To explore the effect of image-guided systems in phacoemulsification with intraocular lens (IOL) implantation.
We searched Pubmed, Embase and China National Knowledge Infrastructure (inception to January 20, 2021). Two researchers extracted data and assessed paper quality independently. Uncorrected distance visual acuity (UDVA) before and after surgery, best corrected visual acuity (BCVA) before and after surgery, preoperative cylinder, postoperative residual refractive cylinder, postoperative corneal cylinder, IOL misalignment, and intraocular pressure (IOP) were compared.
We included 14 studies with 885 cataract eyes. All data were performed using Review Manager 5.3 (RevMan 5.3) (https://revman.cochrane.org/). Cases of all preoperative outcomes showed no significant difference between image-guided group and manual group. There was no significant difference in postoperative UDVA (Standard mean difference (SMD: -0.11, 95% CI: -0.32 to 0.11, = 59%, = 0.33)), BCVA (SMD: 0.03, 95% CI: -0.12 to 0.18, = 36%, = 0.72), corneal cylinder (Weighted mean difference WMD: 0.13, 95% CI: -0.06 to -0.32, = 0%, = 0.17), IOP (WMD: -0.37, 95% CI: -1.36 to -0.62, = 9%, = 0.46) between two groups. There was less residual refractive cylinder in image-guided group than in manual group (WMD: -0.20, 95% CI: -0.26 to -0.14, = 59%, ＜0.00001). It is more accurate in IOL alignment when combined with image-guided systems (WMD: -1.20, 95% CI: -1.43 to -0.96, = 14%, < 0.00001).
Image-guided systems can improve the effect in phacoemulsification with intraocular lens (IOL) implantation.
探讨图像引导系统在白内障超声乳化人工晶状体植入术中的作用。
检索了PubMed、Embase和中国知网（建库至2021年1月20日）。两名研究人员独立提取数据并评估论文质量。比较手术前后的未矫正远视力（UDVA）、最佳矫正视力（BCVA）、术前散光、术后残余屈光性散光、术后角膜散光、人工晶状体偏心和眼压（IOP）。
我们纳入了14项研究，共885只白内障患眼。所有数据均使用Review Manager 5.3（RevMan 5.3）（https://revman.cochrane.org/）进行分析。所有术前指标在图像引导组和手动组之间均无显著差异。两组术后UDVA（标准均差（SMD）：-0.11，95%可信区间：-0.32至0.11，I² = 59%，P = 0.33）、BCVA（SMD：0.03，95%可信区间：-0.12至0.18，I² = 36%，P = 0.72）、角膜散光（加权均差（WMD）：0.13，95%可信区间：-0.06至0.32，I² = 0%，P = 0.17）、IOP（WMD：-0.37，95%可信区间：-1.36至0.62，I² = 9%，P = 0.46）均无显著差异。图像引导组的残余屈光性散光少于手动组（WMD：-0.20，95%可信区间：-0.26至-0.14，I² = 59%，P＜0.00001）。联合图像引导系统时人工晶状体定位更准确（WMD：-1.20，95%可信区间：-1.43至-0.96，I² = 14%，P＜0.00001）。
图像引导系统可提高白内障超声乳化人工晶状体植入术的效果。
