Automated refraction with the Canon RK-1 Autoref keratometer was evaluated in 85 eyes of 85 patients with an anterior chamber intraocular lens implant and a best corrected visual acuity of at least 6/12. Autorefraction readings were obtained in 80 (94%) of these eyes. The agreement between autorefraction and clinical refraction data was 89% for spherical equivalence less than 0.51 dioptres (D), 91% for sphere power less than 0.51 D, 82% for cylinder power less than 0.51 D, and 91% for cylinder axis less than 11 degrees. Autorefraction provides acceptably accurate postoperative refraction values in anterior chamber pseudophakia.
对85例植入前房型人工晶状体且最佳矫正视力至少为6/12的患者的85只眼，使用佳能RK - 1自动验光角膜曲率计进行自动验光评估。其中80只眼（94%）获得了自动验光读数。当球镜等效度小于0.51屈光度（D）时，自动验光与临床验光数据的一致性为89%；球镜度数小于0.51 D时，一致性为91%；柱镜度数小于0.51 D时，一致性为82%；柱镜轴小于11度时，一致性为91%。自动验光可为前房型人工晶状体术后提供可接受的准确验光值。
