CAPSULAR TENSION RING

VISIRING

ADVANTAGES

  • Ensures stable conditions during surgery

  • Circular expansion of capsular bag

  • Prevents Capsular Fibrosis

  • Better IOL centration when zonules are missing or damaged

INDICATIONS

  • OL subluxation

  • During usage of soft IOLs

  • Damaged zonules, e.g. cases of Pseudoexfoliatio lentis or different degrees of wearing due to old age

PRECAUTIONS

  • 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.
