Arm Intervention/treatment
Experimental: FS Laser Surgery
For femtosecond laser-assisted cataract surgery (FS Laser Surgery), subjects will receive capsulotomy, lens segmentation and, at investigator discretion, lens softening using the OptiMedica Catalys™ Precision Laser System (Catalys System)
Procedure: FS Laser Surgery
The Catalys System is an ophthalmic surgical laser system intended for use in cataract surgery. The intervention consists of the both surgery and the use of the device.

Primary Outcome Measures :
  1. Capsulotomy Size [ Time Frame: Day of Surgery ]
    Capsulotomy size will be measured during surgery.


Secondary Outcome Measures :
  1. Cumulated Dissipated Energy (CDE) [ Time Frame: Day of surgery ]
    CDE (the amount of ultrasound energy delivered during phacoemulsification of the crystalline lens) used will be measured during surgery.
