iStent implantation during cataract surgery reduces IOP in Hispanic cohort

Issue: January 10, 2017

A predominantly Hispanic population with glaucoma had treatment success after iStent implantation during cataract surgery, according to a study.

Researchers included 134 eyes of 100 patients with primary open-angle glaucoma in a retrospective, non-randomized consecutive case series. Each patient underwent combined phacoemulsification and implantation of one iStent trabecular micro-bypass stent (Glaukos). Eighty percent of patients were Hispanic, and 87% had moderate to severe glaucoma.

Mean IOP was reduced from 16.5 mm Hg preoperatively to 12.9 mm Hg at 12 months. Additionally, 92% of eyes had an IOP of 15 mm Hg or less, and 94% of eyes achieved their predefined treatment goal of reduced IOP and medications at 1 year postoperatively.

Seventeen percent of eyes were on three or more medications at 12 months compared with 56% of eyes preoperatively. Additionally, 54% were medication-free compared with 7% preoperatively.

“Not only does this study show the value of using stent technology to safely reduce IOP and medication burden, but it also does so across a demographically diverse patient population with more advanced glaucoma and substantial need for better glaucoma control,” the study authors wrote.
