简要总结
Retrospective, comparative, interventional, randomized, single-center study, contralateral (the patient's 2 eyes will be implanted: 1 CPO and the other APO) Patients presenting for cataract surgery with a request for presbyopia correction and managed as part of routine clinical practice.
The main aim of the study is to demonstrate that contrast sensitivity is better with the Clareon PanOptix (CPO) intraocular lens (IOL) compared with the AcrySof PanOptix (APO) IOL 3 months after implantation.
详细描述
Visit at Day3-10: usual follow-up visit, no additional examinations as part of the clinical investigation.
Visit at 1 month: usual follow-up visit, no additional examinations as part of the clinical investigation.
3-month visit (end of clinical investigation): usual follow-up visit, plus contrast vision test and non-invasive aberrometry test (I-Trace) as part of the clinical investigation.
Regarding a cataract surgery with a request for presbyopia, the protocol evaluate two differents devices (IOL intraocular lens).
