BACKGROUND/AIM: This study aimed to evaluate astigmatism after cataract surgery by comparing the use of an intraoperative aberrometer combined with an image-guided system (VLynk) an image-guided system alone (Verion) in patients with significant lens opacity.
The main outcomes included the corrected distance visual acuity (CDVA), astigmatism, spherical equivalent (SE) status, and the predicting factors for reduced astigmatism in the two groups.
In this study, 73 patients were enrolled in the study group (VLynk); 76 individuals constituted the control group (Verion). Preoperative and postoperative CDVA between both groups were similar (all >0.05). The postoperative cylinder power (=0.002), postoperative SE (=0.004), and the difference between real SE and estimated SE (=0.001) were significantly lower in the VLynk group. Implantation of toric IOL was associated with less astigmatism in both groups (both <0.05). Longer axial length (=0.013) and higher central corneal power (=0.023) were correlated with greater astigmatism in the Verion group.
VLynk is correlated with better postoperative astigmatism control and predictability compared to Verion in patients with significant lens opacity.
背景/目的：本研究旨在通过比较术中像差仪联合图像引导系统（VLynk）与单纯图像引导系统（Verion）在晶状体明显混浊患者白内障手术后的散光情况，来评估术后散光。
主要观察指标包括两组患者的矫正远视力（CDVA）、散光、等效球镜度（SE）状态以及散光降低的预测因素。
本研究中，73例患者纳入研究组（VLynk）；76例构成对照组（Verion）。两组术前和术后的CDVA相似（均>0.05）。VLynk组的术后柱镜度（=0.002）、术后SE（=0.004）以及实际SE与预估SE之间的差值（=0.001）显著更低。两组中植入散光型人工晶状体均与较少的散光相关（均<0.05）。在Verion组中，眼轴长度更长（=0.013）和角膜中央屈光力更高（=0.023）与更大的散光相关。
在晶状体明显混浊的患者中，与Verion相比，VLynk与更好的术后散光控制及可预测性相关。
