The preventive effect of capsular tension ring in phacoemulsification of senile cataracts with pseudoexfoliation.

We evaluated the preventive role of the capsular tension ring (CTR) in zonular and capsular complications in the phacoemulsification surgery of cataracts with pseudoexfoliation (PEX) in two groups of eyes with senile cataract associated with PEX, with (Group A) or without (Group B) CTR implantation. CTR implantation did not prove as effective as expected in preventing the zonulo-capsular complications. Contradictory to the significant increase of intracapsular intraocular lens (IOL) implantation rate, post-operative visual acuity did not improve in the same value.
