Interventions
UNITY® VCS is a CE-marked, FDA-approved ophthalmic microsurgical system that is indicated for both anterior segment (i.e., phacoemulsification and removal of cataracts) and posterior segment (i.e., vitreoretinal) ophthalmic surgery. The focus of this study will be on combined anterior-posterior segments surgery (phacovitrectomy).
CONSTELLATION is a CE-marked, FDA-approved ophthalmic microsurgical system that is indicated for both anterior segment (i.e., phacoemulsification and removal of cataracts) and posterior segment (i.e., vitreoretinal) ophthalmic surgery. The focus of this study will be on combined anterior-posterior segments surgery (phacovitrectomy).
