IOP, gel microstents complications leading cause of reoperation after MIGS

Unanticipated reoperations incidence was low in the first 90 days following minimally invasive glaucoma surgery (MIGS), with the indications for reoperation including elevated IOP and complications with gel microstents, according to a presentation at the 2021 ASCRS Annual Meeting.

In this retrospective case series, 448 MIGS procedures performed on 436 eyes of 348 patients by 6 glaucoma surgeons, were included. Overall, 46% were trabecular microbypass stents, 33.9% were gel microstents, and 20.1% were goniotomies. In 256 eyes (58.7%), combined phacoemulsification was performed.

In 5.3% of eyes, reoperation occurred within 90 days, with 10.5% occurring in gel microstent eyes, 2% in trabecular microbypass eyes, and 3.3% in goniotomy eyes.

Reoperation indications included elevated IOP in 69.6%, gel microstent tip exposure in 13%, lens complications in 13% and early gel microstent encapsulation without elevated IOP in 4.3%.
