Comparison of Surgical Outcomes between Canaloplasty and Schlemm's Canal Scaffold at 24 Months' Follow-Up

The results of canaloplasty (cp) and hydrus microstent (hm) implantation were retrospectively compared at 24 months' follow-up in a cohort of subjects referred to our institution for uncontrolled iop in primary or secondary (e.g.,pseudoexfoliative and pigmentary) open-angle glaucoma. the outcome was labelled as complete success,qualified success,or failure if,two years after surgery,the eyes operated on needed no hypotensive medications,some hypotensive medications,or further glaucoma surgery to attain the target iop,respectively. both cp and hm implant allowed significant iop reductions,with comparable rate of clinical success and safety profile. a slightly (albeit not significant) better trend for a complete clinical success was observed in the cp group. copyright © 2016 stefano a. gandolfi et al.
