Three-year outcomes of trabeculectomy and Ahmed valve implant in patients with prior failed filtering surgeries.

Purpose: To compare three-year surgical outcomes of trabeculectomy versus Ahmed valves in patients with prior failed trabeculectomy.

Methods: This is a longitudinal retrospective comparative study of one-hundred twenty adult patients with prior failed trabeculectomy who underwent a repeat trabeculectomy or Ahmed valve implant. Demographic and clinical data were collected up to 3 years on all study participants at the Kresge Eye Institute from 2004 to 2016.

Factors Associated with the Development of Posterior Capsule Opacification Requiring Yttrium Aluminum Garnet Capsulotomy.

Significance: Determining risk factors for posterior capsule opacification will allow for further interventions to reduce the risk of development and thus additional procedures.

Purpose: The purpose of this study was to investigate risk factors associated with development of clinically significant posterior capsule opacification requiring yttrium aluminum garnet (YAG) capsulotomy.

Methods: Medical records of patients (≥18 years) who underwent cataract surgery between January 1, 2011, and March 31, 2014, at Kresge Eye Institute were reviewed.
