Keratoconus Patient Fit Into EyePrint Prosthetic

For patients with advanced keratoconus, standard glasses and soft contact lenses often fall short of providing usable vision. When the cornea becomes highly irregular, specialty lens options like the EyePrint Prosthetic can deliver dramatic visual improvement. This Las Vegas patient’s experience shows how custom-molded prosthetic lenses can restore functional vision even in severe keratoconus cases.

What Is the EyePrint Prosthetic?

The EyePrint Prosthetic is a custom scleral lens created from a physical impression of the patient’s eye, similar to how a dental mold captures the exact shape of your teeth. This impression captures every contour of the cornea and sclera, allowing the lab to fabricate a lens that matches the eye’s unique surface with exceptional precision.

This technology is particularly valuable for patients whose corneas are too irregular for standard scleral lens designs. Because the lens is built from a direct mold rather than estimated from measurements alone, it can achieve a fit and comfort level that off-the-shelf designs may not provide.

How Did Keratoconus Affect This Patient’s Vision?

A 23-year-old male with keratoconus was referred for a specialty contact lens consultation. With his glasses, he could only achieve 20/400 in the right eye and 20/40 in the left eye, with significant ghosting and double vision in the left eye.

Corneal topography confirmed irregular astigmatism in both eyes, with the right eye more severely affected. The right eye showed stromal striae and corneal thinning, both hallmarks of progressive keratoconus. The left eye also showed thinning, though the remaining ocular structures appeared healthy.

For context, 20/400 vision means the patient could only see at 20 feet what a person with normal vision sees at 400 feet. At this level, most daily activities including driving, reading, and recognizing faces become extremely difficult.

Why Was the EyePrint Prosthetic Selected?

After discussing the available specialty lens options, including standard scleral lenses, hybrid lenses, and the EyePrint Prosthetic, the patient chose the EyePrint for both eyes. The decision was based on the severity of his corneal irregularity, particularly in the right eye, where the degree of distortion made a custom-molded approach the most promising path to clear vision.

An impression of each eye was taken in the office, capturing the precise three-dimensional shape of both the cornea and surrounding sclera. A diagnostic scleral lens fitting was also performed to evaluate the vision potential before the custom devices were manufactured.

What Results Did the EyePrint Achieve?

The visual improvement was remarkable. The right eye improved from 20/400 to 20/25, and the left eye improved from 20/40 with ghosting and double vision to 20/15 with no ghosting or double vision. This level of improvement is life-changing for a young patient, restoring the ability to drive, work, and participate in daily activities with confidence.

These results demonstrate the power of custom prosthetic lens technology for patients with severe corneal irregularity. When standard corrections are not enough, the EyePrint Prosthetic can unlock visual potential that other options cannot reach.

Key Takeaways for Keratoconus Patients

• If glasses or standard contact lenses are not giving you clear vision, specialty lenses such as scleral lenses or the EyePrint Prosthetic may be able to help.
• The EyePrint uses a custom mold of your eye to create a lens that precisely matches your unique corneal shape.
• Even patients with very advanced keratoconus and severely reduced vision can often achieve significant visual improvement with the right lens.
• Keratoconus is a progressive condition, so regular follow-up appointments are important to monitor changes and update your lens fit as needed.
• If you notice a sudden worsening of vision, increased eye pain, or new sensitivity to light, contact your eye doctor promptly, as these may be signs of progression or a complication that needs attention.
