27 EWAP CATARACT/IOL March 2014 A. John Kanellopoulos, MD , clinical professor of ophthalmology, New York University, New York, and director of Laser Vision, GR Institute, Athens, Greece, has had experience with the predecessor technology to the Cetus over the last 15 years and has published several feasibility studies in the past on laser cataract surgery. 1,2 He recently combined the use of femtosecond laser-assisted corneal incisions, capsulotomy and lens fragmentation with the LenSx laser (Alcon, Fort Worth, Texas, U.S.), and emulsification of the lens fragments with the Cetus nanosecond laser, bypassing the need for phacoemulsification utilizing traditional ultrasound phaco technology. In a recent publication he compared femto plus phaco to femto plus nano laser in the study of the contralateral eyes of a 57-year-old female patient who underwent LenSx and phacoemulsification in one eye and LenSx and Cetus in the other. Total energy used was found to be 6 J by phacoemulsification and only 2.4 J by Cetus. Both eyes achieved 20/20 vision at six months. Copious viscoelastic material, however, was required during the Cetus procedure in order to pre-chop the cataract fragments and complete their separation started with the femto laser. 3 These differences in energy required may contribute to significant endothelial cell preservation and reduction in postoperative inflammation, both significant parameters in cataract surgery.
