AMSTERDAM — Asymmetric multifocal technology has become popular in Europe, according to Sunil Shah, MD, FRCOphth, who spoke at the European Society of Cataract and Refractive Surgeons meeting.

“The challenge is in trying to improve this [technology],” which is intended to offer more contrast, color, light and balanced vision, Shah said.

Building on the foundations of its predecessor lens, the Lentis MplusOculentis has introduced its next rotationally asymmetric segmented multifocal IOL, the Lentis Mplus X, Shah said.

One difference in design is that “the segment is slightly bigger by about 4 degrees” to increase the central area and allow improved reading acuity, improved pupil independence and increased depth of focus, Shah said.

In a study of 20 patients of cataract age who underwent implantation of the Mplus in one eye and MplusX in the other eye, at 3 months Shah and colleagues found patients to have “across the board, a significant improvement in intermediate and also in near” visual acuity with implantation of a +3 MplusX IOL, Shah said.
