CENTURIONINFINITI® Vision System (IVS)First surgical eye randomized to CENTURION® Vision System, with second surgical eye (fellow eye) assigned to INFINITI® Vision System. Second eye surgery conducted within 14 days of the first eye surgery. Duration of surgery less than 30 minutes each eye.
INFINITICENTURION® Vision System (CVS)First surgical eye randomized to INFINITI® Vision System, with second surgical eye (fellow eye) assigned to CENTURION® Vision System. Second eye surgery conducted within 14 days of the first eye surgery. Duration of surgery less than 30 minutes each eye.

Primary Outcome Measures
NameTimeMethod
Cumulative Dissipated EnergyDay 0 (operative day), each eye

Cumulative Dissipated Energy (CDE) is an estimation of the energy at the incision site experienced during the removal of cataractous lens and is measured in %-secs. The incision is defined as 5.6mm back from the cutting edge of the tip. A lower CDE indicates that less energy was present at the incision site.

Aspiration (ASP) Fluid UsedDay 0 (operative day), each eye

Aspiration fluid used is the amount of aspiration fluid used during the removal of the cataractous lens. A lower value indicates that less fluid was removed from the eye.

Secondary Outcome Measures
NameTimeMethod
Aspiration TimeDay 0 (operative day), each eye

Aspiration Time indicated the amount of time the system was aspirating during the removal of the cataractous lens. A lower value indicates that the surgeon spent less time aspirating fluid and material from the eye during surgery.
