Optical bench performance of 3 trifocal intraocular lenses

Purpose To compare the optical performance of 3 trifocal intraocular lenses (IOLs): the Acrysof IQ Panoptix (+2.17 diopter [D]/+3.25 D IOL), AT LISA Tri 839MP (+1.66 D/+3.33 D IOL), and Finevision Micro F (+1.75 D/+3.50 D IOL). Setting Alcon Research Ltd., Fort Worth, Texas, USA. Design Experimental study. Methods The 3 trifocal IOLs were compared using optical performance tests. To measure image quality, through‐focus modulation transfer function (MTF) curves were generated for a model eye. To assess resolution, through‐focus Badal images of an Early Treatment Diabetic Retinopathy Study chart simulating viewing distances of infinity to 40 cm were recorded. To measure photic phenomena, simulated headlight images with a 50 &mgr;m pinhole target and a 5.0 mm pupil were obtained. Results The MTF measurements showed similar near and distance peaks for the IOLs, but the optimum intermediate peak for the +2.17 D/+3.25 D IOL was 60 cm versus 80 cm for the other 2 trifocal IOLs. Similarly, in bench Badal image testing, the optimum intermediate image was at 60 cm for the +2.17 D/+3.25 D IOL and 80 cm for the other 2 IOLs. Overall, halos surrounding simulated headlight images were equivalent for the 3 IOLs. Conclusions In bench studies, the new +2.17 D/+3.25 D trifocal IOL showed equivalent or better performance in image quality, resolution, and photic phenomena compared with the +1.66 D/+3.33 D and +1.75 D/+3.50 D trifocal IOLs. The new IOL is expected to provide better intermediate vision at 60 cm, which is preferred for real‐life tasks such as computer work, over the 80 cm intermediate distance offered by the other 2 trifocal IOLs.
