Abstract Details

Purpose:

To assess the efficiency of three different methods dedicated to the realization of an optimal capsulorhexis.

Setting:

Hōpital Avicenne (AP-HP), Bobigny, France Hōpital Cochin (AP-HP), Paris, France

Methods:

This prospective study includes 30 consecutive cases of capsulorhexis performed by 2 residents using 1.8mm CMICS phacoemulsification. The population was randomly distributed into 3 groups and the capsulorhexis was done with 3 different devices: Group 1. A single use forceps with the markings at 5,5 (SUE07). Group 2. A standard single use forceps (SUE06). Group 3. A 6mm diameter corneal marker used to draw a guide on the cornea before performing the rhexis with a standard single use forceps (E9036 + SUE06). The following parameters have been analyzed: duration of the rhexis procedure, diameter, centration and regularity of the caspulorhexis, 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.

Results:

There is no difference in capsulorhexis diameter between group 1 and group 2. The caspulorhexis is smaller in group 3. The median Horizontal Caspulorhexis Diameter (HCD) is 5.4mm in group1, 5.42 mm in group 2 and 4.93 mm in group3; the median Vertical Capsulorhexis Diameter (VCD) is 5.3 mm in group 1, 5.35 mm in group 2 and 4.74 mm in group 3. The capsulorhexis size reproductibility is better in group 1 and 3. The HCD standard deviation in mm is 0.27 in group 1, 0.66 in group 2 and 0.24 in group 3. The VCD standard deviation in mm is 0.23 in group 1, 0.59 in group 2 and 0.37 in group 3. The forceps with the markings was judged more comfortable than the corneal marker.

Conclusions:

Circularity, centration and adequate size are different conditions required to create an optimal capsulorhexis. The single use capsulorhexis forceps with the markings has allowed to create a higher-quality capsulorhexis. FINANCIAL DISCLOSURE?: No
