Intraoperative and Postoperative Outcomes of Three Ophthalmic Viscosurgical Devices During Phacoemulsification

August 13, 2012 updated by: Iladevi Cataract and IOL Research Center
Ophthalmic Viscosurgical Devices (OVDs) play a crucial role during phacoemulsification, by providing endothelial protection, maintaining space, as well as facilitating surgical maneuvers, including IOL implantation. Equally important is the ease of use, good visualisation and easy removal of the OVD from the eye. Currently, 3 popularly used OVDs as a single injection sufficing for surgery are: Healon 5, DiscoVisc, and Celoftal (2% hydroxypropylmethylcellulose). Whereas, there are studies showing efficacy of each of these in clinical scenarios, there is no randomized trial comparing intraoperative performance and postoperative outcomes. The aim of this study was to compare intraoperative performance and postoperative outcomes following microcoaxial phacoemulsification when using one of the three OVDs
