The purpose of the study is to compare the efficiency and safety of UNITY™ Vitreoretinal Cataract System (UNITY VCS) to CENTURION® Vision System with Active Sentry (CAS) in adult subjects with grade 2 or greater nuclear sclerotic cataracts who require phacoemulsification in both eyes. Subjects will attend a total of 8 scheduled visits for an individual duration of participation of approximately 1 month.

Detailed Description

In this contralateral eye clinical study, one eye will undergo surgery with UNITY VCS and the other eye will undergo surgery with CAS. The second eye surgery will occur 0 to 14 days after the first eye surgery.
