Enhanced safety of cataract surgery - active control of intraocular pressure and improved fluid distribution

Abstract

Since the introduction of pioneer phacoemulsification by Kelman, it is observed constant improvement of phaco systems with regard to their safety and efficiency. The present paper is to present contemporary advances in systems of phacoemulsification of cataract, showing in details new technological achievements of Centurion Vision System (Alcon Laboratories, Fort Worth, TX, USA). Compared to other previous systems main progress is as follows: improved cassettes provide much more stable fluidics during surgery, new system providing stable IOP in the anterior chamber and newly designed balanced tip that limits energy production in the wound. Preliminary own experience is encouraging, however, prospective studies are needed to establish and compare the influence of the new system on some outcome measures (e.g. BCVA, corneal thickness, endothelial density, tyndalometry).
