Abstract

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) versus an image-guided system alone (Verion) in patients with significant lens opacity.

Patients and methods: 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.

Results: 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 p>0.05). The postoperative cylinder power (p=0.002), postoperative SE (p=0.004), and the difference between real SE and estimated SE (p=0.001) were significantly lower in the VLynk group. Implantation of toric IOL was associated with less astigmatism in both groups (both p<0.05). Longer axial length (p=0.013) and higher central corneal power (p=0.023) were correlated with greater astigmatism in the Verion group.

Conclusion: VLynk is correlated with better postoperative astigmatism control and predictability compared to Verion in patients with significant lens opacity.
