How Scleral Lenses Can Help With Keratoconus and Irregular Corneas

If you’ve been diagnosed with keratoconus or another condition that causes an irregular cornea, you may already know how frustrating distorted, blurry vision can be. Glasses often don’t provide enough clarity, and traditional contact lenses may feel uncomfortable or unstable. At Della Porta EyeCare, patients with complex corneal conditions find renewed clarity and comfort through advanced scleral lens technology and precise, customized fittings with Dr. Della Porta.

Understanding Keratoconus and Irregular Corneas

The cornea is the clear, dome-shaped surface at the front of the eye. In a healthy eye, it maintains a smooth, round shape that allows light to focus properly on the retina.

With keratoconus, the cornea gradually thins and bulges outward into a cone-like shape. Other conditions, including corneal scarring, post-surgical changes (such as after LASIK or corneal transplants), and severe dry eye, can also create irregular corneal surfaces.

When the cornea becomes uneven, light scatters instead of focusing correctly. This can cause:

• Blurred or distorted vision
• Increased glare and halos
• Frequent prescription changes
• Sensitivity to light
• Difficulty seeing clearly at night

In these cases, traditional glasses or soft contact lenses often cannot correct vision effectively.

What Are Scleral Lenses?

Scleral lenses are specialized gas-permeable contact lenses that are larger in diameter than standard contacts. Instead of resting directly on the cornea, they vault over it entirely and rest on the sclera (the white part of the eye). This unique design creates a smooth optical surface over the irregular cornea while maintaining a fluid reservoir between the lens and the eye. The result is clearer, more stable vision and enhanced comfort.

How Scleral Lenses Improve Vision in Keratoconus

Scleral lenses work differently from glasses or soft contacts. By vaulting over the irregular cornea, scleral lenses provide a perfectly smooth refractive surface. Light can then focus properly onto the retina, significantly improving clarity and sharpness.

Because scleral lenses rest on the sclera rather than the sensitive cornea, they are more stable and less likely to shift or dislodge. This stability is especially important for patients with advanced keratoconus.

The fluid reservoir beneath the lens also keeps the eye continuously hydrated. This can provide relief for patients who also experience dryness or discomfort from corneal irregularities.

The Importance of Precise Fitting

Scleral lenses are highly customized medical devices. Achieving optimal vision and comfort requires detailed measurements and careful adjustments. Dr. Della Porta uses advanced diagnostic technology to map the unique shape of your cornea. This allows for a truly personalized fit that accounts for:

• The degree and pattern of corneal irregularity
• Corneal elevation differences
• Eye surface health
• Tear film stability

A precise fit is essential. If a scleral lens does not vault correctly or distributes pressure unevenly, it can reduce comfort and effectiveness. Dr. Della Porta’s expertise ensures that each lens is designed to provide maximum clarity, stability, and long-term eye health.
