PRECAUTIONS	The leading end of the capsular tension ring may entangle with the bag fornix. This is indicated by traction folds in the posterior capsule. If the end is forcibly pushed farther, 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.
