Patients with keratoconus (cone-shaped corneas) or post-LASIK ectasia can take part in a new clinical trial at Henry Ford Hospital. The rare condition pushes the cornea into a cone shape. The trial investigates corneal collagen cross-linking, a treatment designed to help stop the progression of keratoconus by strengthening corneal tissue.In patients with keratoconus, the cornea has an irregular surface, resulting in a distorted image improved by wearing rigid contact lenses. There has not been another option for patients with keratoconus who cannot tolerate these lenses until this experimental cross-linking procedure was developed.The clinical trial involves a procedure in which an ophthalmologist temporarily removes the numbed top layer of the cornea. Drops are placed in the eyes and then the cornea is exposed to ultraviolet light for a period of time.Three study groups will be assigned different lengths of time for UVA exposure and participants are followed for 12 months. Treatments are free and screening visits and follow-up testing are covered by insurance.For more information about enrollment, call (313) 916-2481.
