Abstract

DESCRIPTION (provided by applicant): The objective of this grant proposal is to perform a clinical study which will allow the first foldable and injectable artificial cornea, the KeraKlear, to be used in the United States market for treatment of corneal blindness. This device may be implanted through an incision size that is approximately 1/10th the size of the incision that is required for the most popular artificial cornea available in the U.S. The smaller incision size is expected to allow a much quicker surgery for patients and a more accelerated recovery as compared to the currently available artificial corneas. In addition, the KeraKlear artificial cornea may be implanted in many patients with cornea blindness without penetration into the anterior chamber. This avoids two of the most serious complications of artificial cornea implantation including internal infection of the eye (endophthalmitis) and severe bleeding (expulsive hemorrhage). The use of the KeraKlear artificial cornea also avoids the common complications of corneal transplantation including high astigmatism, corneal graft failure and corneal graft rejection. Finally, the KeraKlear would enable the treatment of cornea blindness in a much larger number of patients. Currently, corneal transplantation is limited to about 100,000 per year worldwide because of the lack of suitable donor corneas. This represents only 1% of the 10 million people worldwide who have cornea blindness in both eyes. By making the KeraKlear artificial cornea available a significantly larger percentage of the cornea blind patients around the world could be treated.
