a Schematic of the lens caliper (LC)-assisted capsulorhexis. Before performing capsulotomy, the surgeon uses the LC to measure and locate the position of capsulorhexis with 5.3 mm diameter, create 8 key markers of capsulorhexis path on the lens anterior capsule using the blunt head of the LC, and then carry out capsulotomy according to the marks. b Clinical application of the LC to assist capsulorhexis. c The performance of capsulorhexis assisted by LC was compared with that for experience-based capsulorhexis. LC-assisted capsulorhexis dramatically improved the centralization of CO and the alignment of capsulorhexis and the IOL. d The average horizontal and vertical diameters of the experience-based COs were larger than those of the LC-assisted COs, which were closer to the size of the ideal opening. e LC assistance also effectively reduced the proportion of overlarge COs. f LC assistance significantly increased the ratio of complete capsulorhexis-IOL overlap, and decreased the ratio of partial IOL overlap. g LC-assisted capsulorhexis dramatically enhanced the rate of ideal COs.
