Scleral Lenses for Keratoconus

Patients in the early stages of keratoconus are often seen wearing soft contact lenses. However, if the condition has progressed enough to cause a significant curvature of the cornea, soft lenses may no longer feel comfortable and doctors will likely recommend scleral lenses.


Scleral lenses are gas permeable contact lenses with larger diameters compared to soft contact lenses. These diameters can range in size from 14mm to 20mm. The lenses rest on the scleral (the white part of the eye) as opposed to soft lenses that rest on the cornea.


Corneas are incredibly sensitive. That is why people often find soft contact lenses extremely irritating to wear. The diameter of scleral contacts helps to stabilize the lenses, preventing them from shifting during blinks. At Global Complex Eye Care, we have found that patients beyond the early stages of keratoconus are much more comfortable wearing scleral lenses.


Scleral lenses are indeed good solutions for people who suffer from keratoconus but they are also used to treat other eye conditions as well. The eye doctors at Global Complex Eye Care will often prescribe scleral lenses for patients who cannot wear soft lenses due to suffering from chronic dry eyes. Scleral lenses have a tear reservoir located on the back of the lenses and on top of the cornea. The tear bank is designed to keep eyes moist and to relieve uncomfortable dry eyes.


The lenses may be prescribed for patients with other forms of corneal and ocular surface abnormalities. In addition, athletes that risk soft lenses being dislodged from their eye may use scleral lenses.


Experienced eye doctors, such as Dr. Irwin Azman, ensure the best fit for scleral lenses on keratoconic eyes. Scleral lenses can be designed for eyes that are in even the most advanced stages of the condition.


The specialists at Global Complex Eye Care also have in-depth consultations with patients who are new to scleral lenses. Inserting the lenses and proper maintenance may require more effort for patients who are used to soft contact lenses.


Overall we have found our patients with keratoconus are extremely pleased with scleral lenses. Wearing the lenses eliminate the burden of living with the condition and enable our patients to see clearly and be active without experiencing discomfort.
