Handling Irregular Corneas: Custom Orthokeratology for Keratoconus Risk

For individuals at risk of keratoconus or those with irregular corneas, finding a comfortable and effective vision correction option can be challenging. Standard contact lenses or glasses may not provide the clarity or stability needed, especially when the corneal surface is uneven. At San Marino Optometry, we specialize in custom Orthokeratology (Ortho-K) lenses designed to meet these unique needs - helping protect vision and support long-term eye health.

Understanding Keratoconus Risk and Irregular Corneas

Keratoconus is a progressive condition where the normally round cornea thins and bulges into a cone-like shape. This irregularity causes distorted vision, glare, halos, and increased light sensitivity. In the early stages or for those at risk (due to genetics, chronic eye rubbing, or underlying conditions) managing the cornea’s shape and protecting its integrity is essential to slowing progression.

Irregular corneas can result from:

• Early keratoconus

• Post-LASIK or PRK complications

• Corneal injuries or scarring

• Other corneal diseases or structural changes

Because these conditions make the eye’s surface uneven, traditional vision correction often doesn’t fit well or deliver consistent clarity.

How Custom Orthokeratology Helps

Orthokeratology uses specially designed, gas-permeable contact lenses worn overnight to gently reshape the cornea. In the morning, the lenses are removed, allowing you to enjoy clearer vision throughout the day without the need for glasses or daytime contact lenses.

For patients with keratoconus or those with existing irregular corneas, custom Ortho-K lenses can be tailored to address their specific needs. These lenses are designed to fit the unique topography of each cornea, reduce visual distortions by creating a more regular optical surface, and support corneal stability to help prevent further shape irregularity. They also provide a non-invasive, reversible alternative to surgical options.

Using advanced corneal mapping technology, each lens is crafted with precision to ensure an optimal fit for the individual shape of every eye, delivering both comfort and improved visual clarity.

Benefits of Ortho-K for Keratoconus

• Improved Vision Quality - More consistent focus compared to standard lenses on irregular surfaces.

• Comfortable Wear - Designed to fit precisely, reducing the irritation that can come with poorly fitting contacts.

• Non-Surgical Approach - Avoids risks associated with corneal surgery or transplants.

• Lifestyle Freedom - Clear daytime vision without the need for glasses or contacts during waking hours.

Early Detection and Ongoing Care Are Key

Managing keratoconus isn’t just about the right lens - it’s also about regular eye exams and monitoring. Early intervention gives you the best chance of maintaining clear, stable vision. Our optometrists use advanced diagnostic tools to detect subtle changes in corneal shape, ensuring your treatment stays effective.
