Design of an intraocular lense with improved peripheral vision

Abstract

The fast development of IOLs has provided patients with optical performance that more closely resembles that of the healthy human eye, however such optical performance experience is achieved only for on-axis (0 degrees) optical performance, leaving the peripheral vision inferior to the health human eyes.. Recently, studies have demonstrated the importance of peripheral vision to patients' daily life. To solve this problem, an IOL with improved peripheral vision has been proposed. The IOL is designed to optimize peripheral vision in a 40-degree field of view (FOV) under 3 mm pupil diameter, while maintaining on-axis optical performance. The design results shows that the designed IOL provide the same level of central field optical performance compared to healthy human eyes and traditional IOLs as well as the improving peripheral vision. This IOL design may help to reduce the risks related to peripheral vision loss in daily life.
