How Scleral Lenses Restore Clear Vision for Keratoconus Patients in San Antonio

Keratoconus can make clear, comfortable vision difficult because the cornea gradually becomes thinner and develops an irregular, cone-like shape. This irregularity can cause blurred or distorted vision that may not be fully corrected with standard glasses or traditional soft contact lenses.

At Stone Oak Vision Source, we provide keratoconus care and scleral lenses for patients in San Antonio who need a more customized approach to vision correction.
 

Why Keratoconus Can Affect Vision

A healthy cornea has a smooth, rounded surface that helps focus light properly onto the retina. With keratoconus, changes in the corneal shape can cause light to scatter instead of focusing evenly. Patients may experience increasing astigmatism, blurry vision, glare, halos, light sensitivity, or frequent prescription changes.

Because every keratoconus patient has a different corneal shape, effective vision correction often requires a lens designed around the individual's eye.
 

How Scleral Lenses Work

Scleral lenses are larger-diameter gas permeable contact lenses that rest on the white portion of the eye, called the sclera. Instead of sitting directly on the irregular cornea, the lens vaults over it.

The space between the scleral lens and the cornea is filled with sterile preservative-free saline before insertion. This fluid reservoir helps create a smooth optical surface, allowing light to focus more consistently despite the irregular shape of the cornea.

For many keratoconus patients in San Antonio, this design can provide clearer and more stable vision than conventional correction.
 

Benefits of Scleral Lenses for Keratoconus

Depending on the condition of the eyes and the severity of keratoconus, scleral lenses may offer several advantages:

• Sharper and more consistent vision

• Improved correction of irregular astigmatism

• Greater stability on the eye

• Reduced dependence on glasses for clear vision

• A customized fit based on the shape of the eye

Scleral lenses can also be especially useful when standard soft contact lenses do not provide adequate correction.
 

A Customized Scleral Lens Fitting Matters

Scleral lenses are not one-size-fits-all. A careful evaluation is needed to examine the cornea, assess the extent of keratoconus, and determine whether scleral lenses are appropriate.

During the fitting process, we evaluate how the lens vaults over the cornea, where it rests on the sclera, and how well it provides clear vision. Adjustments may be needed to achieve the appropriate fit and visual performance.

We also provide instructions for lens insertion, removal, cleaning, disinfection, and filling. Scleral lenses should be filled only with sterile preservative-free saline as directed. Saline used for filling does not disinfect the lenses, so patients should follow the recommended cleaning and disinfection routine separately.
 

Keratoconus Care in San Antonio

Keratoconus can change over time, which makes regular eye examinations and ongoing monitoring important. If your vision remains blurry despite updated glasses or standard contacts, an evaluation can help determine whether an irregular cornea may be contributing to the problem.

At Stone Oak Vision Source, we offer specialized care for keratoconus, including scleral lens treatment, as part of our eye care services for the San Antonio community.
