*Abstract

BackgroundOf the 46,000 corneal transplant surgeries performed in the U.S. annually, 12% fail after the first two years. These numbers will increase in time as surgeries become available in more hospitals. Failed corneal transplants result in blindness, or require additional surgeries. In standard surgical practice, donated corneas are transplanted without attempt to properly align the cornea in the patient. That is because doctors cannot tell how the cornea was positioned in the donor so they cannot match it to the patient.TechnologyThe Polareyes Viewer allows eye doctors to determine the alignment of collagen in corneas donated for transplant, prior to surgery. Inside the Polareyes Viewer, polarized light interacts with the corneaΓÇÖs collagen to reveal structural information that cannot be seen with white light only. This information tells the doctors which way the donated cornea should be implanted to be correctly aligned in the patient. Unlike existing, expensive microscopes that accommodate polarized light, the Polareyes Viewer is inexpensive, and has a freely rotating polarizing lens to allow full view of the corneal structures. Using the information obtained by the Polareyes viewer as a part of surgical preparation may increase the strength and long-term success of the transplant. The Polareyes Viewer will benefit the over 5,700 US hospitals that perform corneal transplant surgeries as well as the international hospital community. US medical students at the 141 medical schools and 400 teaching hospitals pursuing ophthalmology can master use of the Polareyes while in training. The Polareyes Viewer is an inexpensive addition to the surgical toolkit.ApplicationThe Polareyes viewer can be used in surgical preparation to provide doctors with a directional "map" of the donated cornea that will be aligned to the patientΓÇÖs map.Advantage-Provides useful surgical information that was previously unavailable for doctors, which will ultimately benefit the patient-InexpensiveStage of DevelopmentPrototypeIP StatusUS Provisional Patent Application
