Am I a Candidate for Scleral Lenses?

Scleral lenses are large-diameter, customized, hard contact lenses. These vault over the cornea and sit on the sclera, the white region of the eye. Since these lenses do not rest on the cornea, a tear and saline chamber forms between the lens and the cornea. This space permits sufficient oxygen to reach the eyes while also keeping the eyes moist.


More patients prefer scleral lenses to regular contact lenses. The reason for this is their comfort, less irritability, and better fit. In addition, scleral lenses have improved coverage, more stability, and are easier to handle. Also, the design of the lenses eliminates the need to mold the lens to the curvature of the cornea. This benefits any patient with corneal abnormalities.


Who Is a Candidate for Scleral Lenses?


Scleral lenses were formerly exclusively advised for individuals with an irregularly shaped cornea. However, their usage has grown, and currently, any patient with vision issues that is unable to attain clarity with glasses or traditional contact lenses could be a suitable candidate for scleral lenses. Scleral lenses are a good choice for people suffering from eye disorders such as:


Dry Eye


These patients cannot generate enough natural tear film. Their tear film drains too fast or is of low quality so that it does not offer sufficient lubrication. Scleral lenses leave a gap between the lens and the eye, which functions as a tear film reservoir. This decreases symptoms of dry eye in individuals who are unable to use regular contacts due to their disease.


Irregularly Shaped Cornea


Some patients have a steeper cornea that is more conical in shape. This makes regular contacts unpleasant, less stable, and difficult to properly fit. These patients find scleral lenses more useful because they only vault over the cornea and are less likely to be impacted by abnormalities.




This is an eye condition that causes the cornea to bulge and thin. Patients with this condition find it uncomfortable wearing regular glasses and contacts due to their unusually shaped cornea.


Hard to Fit Eyes


Some individuals have trouble finding regular contact lenses that properly match their natural eye shape. Scleral lenses are larger compared to regular contact lenses. Scleral lenses will thus be an excellent and comfortable fit for these patients.


Ocular Surface Diseases


Ocular surface disease refers to damage to the eye's surface layers, specifically the cornea and conjunctiva. The two most frequent causes of ocular surface illness are dry eye syndrome and blepharitis. These diseases make it challenging to wear regular contact lenses. Scleral lenses function as a protective shield for the damaged ocular surface. They allow an individual's eyesight to improve.


Corneal Degeneration


Corneal degenerations are changes or progressive deteriorations in the cornea's tissue. These can impair the cornea's function, decreasing its ability to help the eye focus. Corneal degeneration makes it difficult for patients to see clearly even with the help of regular eye contact.


Injury to the Eye


Accidents happen, and the person may suffer a chemical burn or be struck in the eye. This may cause swelling or even damage to the cornea. Scleral lenses would be ideal for such patients.
