Description :

The Ahmed Segment is designed by Ike Ahmed, MD. This partial ring is indicated for significant zonular weakness and may be used intraoperatively or as permanent support.

The Ahmed Segment is a modified design of the Cionni CTR that covers approximately one quadrant with a hole for temporary or permanent fixation.

One or more segments may be used as necessary to support the areas of the capsule that have damaged or insufficient zonular support. Because it is only a segment, placement is easy and atraumatic, even before phacoemulsification. There are no sharp points or edges to tear the capsulorhexis and removal is easy. According to Dr. Ahmed, stripping cortex out from under and around the segment is easy. It can be used even when anterior or posterior capsular tears are present.
