Visco and phacoviscocanalostomy in managing glaucoma patients.

The purpose of this study was to evaluate a nonfiltering glaucoma technique viscocanalostomy alone or in combination with small incision phacoemulzification and intraocular lens (IOL) implantation. From January 1999 to February 2001 viscocanalostomy was performed in 18 patients with medically uncontrolled primary open angle glaucoma. In 10 patients with cataract and primary open angle glaucoma combined operation phacoemulsification and viscocanalostomy was performed. The mean IOP reduction remained statistically significant after 12 months in both groups (p < 0.01). There was also a significant decrease in the antiglaucoma medications in both groups postoperatively. Perforation of trabeculo-Descemet's membrane occurred in two eyes with POAG and the procedure was completed as trabeculectomy, and those patients were excluded from the study. Good hypotensive effect with very low complications rate was achieved. Such a low complication rate makes this operation particularly attractive to surgeons who perform an increasing number of operations in outpatient's bases.
