Abstract. 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.

Traumatic cataracts characteristically take one of three forms. Commonly, a circumscribed, rosetteshaped opacity is found in the anterior cortex. Histology reveals these opacities to be vacuolated intercellular spaces, associated with degenerated lens fibers.1 Second, one might observe a Vossius' ring opacity, associated with epicapsular pigment deposition.2 Third, the opacities may be diffuse, secondary to larger breaks in the lens capsule.1·2 We detail two cases of traumatic cataract and propose a plausible explanation for the posterior capsular breaks that we observed.
