What Is Keratoconus? Symptoms, Causes, and Treatment Options Explained

If you’ve noticed increasing blur, distortion, or frequent changes in your eyeglass prescription, you may be wondering what’s causing it. One possible reason is keratoconus - a progressive eye condition that affects the shape and clarity of your cornea. At Lumen Eye Center, we help patients understand keratoconus and offer advanced solutions to restore clearer, more comfortable vision.

What Is Keratoconus?

Keratoconus is a condition in which the cornea gradually thins and bulges outward into a cone-like shape. A healthy cornea is smooth and evenly curved, helping focus light clearly onto the retina. When the cornea becomes irregularly shaped, light scatters instead of focusing properly, leading to distorted and blurred vision.

Keratoconus typically begins in the teenage years or early adulthood and may progress over time. Early detection and proper management are key to preserving vision and comfort.

What Are the Symptoms of Keratoconus?

In its early stages, keratoconus can look similar to simple nearsightedness or astigmatism. As it progresses, symptoms often become more noticeable and harder to correct with glasses.

Common symptoms include:

• Blurred or distorted vision
• Increased sensitivity to light and glare
• Frequent changes in eyeglass prescription
• Difficulty seeing clearly at night
• Halos or ghosting around lights
• Eye strain or headaches

If you find that your vision seems to change rapidly or glasses no longer provide clear vision, a comprehensive eye exam is important.

What Causes Keratoconus?

The exact cause of keratoconus isn’t fully understood, but several factors are believed to contribute:

• Genetics (family history of keratoconus)
• Chronic eye rubbing
• Underlying connective tissue conditions
• Long-term eye irritation or inflammation

Many cases develop without a clear cause. Because keratoconus often progresses gradually, routine eye exams play a critical role in catching early signs before vision becomes significantly affected.

Treatment Options for Keratoconus

Keratoconus is diagnosed through a comprehensive eye exam that includes detailed corneal measurements. At Lumen Eye Center, we use advanced diagnostic technology to evaluate corneal shape, thickness, and overall eye health to determine the most appropriate treatment plan.

Scleral lenses are often one of the most effective solutions for keratoconus. Unlike traditional contacts that rest directly on the cornea, scleral lenses vault over the cornea and rest on the white part of the eye (the sclera). This design:

• Creates a smooth optical surface for clearer vision
• Reduces irritation by avoiding contact with the sensitive cornea
• Holds a reservoir of fluid that can improve comfort

Many patients who struggle with other lenses find scleral lenses to be life-changing in terms of comfort and visual clarity.
