Review and comparison of femtosecond laser systems

Three companies, OptiMedica, LenSx (acquired by Alcon in September 2010), and LensAR, in different stages of U.S. Food and Drug Administration clearance, are developing femtosecond laser systems for cataract surgery. These systems will create the initial corneal incisions, capsulotomy, and also fragment the lens. This article outlines the advantages of femtosecond laser cataract surgery and provides an initial comparison of the LensAR, LenSx/Alcon, and OptiMedica systems and early clinical results.
