3

Scleral Contact Lens Fitting

Large-diameter gas permeable lenses that vault over the cornea and rest on the sclera, providing superior vision correction and comfort in moderate keratoconus.

procedure

Additional treatment options

Topography-Guided PRK

Laser photorefractive keratectomy customized to the corneal shape to regularize the surface and improve spectacle-corrected vision.

surgical

Specialized Nutritional Support

Supplementation with omega-3 fatty acids and antioxidants may support corneal health, though evidence for disease modification is limited.

complementary

Hybrid Contact Lens System

Combination lenses with rigid center and soft skirt for improved comfort while providing the optical benefits of rigid lenses in moderate keratoconus.
