Summary
The purpose of this study is to evaluate the safety and efficacy of the OptiMedica Femtosecond Laser System to perform surgical maneuvers used in the treatment of subjects with cataracts. The safety and efficacy will be compared to the standard surgical procedure of continuous curvilinear capsulorhexis (CCC) and ultrasonic phacoemulsification.
