Some of us have been told we can’t wear contact lenses because of an irregular cornea or other problems. If this is true for you or someone you know, you may want to get a second opinion and ask the eye doctors at Performance Eyecare about scleral contact lenses.
As described by Jason Jedlicka, OD of AllAboutVision.com, “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. 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.”
What is keratoconus?
Keratoconus a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This shape deflects lights as it enters the eye on its way to the light-sensitive retina. This causes distorted vision.
Many optometrists and ophthalmologists recommend scleral contact lenses for a variety of hard-to-fit eyes, including eyes with keratoconus.
A standard GP lens may be used in early cases of keratoconus, but a large-diameter scleral contact lens may be needed if the lens doesn’t center properly on the eye or moves excessively with blinks and causes discomfort.
Scleral lenses are often more comfortable for a person with keratoconus because they are designed to vault the corneal surface and rest on the less sensitive surface of the sclera. These lenses are also designed to fit with little or no movement during blinks, making them more stable on the eye compared to traditional corneal gas permeable lenses.
