Multifocal IOLs

When cataracts are removed the natural lens of the eye is replaced with an artificial intraocular lens (IOL). Ideally a multifocal IOL allows cataract patients to have good distance vision and read without the aid of glasses. A recent study compared multifocal IOLs for reading in different lighting conditions.

Three IOLs, the SA40N and the Tecnis ZM001, both made by Advanced Medical Optics (AMO), and the AcrySof ReStor SA60D3 made by Alcon, were used in the study. 60 patients were involved. The Tecnis provided the best reading in low light. In bright lighting the Tecnis and the Acrysof ReStor provided better reading than the SA40N. Of the three, the Tecnis provided reading acuity and speed in the most versatile lighting conditions.
