During trabeculectomy, when a sclerostomy and iridectomy are performed, the structures immediately posterior to the iris, namely the zonules, lens capsule, ciliary processes, and anterior hyaloid face may be violated, resulting in a variety of intraoperative and postoperative complications. Lens injury, including cataract formation, and vitreous prolapse are 2 of the complications that may occur intraoperatively. Cataract formation is one of the most common occurrences after trabeculectomy, reported in approximately 50% of cases. While development of the cataract is usually a slow process, it occurs more frequently in patients with a history of diabetes, postoperative flat anterior chambers, or intraocular inflammation, as well as in a patient with a negative spherical equivalent (preoperative lens status) and pseudoexfoliation syndrome. Older age is a risk factor, since natural cataract development may be accelerated; however, cataracts may develop in up to 25% of younger ( |
