Circular Anterior Lens Capsule Rupture Caused by Blunt Ocular Trauma

A 16 year old male experienced blunt ocular trauma causing rupture of the anterior lens capsule and mature cataract development. The trauma was due to a stone that impacted the left eye. In an otherwise clear lens, an anterior lens capsule defect formed post-trauma that progressed to a mature cataract over four months reducing distance vision from 20/125 to hand motion. The patient underwent phacoemulsification with posterior chamber intraocular lens implantation in the left eye. One year postoperatively, the vision in the left eye increased to 20/25 without correction. This is a rare case of cataract formation due to a defect in the anterior lens capsule caused by blunt ocular trauma.
