Registry of PHAcoemulsification for Cataract Surgery

Cataracts cause vision loss due to opacities in the lens. Cataract surgery is performed by emulsifying the nucleus of the lens. A phacoemulsifier is the machine used to deliver ultrasonic energy in the eye to fragment the lens and aspirate the debris. In contrast to the large number of cataract procedures performed worldwide, there is surprisingly scarce data regarding the intraoperative parameters used during phacoemulsification. As new technologies are made available to surgeons, this impedes a large-scale analysis of the benefits of the advances in phacoemulsifiers. The investigators aim to establish a nationwide registry with a database of intraoperative data recorded during the cataract procedures performed with the Centurion phacoemulsifier. The data collected would encompass all parameters recorded in the phacoemusifiers' logs, such as the energy delivered in the eye (longitudinal, torsional and other), US time, BSS volume, duration of the procedure, surgeon settings and others. The objective will be to capture data from at least 100,000 procedures/year.
