Explore Cutting-Edge Corneal Contouring for Keratoconus

Corneal Tissue Addition for Keratoplasty (CTAK) is an innovative, less-invasive treatment for keratoconus that combines greater surgical precision with enhanced patient outcomes and faster recovery times. Based on Pentacam® tomography data, CorneaGen designs and laser-cuts custom CTAK inlays for each patient. These fully customizable tissue inlays are designed to improve visual acuity, increase corneal thickness, and enhance corneal stability through natural, stable topographic flattening.

CorneaGen states that 100% of patients experienced improved uncorrected distance visual acuity post-procedure in a clinical trial, underscoring its effectiveness and reliability.

Hear About CTAK’s Impact from the Experts

“CTAK has been a game-changer for our keratoconus patients, significantly improving both their uncorrected vision and vision in glasses. These results are possible because of the customized inlays which are cut to specifications guided by Pentacam® tomography maps which are then uploaded to CTAK planning software.”

–   Steven Greenstein, M.D.

“Many of my keratoconus patients express that while contact lenses provide adequate vision, they are non-functional without them. A common fear is being unable to handle emergencies due to their dependence on contact lenses for basic vision. CTAK can change this. It benefits a wide range of patients, from mild to severe. It improves uncorrected and spectacle-corrected vision, regularizes the cornea, and can expand contact lens and surgical options. It enhances the overall quality of life.”
