Intra-Operative Metrics With CENTURION® and INFINITI® Vision Systems

Not Applicable

Completed

Brief Summary: The purpose of this study is to evaluate intra-operative phacoemulsification machine metrics after phacoemulsification with the CENTURION® vision system configuration compared with the INFINITI® vision system configuration.

Recruitment & Eligibility

Inclusion Criteria

Eligible to undergo cataract extraction via phacoemulsification with primary ACRYSOF Intraocular Lens (IOL) implantation;
Free of severe disease(s)/condition(s) listed in the "Warnings" and "Precautions" section of implanted ACRYSOF IOL;
Willing to undergo second eye surgery within 14 days of first eye surgery;
Willing and able to understand/sign a written Informed Consent Document;
Willing and able to return for scheduled follow-up examinations;
Other protocol-defined inclusion criteria may apply.

Exclusion Criteria

Planned multiple procedures at the time of surgery or during the course of the study (eg, LASIK, LRI, etc.);
Previous intraocular or corneal surgery of any kind;
Poorly dilating pupil;
Severe retinal disorders (eg, macular degeneration, proliferative diabetic retinopathy);
Corneal disease (eg, herpes simplex, herpes zoster, etc) or retinal detachment;
Severe conditions that per Investigator's clinical judgment would increase the operative risk or confound the result of this investigation;
Female patients who are pregnant, lactating, or planning to be pregnant during the course of the study;
Currently participating in another drug or device clinical trial, or participated in another drug or device clinical trial within 30 days of enrollment into this trial;
Other protocol-defined exclusion criteria may apply.

Primary Outcome Measures

Name	Time	Method
Cumulative Dissipated Energy	Day 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 Used	Day 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

Name	Time	Method
Aspiration Time	Day 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.
