Comparison of Maximum Stretch Forces between Femtosecond Laser-Assisted Capsulotomy and Continuous Curvilinear Capsulorhexis

Figure 4

Results of the capsule stretch experiments. Association between stretch distance and stretch forces during the capsule stretch experiments in the CCC group (a) and FLC group (b) is shown. There were large variations in maximum stretch force and maximum stretch distance within the CCC group, while there was less variation in the FLC group in this regard. The average maximum stretch force and the coefficient of variation (CV) in each group are shown (c). There were no differences in mean stretch force between the CCC group and the FLC group (d). However, the middle CCC subgroup showed higher stretch forces than the FLC group (e). .
