Traumatic Cataract

Thomas A. Oetting, MS, MD

This patient had blunt trauma which resulted in a cataract and mydriasis. We removed his cataract and placed a capsular tension ring just prior to placing the IOL. Then we placed 2 10-O Prolene sutures in the iris, one at 3 and one at 9 o'clock, to lessen the mydriasis. We used the Siepser sliding knot technique to tie the suture with Prolene suture.

(please see for a more descriptive video of the Siepser technique)
