Femtosecond Laser for Cataract Surgery

A Prospective, Randomized Study of Cataract Surgery With the Assistance of the OptiMedica Femtosecond Laser System Compared to Standard Surgical Procedure of Continuous Curvilinear Capsulorhexis and Ultrasonic Phacoemulsification

The objective of this study is to evaluate the safety and efficacy the OptiMedica Femtosecond Laser System, also known as the Catalys™ Precision Laser System, to perform two surgical maneuvers used in the treatment of subjects with cataracts. Efficacy will be evaluated by comparisons to the standard surgical procedure of continuous curvilinear capsulorhexis (CCC) and ultrasonic phacoemulsification.
