In the the last few months, forceps dedicated to CMICS incision have been developed. In a previous study, we have shown a high level of efficiency and safety, and no major difficulties, using this kind of device. However, we did not evaluate then the capsulorhexis quality created with these forceps.

We performed a propspective study including 36 consecutive cases of capsulorhexis performed by 2 residents using 1.8 mm CMICS phacoemulsification. The population was randomly distributed into 3 groups and the capsulorhexis was done using 3 different devices (Figures 1–3):

The following parameters have been analysed: diameter, centration and regularity of the caspulorhexis, duration of the rhexis procedure as well as intraoperative complications (capsular tear, posterior capsule rupture). The subjective degree of difficulty in creating an optimal capsulorhexis was also evaluated using a questionnaire.

Study shows reproducibility with devices dedicated to standardizing capsulorhexis
