The objectives of the study is to evaluate efficacy and long-term safety of the Lucidis lens. Through this study, the objective is to obtain an up-to-date clinical evaluation of the medical device thus supplementing data from experimental trials. Clinical and functional changes in the implanted eyes among a patient population in which the opaque crystalline lens resulting from cataract was removed and replaced by a Lucidis IOL will be described.

Refractory function in patients with a cataract is mainly restored by implanting intra-ocular lenses (IOL) destined to replace the crystalline lens. While new surgical techniques for removing the crystalline lens have been developed, these lenses have been considerably perfected to resemble the natural crystalline lens as closely as possible.
