New capsular tension segment with 2-point fixation for zonular weakness. | LitMetric

New capsular tension segment with 2-point fixation for zonular weakness.

J Cataract Refract Surg

From the John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.

Published: May 2017

AI Article Synopsis

Article Abstract

We describe clinical applications and surgical techniques for a new type of capsular tension segment (CTS) for use during cataract surgery. The Ambati CTS is distinguished from other CTS devices by having 2 eyelets close to each other, which allows it to distribute tension to 2 points, avoiding too much stress at a single point on the anterior capsulotomy, which prevents peaking of the capsulorhexis, and potentially reducing the risk for anterior capsule tear. Two of these CTS devices could possibly be used to provide 4-point fixation of a capsular bag in eyes with near-complete zonular instability. We describe 4 cases and 2 surgical techniques for implanting the new CTS, 1 technique in an adult patient with zonular weakness secondary to trauma and the other in 3 children with subluxated lenses due to Marfan syndrome.
