Brief summary

The purpose of this study is to assess the accuracy of intra ocular lens power calculation using the new Carlevale sutureless scleral fixation posterior chamber intra ocular lens.

Detailed description

Retrospective comparison of refractive spherical equivalent predicted before surgery and measured after surgery in patient who underwent implantation of an sutureless scleral fixation posterior chamber intra ocular lens between October 2019 and Avril 2022 in the ophthalmology department of Poitiers Hospital and La Rochelle Hospital.
