Arm Intervention/treatment
Experimental: FLACS
FLACS in 1 eye, with manual conventional surgery in the fellow eye, as randomized
Procedure: FLACS
Femtosecond laser assisted cataract surgery consisting of LenSx® and Centurion® combination

Device: CENTURION® Vision System
Phacoemulsification aspiration platform for use during cataract surgery

Device: LenSx®
Femtosecond laser system used for continuous curvilinear capsulorhexis (CCC) and lens fragmentation during cataract surgery

Active Comparator: Conventional
Manual conventional surgery in 1 eye, with FLACS in the fellow eye, as randomized
Procedure: Manual conventional surgery
Removal of cataractous lens by phacoemulsification

Device: CENTURION® Vision System
Phacoemulsification aspiration platform for use during cataract surgery

Primary Outcome Measures :
  1. Cumulative Dissipated Energy (CDE) [ Time Frame: Surgery (Day 0) ]
    CDE (the energy dissipated at the incision point during the removal of cataractous lens) will be measured.

Secondary Outcome Measures :
  1. Percent change of corneal endothelial cell density (ECD) [ Time Frame: Day 150-210 post-surgery ]
    Specular microscopy will be performed and endothelial cell density will be recorded.

  2. Average torsional amplitude [ Time Frame: Surgery (Day 0) ]
    Torsional amplitude will be recorded by Centurion® and measured as a percentage.
