Abstract

Purpose

To compare 12-month clinical results of spatula-shaped and dual-blade microhooks ab interno trabeculotomy with phacoemulsification.

Study design

Retrospective comparative study.

Methods

We conducted a retrospective chart review of Japanese open-angle glaucoma patients who underwent ab interno trabeculotomy with phacoemulsification with a 12-month follow-up. Two types of trabecular hook were used: the spatula-shaped Tanito Trabeculotomy ab interno Micro-hook® and the Kahook Dual Blade®. Changes in intraocular pressure (IOP) and medication scores comprised the main outcome metrics. We also analyzed and compared patient demographics and the occurrence of complications.

Results

Trabeculotomy was performed using a spatula-shaped hook in 17 eyes and a dual-blade hook in 15 eyes. Significant reductions in IOP (p < 0.001) and medication scores (p < 0.001) were noted in both groups after the 1-month time point. The percentage changes of IOP from baseline at each time point were not significantly different between groups, though there was a significant difference in medication scores at 12 months (p = 0.0192). Postoperative complications occurred similarly in both groups; one case in the dual-blade group required additional filtration surgery.

Conclusions

Ab interno trabeculotomy with phacoemulsification was effective in lowering IOP both with spatula-shaped and with double-blade microhooks. At 12 months more medications were used postoperatively in the spatula-shaped microhook group; however, the reductions in the medication scores from baseline were statistically significant in both groups.
