Blue-Blocking IOLs in Combined Surgery

The Ludwig Boltzmann Institute of Retinology and Biomicroscopic Laser Surgery60 enrolled

Overview

Although commonly used in cataract surgery, the use of the blue light-filter IOLs in vitrectomy combined with cataract surgery has not been reported yet. A prospective controlled clinical trial was designed to evaluate the effect of the blue light-filter IOL on the surgeon's ability to perform specific vitreoretinal procedures and on the patients' outcome.

Sixty patients were randomly assigned to receive a UV-filter IOL (transparent IOL group) or a blue light-filter IOL (yellow IOL group) combined with a vitreoretinal procedure. Outcome measures were intraoperative conditions for the surgeon, complication rates, the functional outcome and vitreoretinal diagnoses.
