Adding iAccess goniotomy to cataract surgery with iStent shows promising IOP reduction at one month
Adding iAccess goniotomy to cataract surgery with iStent inject provides a significantly greater reduction in intraocular pressure at 1 month compared to the standard procedure, though the difference is not significant at 1 year, according to a presentation at the 2025 ASCRS Annual Meeting.
The retrospective case series followed 281 eyes over a year, comparing 166 standard combined procedures with 115 cases that included 3 goniotomy trephinations.
Both groups had similar preoperative characteristics, including mean visual acuity (20/40), cup-to-disc ratio (0.7 ± 0.1), and intraocular pressure. At 1 month, the iAccess group demonstrated a significantly greater reduction in IOP (3.8 ± 5.1 mmHg) compared to the standard group (2.4 ± 5.2 mmHg), with no changes in medication use. Although this trend continued at 12 months, the difference was not statistically significant.
