Patients and methods: In this prospective study, patients with cataracts were randomized to an OVD, and then received phacoemulsification and injection of an intraocular lens. After each surgery, unmasked investigators completed subjective questionnaires about OVD characteristics during each stage of the procedure. Masked technicians evaluated objective safety parameters of intraocular pressure (IOP) and endothelial cell density, with 90 days of follow-up. Results: The DisCoVisc OVD group (128 eyes) and the Healon OVD group (121 eyes) had statistically similar outcomes for IOP and for endothelial cell loss. Subjectively assessed viscosity was statistically different (P &lt; 0.0001), with Healon OVD most often rated &ldquo;cohesive&rdquo; and DisCoVisc OVD most often rated &ldquo;both dispersive and cohesive&rdquo;. Workspace maintenance differed between groups (P &lt; 0.0001), with workspace most frequently rated &ldquo;full chamber maintained&rdquo; when using DisCoVisc OVD and most frequently rated &ldquo;workspace maintained&rdquo; when using Healon OVD. &ldquo;Flat&rdquo; or &ldquo;shallow&rdquo; workspace ratings occurred only in the Healon OVD group. Conclusion: DisCoVisc OVD had both cohesive and dispersive properties, and was safe and effective for every stage of cataract surgery.
