For both groups, the IOL-PC space became smaller between the follow-up visits on the first day and 1 month after surgery (
Fig. 3). For the IQ group, the area of the IOL-PC space was 0.72 ± 0.35 mm
2 at 1 day after surgery, and 0.40 ± 0.24 and 0.23 ± 0.16 mm
2 at 1 week and 1 month after surgery, respectively (
Fig. 4). For the AO group, the area of the IOL-PC space was 0.19 ± 0.34 mm
2 1 day after surgery, and 0.02 ± 0.05 and 0.01 ± 0.02 mm
2 at 1 week and 1 month, respectively. At each of these times, the values for the AO group were significantly smaller (
P < 0.001,
Fig. 4A). For both groups, the IOL-PC space became significantly smaller between the first and seventh postoperative days (
P < 0.001 for the IQ group,
P = 0.038 for the AO group, Fig. 4A). For the IQ group, the space continued to narrow between 1 week and 1 month after surgery (
P < 0.001,
Fig. 4A); however, for the AO group, the IOL-PC space was almost nonexistent at 1 week; therefore, no significant change in the area of IOL-PC space occurred between 1 week and 1 month (
P = 0.150,
Fig. 4A). Thus, the speed with which the space became smaller differed for the IQ and AO groups. No eye in the IQ group had complete contact between the IOL and the capsule at 1 month after surgery. In contrast, in the AO group, complete closure between the IOL and the capsule was observed in 4 eyes (26.7%) at 1 day (
P = 0.010), 11 eyes (73.3%) at 1 week (
P < 0.001), and 13 eyes (86.7%) at 1 month (
P < 0.001).
