Abstract

BACKGROUND:

Although the open capsular tension ring was designed to manage zonular dialysis during cataract surgery, it also lowers the incidence of capsule contraction, stabilizes the capsular bag, and enhances IOL centration. With appendages, it provides a partial solution for those eyes with colobomata and aniridia. MATERIALS AND TECHNIQUES: Subsequent modifications to the capsular tension ring include the Cionni ring, capsular edge ring, coloboma ring, and aniridia ring. A square-edge design may inhibit posterior capsule opacification, and the aniridia and coloboma rings with appendages create an artificial it is in traumatic or congenital colobomata.

RESULTS:

Designs, functions, indications, and results of different types of capsular tension rings are reviewed, as well as applications in pediatric cases, and considerations for their routine use in adult cataract surgery.

CONCLUSIONS:

The potential benefits of capsular edge ring implantation in pediatric cataract surgery cases are explored.
