The Effect of a Blue Light Filtering IOL

Overview

To compare the effect on blood retinal barrier disruption 3 and 12 months after implantation of either a blue light filtering intraocular lens(blue-filtering IOL) or an ultraviolet light filtering intraocular lens(UV-filtering IOL).

The following parameters were measured for evaluation of blood retinal barrier disruption. * the incidence of macular leakage by fluorescence angiography (FA) * the mean fluorescein concentration in the vitreous by fluorophotometry (VFP) * the thickness of the macula by optical coherence tomography (OCT) Results * the incidence fo macular leakage decreased significantly from 24%(3 months) to 5% (12 months) in the blue-filtering IOL group (P\<0.05), and was significantly lower compared with the UV-filtering IOL group at 12 months. * the VFP significantly decreased in both group from 3 to 12 months. * the OCT decreased from 175 (3 months) to 166 um (12 months) in the blue- filtering IOL group.
