Abstract：
OBJECTIVE: To systematically review the published manuscripts on stereopsis after corneal refractive surgery.
METHODS: The Web of Science, PubMed, Scopus, ProQuest, Clinical Key, Embase, and Cochrane Library were searched for relevant articles published until August 2020. The fixed- or random-effects models were used to estimate the Weighted mean difference (WMD) or Relative risk (RR) and 95% Confidence interval (CI) for postoperative stereopsis changes and incidence when applicable. Meta-regression was conducted for adjusting the effects of potential confounders.
RESULTS: Seven studies (1266 eyes) in adults and ten studies in pediatrics (259 eyes) were included. In adults, stereopsis improved significantly compared to the preoperative state (WMD = - 27.4, 95% CI = - 40.0, - 14.7; I2 = 97.8%; P < 0.001). In pediatrics, proportion of patients with stereoacuity postoperatively was 2.18 times compared to preoperative evaluation. (RR = 2.18, 95% CI = 1.2, 3.9; I2 = 68.6%, P < 0.001).
CONCLUSIONS: Stereopsis improves after corneal refractive surgery in adults and pediatrics.

摘要：
目的：系统回顾已发表的关于角膜屈光手术后立体视的手稿。
方法：WebofScience，PubMed,Scopus,ProQuest,临床关键,Embase,搜索了Cochrane图书馆直到2020年8月发表的相关文章。固定或随机效应模型用于估计术后立体视觉变化和发生率的加权平均差（WMD）或相对风险（RR）和95％置信区间（CI）。进行元回归以调整潜在混杂因素的影响。
结果：纳入了7项成人研究（1266只眼）和10项儿科研究（259只眼）。在成年人中,与术前状态相比，立体视明显改善（WMD=-27.4，95％CI=-40.0，-14.7；I2=97.8％；P<0.001）。在儿科，与术前评估相比，术后立体视力患者的比例为2.18倍。（RR=2.18，95%CI=1.2，3.9；I2=68.6%，P<0.001)。
结论：成人和儿科角膜屈光手术后立体视改善。
