[ProVisc--a new viscoelastic material for surgery of the anterior segment. A multicenter clinical study]

Within the framework of a multicentric clinical study which was implemented at nine selected departments a new viscoelastic material ProVisc of Alcon company was tested during extracapsular extraction of cataract with implantation of posterior chamber intraocular lenses. A total of 100 eyes of 100 patients were operated and all pre- and postoperative data were recorded in uniform protocols. The selection of suitable patients and the type of surgical procedure was within the responsibility of the surgeon. The type and frequency of surgical and postoperative complications was similar as when other viscoelastic material ProVisc can be recommended as safe and effective in modern surgery of cataract.
