This Clinical Trial Compares Two Phacoemulsification Systems Used in a Bilateral Cataract Surgery Subjects in Order to Study CDE and Ultrasound Time During Cataract Removal

Inclusion Criteria:

• Healthy patients 18 years or older undergoing uncomplicated sequential bilateralcataract surgery with phacoemulsification and IOL implantation

• Expected to undergo sequential cataract surgery in both eyes

• Must have bilateral nuclear sclerosis cataracts classified using LOCS III as grade 3or above (see appendix III)

• Both eyes will be operated on by the same surgeon

• Have the ability to consent for study and procedure planned

Exclusion Criteria:

• Patients under 18 years of age.

• Complex cataract cases involving zonulopathy (e.g., pseudoexfoliation syndrome,traumatic zonular weakness) that may require use of zonular support devices duringsurgery (e.g. capsular hooks) and/or implantation of capsular tension rings or otherzonular support devices, and in the investigator's judgment, may interfere with thesurgical procedure or study outcome measures.

• Require mechanical pupil expanding devices (e.g., iris hooks, Malyugin rings, etc.)

• Undergoing femtosecond laser-assisted lens fragmentation.

• Surgical complications, in the opinion of the investigator, occurring eitherintraoperatively or postoperatively (including capsule tears, iris trauma, ordecentered intraocular lens) and not attributable to the study device or studydesign.

• Prior ocular surgery (including intraocular, oculoplastic, corneal or refractivesurgical procedure) performed within the last 3 months or at any time that in theinvestigator's clinical judgment, if it interferes with the outcome measures of thisstudy.

• Presence of endothelial cell dystrophies and/or corneal comorbidities.

• History of intraocular inflammation (e.g., uveitis, iritis).

• History of retinal edema or presence of a clinically significant epiretinal membranethat, in the investigator's clinical judgment, may interfere with the outcomemeasures of this study.

• History of retinal surgery (e.g.retinal detachment repair, membrane peel) involvingvitrectomy.

• Dense brunescent cataract that in the investigator's clinical judgment, mayinterfere with the outcome measures of this study.
