Living with keratoconus often means dealing with vision that feels inconsistent, distorted, or difficult to correct with standard eyewear. As the cornea becomes thinner and develops a more cone-like shape, light no longer focuses evenly on the retina. This often leads to blurry vision, astigmatism, glare, light sensitivity, and frequent prescription changes.

For patients throughout the San Gabriel Valley who are frustrated with glasses or traditional soft contacts, scleral lenses offer a more specialized approach to vision correction.

Why Glasses Have Limitations with Keratoconus

Glasses correct refractive errors using a prescription positioned in front of the eyes. In earlier or milder stages of keratoconus, this may provide satisfactory vision. As the cornea becomes increasingly irregular, however, updating the eyeglass prescription does not change the uneven corneal surface responsible for visual distortion.

This is why some people with keratoconus notice that their prescription keeps changing while their vision still does not feel as sharp or stable as they would like.

Why Traditional Soft Contacts May Fall Short

Soft contact lenses conform closely to the shape of the cornea. While this works well for many standard prescriptions, following an irregular keratoconic cornea means the lens may not fully compensate for its uneven shape.

Patients with more significant keratoconus may experience blurred or distorted vision even when their soft contact lens prescription is technically correct. Specialty rigid and scleral lenses are commonly considered when standard correction no longer provides adequate visual clarity.

How Scleral Lenses Create Sharper Vision

Scleral lenses work differently. These larger, rigid gas-permeable lenses vault over the cornea and rest on the white portion of the eye, known as the sclera. A reservoir of preservative-free saline fills the space between the lens and cornea, helping create a smooth optical surface over the irregular corneal shape.

For people with keratoconus, this design offers several important advantages:

• Sharper and more stable vision over an irregular cornea
• Less dependence on constantly changing eyeglass prescriptions
• A lens that does not sit directly on the sensitive corneal surface
• A fluid reservoir that keeps the corneal surface hydrated
• A customized fit based on the unique shape of each eye

The goal is not simply to increase prescription strength. Scleral lenses address the optical irregularity created by keratoconus, which is why they often provide clearer vision when traditional options no longer meet a patient's needs.

Custom Scleral Lens Fitting Matters

Scleral lenses are specialty medical devices that require careful evaluation and fitting. At Gratitude Vision Optometry, we assess your eyes and determine the lens design needed to properly vault the cornea, align with the sclera, and provide stable vision and comfort. Our personalized fitting process is designed around the individual characteristics of your eyes rather than relying on a standard contact lens fit.
