Abstract：ObjectiveWe planned to review refractive error correction techniques and methods implemented in foreign military aviator by using meta-analysis, and to adapt them as references for study.MethodRetrieving literature of fifty-six papers, in this field from medical bibliographic databases and foreign military official websites,scientific-technical reports and network information were cited. The summary data of statistical analysis of the original information was achieved by using of comprehensive meta-analysis.ResultsThe foreign military vision requirement has been gradually broadened. For example, the USAF’s corrected visual acuity was 20/20, while uncorrected visual acuity was broadened to 20/70. The ratio of wearing corrective lenses rises gradually, from 17% to 41% in pilots. Corneal refractive surgeries (CRS), such as PRK and LASIK, have become the main methods of refractive error correction since 2000. Evaluation for aviation environment at +9 Gz and 35 000 ft after CRS was performed, no obvious effect showed on visual acuity.Conclusion CRS was efficacious and safe option for refractive error correction. It can effectively improve ametropia of foreign military pilots for its rather high postoperative satisfaction, and the aviators can quickly restore to their operational capability and return to flight status.
