Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

On the day of surgery, the first eye to be operated is randomised to receive a Vivinex , HOYA Surgical Optics GmbH or an Clareon, Alcon, Fort Worth, Texas. The second eye to be operated receives the other IOL type.

A complete biomicroscopic examination, visual acuity testing using autorefractometer, contrast sensitivity testing, and standardised retroillumination photography for PCO evaluation, will be performed 6 month (30-60 days), 1.5 years (± 3 months) and 3 (± 3 months) years postoperatively.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The investigational devices are approved intraocular lenses (IOLs) intended to be implanted after phacoemulsification in individuals suffering from age-related cataract with the need of cataract surgery. Cataract surgery with precedent bilateral randomized IOL implantation will be performed in subjects who have signed an informed consent form. Postoperative examinations will be implemented in accordance with the approved Investigational Plan on subjects and includes: visual acuity, slitlamp examination, fibrosis, posterior capsule opacification (PCO) score and YAG capsulotomy rate.
