Novel Use of Restasis and PROSE Devices

Study Overview
=================
Brief Summary
-----------------
The goal of this prospective observational pilot study is to evaluate the tolerability and safety of RESTASIS (cyclosporine ophthalmic solution 0.05%) when added to the PROSE (Prosthetic Replacement of the Ocular Surface Ecosystem) lens reservoir in patients with ocular surface disease (OSD).

Detailed Description
-----------------
For this study, all subjects will receive Restasis (Cyclosporine ophthalmic emulsion 0.05%). One drop of the dispensed study drop will be instilled in the PROSE lens reservoir twice a day and the remainder of the reservoir will be filled with normal saline (0.9% sodium chloride solution). In order to standardize solutions used in the PROSE reservoir, all patients recruited will be either currently using or will be switched to buffered preservative-free normal saline (Purilens, Lifestyle Inc., pH 7.4 ) to better match the reported pH of RESTASIS (pH 6.5-8.05).
