Brief summary
This study will be a randomized, double-blind prospective in 3 clinical sites to compare the efficacy of two currently approved topical ophthalmic drops in the clearing central corneal staining in 90 days prior to elective cataract or LASIK surgery.
Detailed description
The study will be a randomized, double-blind prospective study in 3 sites in the US to compare efficacy of improvement in central corneal staining with fluorescein dye evaluations at slit lamp exam, secondarily improvement in OSDI questionnaire with additional questions regarding dysgeusia, blurriness, and sensation of burning, improvements in corneal topography and improvements in Schirmer's testing. 100 study subjects 18-85 male or female will be enrolled in the Nashville, Beverly Hills and St. Louis areas who are generally healthy with central corneal staining and scheduled for uncomplicated phacoemulsification or uncomplicated LASIK.
