Boston Sight

Status and phase: Withdrawn; Phase 3

Details and patient eligibility

About

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).

Full 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).
