A second non-implant MIGS intervention, namely canaloplasty and trabeculotomy, allows patients to achieve good IOP control if a prior trabecular micro-bypass stent has failed to maintain IOP as desired.
A multicenter retrospective study conducted at five U.S. centers analyzed the outcomes of 27 patients treated with a trabecular micro-bypass stent (iStent or iStent inject, Glaukos) and subsequently with the Omni surgical system (Sight Sciences) due to inadequate pressure control.
Mean IOP decreased from 22.3 mm Hg at baseline to 17.1 mm Hg at 3 months and 17.2 mm Hg at last follow-up; 85% of
