Open Enrollment
Presbyopia Study:
A randomized and double-masked drop study for patients who suffer from Presbyopia. The purpose of the drop is to improve near vision. In this study, patients are required to make study visits and will be compensated for their time.
Crosslinking Study:
A randomized and masked study for patients diagnosed with Keratoconus. The purpose of this study is to evaluate the safety and efficacy of corneal cross-linking. In this study, patients are required to make study visits and will be compensated for their time.
Cataract Study:
A randomized and masked study for patients diagnosed with cataracts. This is a masked study for a unilateral implantation of a Toric lens. In this study, patients are required to make study visits and will be compensated for their time.
Dry Eye Study:
A randomized and double-masked study for patients diagnosed with dry eye and are currently using artificial tears. The purpose of this study is to assess the ophthalmic solution for the treatment of dry eye. In this study, patients are required to make study visits and will be compensated for their time.
Myopia, Hyperopia, & Astigmatism Study:
A LASIK clinical study to evaluate the safety and effectiveness of a new excimer laser for the correction and myopia, hyperopia, astigmatism and mixed astigmatism. In this study, patients are required to make study visits.
Current Studies
