Assessment of Bleb Morphologic Features and Postoperative Outcomes After Ex-PRESS Drainage Device Implantation Versus Trabeculectomy

Success of Ex-PRESS surgery, as defined in our study, was similar to trabeculectomy. Final IOP measurements were slightly lower after trabeculectomy compared with Ex-PRESS. Differences in some postoperative outcomes faded with follow-up. There remains a need for long-term prospective studies comparing these 2 procedures.
