摘要

目的分析短眼轴两侧平均角膜曲率与人工晶状体(IOL)差异的关系。方法随机抽取500例正常成人白内障患者的角膜曲率进行前瞻性研究。在角膜曲率相同的情况下，获得角膜曲率177例;平均177例角膜曲率，平均角膜曲率范围为40.125 ~ 48.375 d。在平均角膜曲率范围内，根据计算出的临界眼轴长度(21.97 ~ 22.02mm)，得出人工晶状体的差值。分析人工晶状体差值与平均角膜曲率的相关性。结果人工晶状体差值与短轴临界轴平均角膜曲率呈负相关(r=-0.968, P=0.000)。结论角膜正常的成人白内障患者，随着角膜平均曲率的增大，人工晶状体数的差异逐渐减小。关键词:角膜曲率;短轴;人工晶状体;白内障

Effect of corneal curvature on the difference of intraocular lens in short eye axis

Objective To analyze the relationship between the average corneal curvature and the difference of intraocular lens (IOL)on both sides of the short eye axis. Methods Prospective study of corneal curvature on randomly collected 500 corneas of normal adult cataract patients. With the same corneal curvature, 177 cases of corneal curvature were obtained; the average of 177 cases of corneal curvature was obtained, the range of the average corneal curvature was 40.125-48.375D. In the range of average corneal curvature, according to the calculated critical axial length (21.97-22.02mm), the difference of IOL was obtained. The correlation on intraocular lens of difference and average corneal curvature were analyzed. Results There was a negative correlation between the difference of intraocular lens and the average corneal curvature in critical axial of short axis r=-0.968, P=0.000. Conclusions In normal adult cataract patients with normal corneal, the difference of intraocular lens number gradually becomes smaller with the increase of average corneal curvature. Key words: Corneal curvature; Short axis; Intraocular lens; Cataract
