Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone-like shape. This irregular shape prevents light from focusing properly on the retina, leading to distorted or blurred vision. At Clarity Vision in Suffolk, Virginia, our eye doctors specialize in diagnosing and managing keratoconus to help patients maintain the best vision possible. The exact cause of keratoconus is not fully understood, but several factors are believed to contribute.

Genetic Predisposition

Many patients with keratoconus have a family history of the condition, suggesting that genetics play a significant role. If someone in your family has keratoconus, you may have an increased risk of developing it as well.

Eye Rubbing

Frequent or aggressive eye rubbing is one of the leading risk factors for keratoconus progression. The constant pressure and friction can weaken the corneal structure over time, causing it to thin and change shape.

Environmental and Hormonal Factors

Hormonal changes, such as those during puberty or pregnancy, may influence corneal structure. Additionally, environmental factors like chronic eye irritation, allergies, or poorly fitted contact lenses can contribute to corneal weakening.

Collagen Weakness in the Cornea

In healthy eyes, collagen fibers help the cornea maintain its round shape. In keratoconus, these fibers become weaker, allowing the cornea to gradually bulge outward into a cone shape. This change typically occurs slowly, progressing over several years.

Early Signs and Symptoms

Keratoconus often begins during the teenage years or early adulthood and may progress for 10-20 years. Common symptoms include:
 

• Blurred or distorted vision

• Increased sensitivity to light and glare

• Frequent changes in glasses or contact lens prescriptions

• Difficulty seeing at night

• Ghosting or double vision

If you notice these symptoms, it’s important to schedule a comprehensive eye exam with a skilled optometrist. Early detection allows for better management and slows the progression of the condition.

How Specialty Contact Lenses Help

While glasses can correct mild cases of keratoconus, they become less effective as the condition progresses. That’s where specialty contact lenses come in. At Clarity Vision, we offer several advanced lens options tailored to the unique shape of your cornea:
 

• Scleral Lenses: Scleral lenses are large-diameter gas-permeable lenses that rest on the white part of your eye (the sclera) instead of the cornea. They vault over the irregular corneal surface, creating a smooth optical layer that restores clear vision while providing all-day comfort.

• Hybrid Lenses: These lenses combine the crisp vision of a gas-permeable center with the comfort of a soft lens skirt. Hybrid lenses are ideal for patients who want sharper vision without sacrificing comfort.

• Rigid Gas Permeable (RGP) Lenses: RGP lenses are smaller and sit directly on the cornea. They maintain their shape, helping to correct the irregular curvature caused by keratoconus.
