Effectiveness and Safety of Combined Ab-Interno Canaloplasty and Microstent Implantation in Severe Glaucoma A Retrospective Study

Key Points

A significant mean intraocular pressure reduction of 9.8 mmHg was observed post-surgery, indicating effectiveness in treatment.
The mean number of glaucoma medications decreased by 47%, highlighting a reduction in medication burden for patients.
In a retrospective analysis over 27.9 months, no intraoperative complications were reported, suggesting safety of the combined procedure.
Postoperative intraocular pressure often remained above target levels, indicating limitations in achieving very low pressure in advanced cases.

Abstract

Justin Spaulding Cataract â 40%, p< 0.001). No intraoperative or postoperative complications were reported; 6 eyes (9%) required additional glaucoma procedures during follow-up.Conclusion: Combining ab-interno canaloplasty with Hydrus Microstent implantation during cataract surgery resulted in modest but sustained reductions in intraocular pressure and glaucoma medication burden, with a favorable safety profile. However, postoperative IOP frequently remained above levels required for very low target pressures. These findings suggest that this mixed MIGS approach may be considered in carefully selected patients but should not be viewed as a substitute for traditional filtering surgery in advanced disease.Keywords: primary open-angle glaucoma, minimally invasive glaucoma surgery, MIGS canaloplasty, Hydrus Microstent, combined MIGS, IOP reduction
