Intermediate Outcomes of SIBS Microshunt, Gelatin Microstent and Trabeculectomy: A Comparative Retrospective Cohort Study.

SIBS microshunt group included a significantly higher proportion of eyes with prior failed glaucoma filtering surgery (41.9% vs 0% for gelatin microstent and 2.8% for trabeculectomy, respectively; p<0.001).

Qualified success was achieved in 83.7%, 66.7%, and 55.6%, respectively, with SIBS demonstrating superior outcomes than gelatin microstent (p=0.003).

In the multivariable analysis, the gelatin microstent (HR 3.43; 95%CI 1.61-7.31), and combined cataract surgery (HR 2.06; 95%CI 1.27-3.35) were associated with increased hazard of failure, while age ≥70 years was associated with lower risk of failure (0.54; 95%CI 0.30-0.98).
