Description

The use of a Prosthetic Replacement of the Ocular Surface Environment (PROSE) device is a revolutionary treatment for military patients that have lost their eyelids due to 3rd degree facial burns or for civilians who suffer from a host of corneal diseases. However, custom manual fitting is often a protracted painful, inexact process that require multiple fitting sessions. Training for new practioners is a long process. Automated methods to measure the complete corneal and scleral topology would provide a valuable tool for both clinicians and PROSE device manufacturers and would help streamline the fitting process. In Phase I PSI will demonstrate the feasibility of using high-resolution swept-source Optical Coherence Tomography (OCT), a unique scanning system with automatic stitching and segmentation software to measure the complete 3D surface profile of the anterior segment of the eye. Rapid OCT metrology will ultimately provide enhanced patient comfort during the PROSE process with improved post-surgical prostheses protecting vision in military and civilian patients. A fast (<1s), high resolution (<10µm), wide field (>20 mm scans) imaging device will precisely fit contacts for each patients"eyes, reduce the cost and number of fitting trials, and the time spent by doctors, technicians and patients.
