Arm Intervention/treatment
Experimental: UltraSert Preloaded Delivery System
Preloaded IOL delivered via a 2.2 mm clear corneal incision during cataract surgery
 Device: UltraSert Preloaded Delivery System
Includes AcrySof IQ monofocal posterior chamber IOL Model AU00T0, intended for long term use over the lifetime of the subject
Active Comparator: iTec Preloaded Delivery System
Preloaded IOL delivered via a 2.2 mm clear corneal incision during cataract surgery
 Device: iTec Preloaded Delivery System
Includes TECNIS 1-piece monofocal IOL, intended for long term use over the lifetime of the subject
Active Comparator: iSert Preloaded Delivery System
Preloaded IOL delivered via a 2.2 mm clear corneal incision during cataract surgery
 Device: iSert Preloaded Delivery System
Includes Model 251 or Model 250 posterior chamber IOL, as selected by the Investigator, intended for long term use over the lifetime of the subject
Active Comparator: Monarch III D Manual IOL Delivery System
Manually loaded IOL delivered via a 2.4 mm clear corneal incision during cataract surgery
 Device: Monarch III D Manual IOL Delivery System
Includes AcrySof IQ monofocal IOL posterior chamber IOL Model SN60WF, intended for long term use over the lifetime of the subject


Outcome Measures

Primary Outcome Measures :
  1. Mean Corneal Incision Size After IOL Implantation (UltraSert, iTec, and iSert) [ Time Frame: Day 0, operative day ]
    Post-IOL implantation corneal incision size was measured directly after IOL implantation and reported in millimeters (mm). Minimizing enlargement of incision size during cataract surgery results in less postoperative inflammation, less surgically-induced astigmatism, and more rapid visual and wound rehabilitation. This endpoint was prespecified for the UltraSert, iTec, and iSert preloaded delivery systems. Only one eye (study eye) contributed to the analysis.


Secondary Outcome Measures :
  1. Mean Corneal Incision Size After IOL Implantation (UltraSert and Monarch III D) [ Time Frame: Day 0, operative day ]
    Post-IOL implantation corneal incision size was measured directly after IOL implantation and reported in millimeters (mm). Minimizing enlargement of incision size during cataract surgery results in less postoperative inflammation, less surgically-induced astigmatism, and more rapid visual and wound rehabilitation. This endpoint was prespecified for the UltraSert preloaded delivery system and the Monarch III D delivery system. Only one eye (study eye) contributed to the analysis.
