Abstract：
UNASSIGNED: This study aimed to compare early changes in classified higher-order aberrations (HOAs) pre- and postsurgery in patients who received nontoric versus toric implantable collamer lenses (ICL; ICL Model V4c; STAAR Surgical, Monrovia, CA, USA).
UNASSIGNED: This prospective study included 124 eyes of 64 patients: 49 eyes were treated using a nontoric implantable collamer lens (ICL), and 75 eyes were treated using a toric implantable collamer lenses (TICL). Refractive parameters and ocular aberrations were examined before and 1 month after surgery.
UNASSIGNED: At one month, the safety indices were 1.24 ± 0.17 in the ICL group and 1.20 ± 0.25 in the TICL group (p = 0.39). The efficacy indices were 1.07 ± 0.17 in the ICL group and 1.15 ± 0.26 in the TICL group (p = 0.02). The root mean square (RMS) values of whole-eye total HOAs, trefoil, corneal total HOAs, spherical aberration, and intraocular spherical aberration significantly increased postoperatively in both groups. The RMS of intraocular total HOAs in the TICL group significantly increased 1 month postoperatively. No statistically significant differences were observed in HOA changes between the ICL and TICL groups.
UNASSIGNED: The dominant increases in short-term aberrations after ICL and TICL V4c implantation were in corneal trefoil and intraocular spherical aberrations, which were related to the corneal incision and implanted lens. The HOA changes post-surgery were not statistically different between the two lens types.

摘要：
■本研究旨在比较接受非复曲面和复曲面可植入晶状体（ICL；ICL模型V4c；STAAR外科，蒙罗维亚,CA,美国）。
■这项前瞻性研究包括64名患者的124只眼：49只眼使用非复曲面可植入结晶体（ICL）治疗，使用复曲面可植入Collamer晶状体（TICL）治疗75只眼。手术前和手术后1个月检查屈光参数和眼像差。
■一个月后，ICL组和TICL组的安全性指数分别为1.24±0.17和1.20±0.25(p=0.39).ICL组为1.07±0.17,TICL组为1.15±0.26(p=0.02)。全眼总HOA的均方根(RMS)值，三叶,角膜总HOAs,球面像差,和眼内球面像差均在术后显著增加。TICL组眼内总HOA的RMS在术后1个月显著增加。在ICL和TICL组之间的HOA变化没有观察到统计学上的显著差异。
■ICL和TICLV4c植入后短期像差的主要增加是角膜三叶和眼内球面像差，与角膜切口和植入晶状体有关。手术后的HOA变化在两种晶状体类型之间没有统计学差异。
