Purpose

To evaluate the astigmatism after cataract surgery between the use of intraoperative aberrometer plus image-guided system (VLynk) and image-guided system (Verion) alone in patients with significant lens opacity. 

Setting

First-Brightness Eye Clinic,Taichung, Taiwan

Methods

A retrospective cohort study was conducted. A total of 73 patients with optical-disturbance cataract and received VLynk system management were enrolled in the study group, while another 76 individuals with Verion system approach constituted the control group. The main outcomes included the best-corrected visual acuity (BCVA), astigmatism, spherical equivalent (SE) status and the predicting factor for less astigmatism in the two groups. Generalized estimated equation (GEE) was used to produce the adjusted odds ratio (aOR) and corresponded 95% confidence interval (CI). 

Results

The preoperative and postoperative BCVA between the VLynk and Verion groups were similar (all P > 0.05). The preoperative cylinder power, preoperative SE and estimated SE were statistically insignificant between both groups (all P > 0.05). Postoperative cylinder power (-0.28 ± 0.15 vs -0.96 ± 0.88), the postoperative SE (-0.18 ± 0.41 vs -0.57 ± 0.74) and difference between real SE and estimated SE (-0.03 ± 0.21 vs -0.41 ± 0.58) were significantly lower in the VLynk group. Implantation of toric IOL was significantly associated with lesser 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 higher astigmatism in the Verion group.  

Conclusions

The application of VLynk system is correlated to better postoperative astigmatism control and predictability compared to the use of Verion system in patients with significant lens opacity.
