Official Title: A Clinical Trial to Evaluate the Safety and Effectiveness of the Collagen-phosphorylcholine Corneal Substitutes in Patients Requiring Lamellar Keratoplasty
Brief Summary: In this study the safety and effectiveness of biosynthetic cornea, comprising interpenetrating networks of recombinant human collagen and phosphorylcholine, will be tested in patients with severe corneal pathology (corneal ulcers or corneal opacification from corneal injury, burn or infection) - diseases, where human donor cornea transplantation (the only widely accepted treatment) carries a high risk of rejection.
