Description :

Designed by Ike Ahmed, M.D.

The Ahmed Capsular Tension Segment (CTS) for scleral fixation is indicated for patients with extensive and/or progressive zonular loss. The partial ring segment traces a 120º arc with a radius of 4.5 or 5.0 mm and an anteriorly positioned fixation eyelet. Unlike CTRs, the CTS can be used in cases where an anterior or posterior capsular tear or a discontinuous capsulorhexis is present, as it does not generate a 360º expansile force. Multiple segments can be used if necessary. The CTS provides support in the area of fixation. It has to be combined with a CTR when circumferential support is required. The CTS may also be used for intraoperative support and removed prior to completion of the surgery.
