Capsular Support: Rings, Hooks, and More

June 2022 Update

Zonular weakness can be a cause for concern in cataract surgery, increasing the risk of complications such as lens dislocation and posterior capsule rupture. In order to avoid such complications, capsular support devices can be used to improve capsular bag stability and centration. In the case of total lack of capsule support, options such as anterior chamber placement or fixation techniques may be required. 

In this updated ASCRS Focus on Cataract Surgery, explore educational resources about the variety of capsular support devices available to today's cataract surgeon.

Flanged iris hook technique for capsular bag stabilization

Journal of Cataract & Refractive Surgery: June 08, 2022 - Volume - Issue - 10.1097/j.jcrs.0000000000000985

A novel surgical technique was demonstrated for fixating the capsular bag to the sclera using a capsule tension segment (CTS) and a flanged iris hook. In a patient with 180-degree zonular dialysis, a capsule tension ring was implanted in the capsular bag, and a CTS was placed in the zonular dialysis area after the cataract removal.
