Automated refraction with the Canon RK-1 Autoref keratometer was evaluated in 110 eyes (110 patients) six to eight weeks after they had undergone extracapsular cataract extraction with posterior chamber intraocular lens implantation and achieved a best corrected visual acuity of at least 6/12. Autorefraction readings were obtained in 100 (91%) of these eyes. The agreement between autorefraction and clinical refraction data was 98% for spherical equivalence less than 0.51 dioptres (D), 95% for sphere power less than 0.51D, 94% for cylinder power less than 0.51D, and 85% for cylinder axis less than 11 degrees. Autorefraction can provide acceptably accurate postoperative refraction values in pseudophakic eyes.
对110例患者的110只眼睛在接受白内障囊外摘除联合后房型人工晶状体植入术后六至八周且最佳矫正视力至少达到6/12时，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100只眼睛（91%）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98%；球镜度数小于0.51D时为95%；柱镜度数小于0.51D时为94%；柱镜轴小于11度时为85%。自动验光可为人工晶状体眼提供可接受的准确术后验光值。
