摘　　要：目的比较ORBSCANⅡ和角膜曲率计测量角膜曲率的临床应用效果。方法应用ORBSCANⅡ和角膜曲率计分别测量110眼角膜曲率,A超测量眼轴长度,并分别代入THEORETIC/T或REGRSSIONⅡ公式,计算所需人工晶状体(IOL)度数。结果角膜曲率及眼轴长度和IOL度数之差异均无统计学意义(P>0.05)。结论应用ORBSCANⅡ测量角膜曲率和角膜曲率计有很好的一致性,均能较好地为开展白内障超声乳化人工晶状体植入术服务。Objective To compare clinieal effeets of ORBSCAN Ⅱ with keratometer in determining corneal curvatures. Methods To get corneal curvatures among 110 eyes with the equipment of ORBSCAN Ⅱ and keratometer, and get the ocular axis length with A-scan uhrasongraphy and then apply them to the THEOREFIC/T Ⅱ formula respectively,and the power of IOL is available accordingly. Results There are no statistical differeee between the corneal curvatures,ocular axis length and IOL power（ P 〉 0.05）. Conclusion A coherent result can be got with ORBSCAN Ⅱ and keratometer to count the corneal curvatures, and both lead to good service of phacoemulsifieation and intraueular lens implantation.
