CAPSULAR TENSION RING
OVERALL DIAMETER: 12 mm
CLOSED DIAMETER: 10 mm
OVERALL DIAMETER: 13 mm
CLOSED DIAMETER: 11 mm
Ensures stable conditions during surgery
Circular expansion of capsular bag
Prevents Capsular Fibrosis
Better IOL centration when zonules are missing or damaged
During usage of soft IOLs
Damaged zonules, e.g. cases of Pseudoexfoliatio lentis or different degrees of wearing due to old age
The leading end of the capsular tension ring may entrangle with the bag fornix. This is indicated by traction folds in the posterior capsule. If the end is forcibly pushed father, it may perforate the capsule.
Entanglement occurs more readily with large or rigid capsular tension rings. Such entanglement can be avoided with adequate capsulorhexis sizing and with the use of high viscosity viscoelastic substances.
