Thirty million people in the US are thought to suffer from dry eye. Patients with this condition manifest with ocular surface disruption such as corneal fluorescein staining and reduced tear breakup time (TBUT). Successful treatment is a high priority for both patients and physicians, reducing symptoms and improving visual acuity and corneal higher order aberrations (HOAs), which have been closely linked with treatment satisfaction. A number of studies have shown the benefit of both cyclosporine and steroids in managing dry eye. However, existing formulations of these products are challenged by either limited tolerability, a high out-of-pocket cost or both. Combination therapy with these agents in an advanced, more tolerable formulation have the potential to improve both tolerability and cost. However, the available formulation of preservative free Klarity CL (cyclosporine 0.1% and loteprednol 0.2% in a chondroitin sulfate vehicle) has not been studied rigorously.~This study is designed to demonstrate that Klarity CL can benefit the ocular surface with high tolerability, making it a very desirable method of treating patients with dry eye.
