关注屈光性白内障手术时代的精准眼球生物测量

Pay attention to the precise ocular biometry in the era of refractive cataract surgery

近年来,白内障的手术治疗从复明性手术进入屈光性手术时代,对术前精准而全面的眼球生物测量提出了更高的要求。精准眼球生物测量,既包括眼轴长度、角膜曲率、前房深度、晶状体厚度及角膜直径等眼球结构参数的测量,还纳入了Kappa角、Alpha角及波前像差等视光学参数。了解每个参数的测量方法和临床应用,合理的选择检查设备,正确的判读检查结果,是每位屈光性白内障手术医师应掌握的内容。

In recent years,the cataract surgery for restoring vision has been developped into the refractive cataract surgery(RCS).The era of RCS has been coming,which causing to require more accurate and comprehensive preoperative ocular biometry.Accurate ocular biometry does not only include the measurement of the structural parameters of the eyeball,e.g.axial length,corneal curvature,anterior chamber depth,lens thickness,and corneal diameter,but also some vision optics parameters,e.g.Kappa angle,Alpha angle,wavefront aberration,etc.It is obligatory upon refractive cataract surgeons to understand the measurement method and clinical application of each parameter,select the examination equipment reasonably,and interprete the results correctly.
