Trial Following Subjects Bilaterally Implanted With Mini Well Ready For 2 Years After the Second Eye Implant

Study Overview
=================
Brief Summary
-----------------
The study objective is to evaluate the visual performance of MINI WELL Ready at 24 months following the second eye implant. The objectives of safety are to evaluate the rate of Secondary Surgical Interventions related to the optical properties of the IOL for first and second operative eye separately at 24 months and the rate of visual disturbances and distortions as reported by the subjects as detected by using the Halo & Glare Simulator.

Detailed Description
-----------------
The present post-.market follow-up study (PSM8 sub-study) is an ancillary study of the PSM8 post market clinical trial (NCT02740010)
