Traumatic cataract and Wieger's ligament.

The objective of this study was to determine the relationship between posterior subcapsular contusion cataract and Wieger's ligament. Two clinical cases of traumatic cataract, occurring in young patients, were analyzed. In neither case was there evidence of penetrating or perforating injuries to the globe. During cataract extraction a smooth oval defect in the posterior capsule was observed; however, there was no evidence of intraoperative capsular damage. The outline of the defect was consistent with the border of Wieger's ligament. It appears that blunt trauma avulsed this region of lens capsule, resulting in these findings.
