Phacoemulsification,visco-goniosynechialysis,and goniotomy in patients with primary angle-closure glaucoma: A comparative study

Abstract

Objective:

The aim of this study was to evaluate the effects of goniotomy on patients with primary angle-closure glaucoma who underwent “phacoemulsification and visco-goniosynechialysis.”

Materials and methods:

This prospective randomized clinical trial was carried out on 63 eyes of 61 patients (48–85 years) with primary angle-closure glaucoma who were enrolled. The subjects were randomly assigned into two groups. In the first group (32 eyes) and the second group (31 eyes), the patients underwent “phacoemulsification + visco-goniosynechialysis + goniotomy” and “phacoemulsification + visco-goniosynechialysis,” respectively. Intraocular pressure and antiglaucoma medication were evaluated (1 week, as well as 1, 3, and 6 months after the surgery). Anterior segment optical coherence tomography parameters (Casia, Tomey, USA) and goniotomy were evaluated preoperatively and 6 months after the surgery.

Results:

The mean intraocular pressure lowering the effects in the “phacoemulsification + visco-goniosynechialysis + goniotomy” group was higher than that in the “phacoemulsification + visco-goniosynechialysis” group (6.93 and 4.6, respectively). Furthermore, the difference in intraocular pressure between the two groups was significant at 3 months (P = 0.014) and 6 months (P = 0.021) after the surgery. There was no difference in anterior segment optical coherence tomography findings before the intervention; however, after the intervention, the anterior segment optical coherence tomography indices were significantly different between the two groups. Moreover, the difference in “phacoemulsification + visco-goniosynechialysis + goniotomy” indices was more than the changes in the “phacoemulsification + visco-goniosynechialysis” group.

Conclusion:

The results of this study showed that phacoemulsification + visco-goniosynechialysis + goniotomy is a more effective surgery than phacoemulsification + visco-goniosynechialysis alone in undercounted primary angle-closure glaucoma.
