5. Study Description

Brief Summary
EYEdeal Scanning Technology enables rapid measurement of corneal and scleral topography. By accurately measuring the ocular surface with this imaging technology, the current iterative fitting method required to fit PROSE (prosthetic replacement of the ocular surface ecosystem) devices could be replaced and/or strengthened with a more rapid, automated fitting sequence. This could considerably reduce the time needed per visit, the number of visits, and the number of devices needed to be manufactured to reach the endpoint. Additionally, the scanning technology may afford the opportunity to successfully fit some pathology that were previously treatment failures. The automated technology may as well reduce the intensive clinician training time needed to fit PROSE devices, therefore increasing the availability and access to patients. The goal of this research is to evaluate the reliability and efficacy of this automated technology for fitting PROSE devices. Data from real-time measurement of the human eye ocular surface topography will be used to fabricate a prosthetic lens. The fit of the PROSE device will be evaluated, as well as the subjective comfort of the fit.
