Scleral Contacts Available

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.

How Performance Eyecare Can Help

At Performance Eyecare, our doctors guarantee that all our patients will be successful with their new contact lenses after their eye exam. We will refund all professional fees, contact lens charges, and pay the bill if another optometrist successfully fits them into contacts. It’s a guarantee you won’t find anywhere else!

Keratoconus

Keratoconus

Keratoconus is a condition in which the cornea of the eye gradually thins and begins to bulge outward and become cone-shaped. This leads to progressive vision impairment, including blurred vision and increased sensitivity to glare and light. As keratoconus progresses, it can become difficult to read, drive, or perform other simple tasks. The condition affects an estimated 1 in 2,000 people. Most people with keratoconus are diagnosed in their teenage years or 20s. The condition often progresses for up to 20 years before finally stabilizing around middle age.

Diagnosing Keratoconus:

One of the latest methods for diagnosing keratoconus involves corneal topography mapping. This test can be performed by our eye doctors. Corneal topography mapping measures the thickness of the cornea and creates a detailed map of the surface of the eye. This technology also makes it possible to categorize the severity of the disease.

Treatments for Keratoconus:

Early-stage keratoconus is typically treated with soft contacts or glasses. Frequent prescription altercations may be needed as the disease progresses. The contacts may also need to be switched from soft to rigid gas permeable to ensure adequate vision correction. Recent developments in contact lens technology have made the treatment of keratoconus a bit easier, specifically Scleral Contact Lenses. Scleral Contact Lenses cover the entire corneal service and rest on the sclera of the eye. Due to this larger form factor, they provide a more stable fit on the eye.

It is also important to note that advanced keratoconus may require surgical treatment. One surgical option involves inserting crescent-shaped rings into the cornea to correct its shape and improve vision. However, in cases where there is extensive corneal scarring and thinning, a corneal transplant (also known as a keratoplasty) may be required. This procedure replaces the damaged cornea with a cornea from a healthy donor.

At Performance Eyecare, we are committed to the early detection of different eye diseases. This is why we offer the latest in diagnostic technology including corneal topography and scleral contact lens fitting. Contact us today for more information or to schedule an appointment.
