically fit trial scleral lens devices on the eye(s) to determine best corrected and potential for visual improvement and relief of ocular symptoms.

If during the consultation it is determined that scleral lens devices are indicated, custom prosthetic lens devices will be ordered. The patient will then return for post-fitting visits to learn insertion, removal, and care of the scleral lenses.

Our staff are experts with training. The diagnostic lenses are evaluated by one of our doctors and dispensed. The patient is asked to return at one week wearing the lenses for a minimum of six hours and the lens device(s) are then evaluated again by Dr. Diana Nguyen with the precise aid of anterior segment optical coherence tomography.





Who is a good candidate for scleral lenses?


Here’s some examples of how scleral contact lenses can benefit you:


  • Irregular corneas. Vision problems caused by an irregularly shaped cornea — whether due to an eye condition such as keratoconus, high astigmatism, trauma to the eye, or resulting from eye surgery (such as Radial Keratotomy)— typically cannot be fully corrected with glasses or soft contact lenses. Scleral lenses typically will provide sharper vision for these eyes.

  • Hard-to-fit eyes. If you cannot comfortably wear conventional contact lenses, or the shape of your eye causes the lenses to dislodge too easily from your eyes (during sports for example), scleral lenses can provide a more comfortable and secure fit to help you see better. This will enhance your sports performance to catch, hit or throw more accurately!

  • Dry eyes. If your eyes are too dry for conventional contact lenses, scleral lenses can help. The space between the cornea and the inside surface of the scleral lens allows for fluid intake and creates a moist reservoir that can help patients with dry eyes be able to wear contact lenses.
