Abstract

Abstract: : Purpose: To evaluate the efficacy of blue light–absorbing intraocular lens (IOL) implantation after cataract surgery. Methods: Thirty–one cataract patients (40–80 yeas old) completed the study per protocol. Patients were implanted blue light–absorbing IOL (ENV–13, MENICON, Group 1: n=16, 71.1±6.7 years old) or ultraviolet–absorbing IOL (ES–13, MENICON, Group 2: n=15, 71.2±6.6 years old), randomly. Three and 12 months after IOL implantation, the mean fluorescein transmittance in vitreous by vitreous fluorephotometry, the cystoid macular edema by fluorescence angiography., and the thickness of fovea by optical coherence tomography were measured. Results: In Group 1, the mean fluorescein transmittance, cystoid macular edema, and the thickness of fovea were 2.83 ng/mL, 25%, and 178.5 µm at 3 months after IOL implantation, 1.07 ng/mL, 9%, and 168.0 µm at 12 months, respectively. In Group 2, the mean fluorescein transmittance, cytosolic macular edema, and the thickness of fovea were 3.02 ng/mL, 28%, and 172.3 µm at 3 months, and 1.12 ng/mL, 17%, and 172.0 µm at 12 months, respectively. Conclusions: These results suggest that blue light–absorbing IOL prevent retinal light damage more effective than ultraviolet–absorbing IOL. And It might be necessary to determine the usefulness of blue light–absorbing IOL, in a future study.
