Abstrakt:	Purpose: To evaluate intraocular lens (IOL) tilt and decentration and their effects on higher-order aberrations (HOAs) after cataract surgery with and without primary posterior continuous curvilinear capsulorhexis (PPCCC). Setting: Fujian Provincial Hospital, Fujian, China. Design: Prospective, intraindividual, randomized, comparative clinical trial. Methods: 64 eyes of 32 patients with age-related cataract who underwent bilateral cataract surgery and IOL implantation were enrolled in this study. In randomized order, all patients had phacoemulsification cataract surgery with PPCCC in 1 eye (PPCCC group) and routine cataract surgery in the contralateral eye (NPCCC group). IOL decentration, tilt, HOAs, modulation transfer function, and point spread function were measured at 1 day, 1 week, 1 month, and 3 months after surgery using OPD-Scan III. Results: 52 eyes of 26 patients were available for analysis. The mean overall decentration in the NPCCC group was significantly higher than in the PPCCC group at 3 months (0.302 ± 0.157 mm vs 0.187 ± 0.099 mm, P < .001). Under 3 mm pupil, internal spherical aberration (SA) 1 day after surgery and coma 1 week after surgery were lower in the PPCCC group compared with the NPCCC group (0.15 ± 0.10 μm vs 0.30 ± 0.21 μm, P < .001, and 0.34 ± 0.18 μm vs 0.47 ± 0.31 μm, P = .03, respectively). IOL decentration was significantly correlated with ocular and internal coma, ocular and internal SA, and internal HOAs at 5 mm pupil ( R = 0.083 and R = 0.099, R = 0.650 and R = 0.613, and R = 0.418, respectively, all P < .01). Conclusions: Less IOL decentration was observed in the PPCCC group at 3 months after surgery, indicating that PPCCC may result in better IOL centrality. (Copyright © 2023 The Author(s).
