[Continuous circular capsulorhexis in extracapsular cataract extraction].
To investigate clinically the advantage, method and prevention of complication continuous circular capsulorhexis, a surgery consisting of continuous circular capsulorhexis, extracapsular cataract extraction and one-piece PMMA intraocular lens (IOL) implantation was performed on 52 eyes. The control was "canopener" capsulotomy made in 40 eyes. The residual anterior capsule and loop fixation of IOL were observed by dilatation of the pupil and gonioscopy 1 month after the operation.


RESULTS
Postoperatively an anterior capsular opening of 6.5 approximately 7.0 mm in diameter with sharp edge could be seen in 48 eyes and the fixation of both loops in the capsular bag was found in 44 eyes (84.6%) in capsulorhexis group and 21 eyes (52.5%) in "canopener" capsulotomy group. It is demonstrated that continuous circular capsulorhexis could maintain the integrity of the capsular bag and increase the chance of achieving a fixation of IOL in the bag.
