Methods IOL Master and ultrasound biometry were performed in 154 eyes to measure AL and ACD. SRK II, Haigis, Holladay, Hoffer Q and SRK-T formulas were used for IOLs power calculation. 3 months after surgery, patients were checked their refractive error.

121例（154眼）老年性白内障，术前分别应用IOL Master和眼科传统设备两种方法测量眼部参数并计算所需人工晶状体的屈光度，术后检查术眼屈光误差。

The axial length, refraction power of cornea（K1 and K2）and anterior chamber depthwere determined by optic coherence biometryafter cycloplegia.

3 12岁近视儿童79例140眼经门诊睫状肌麻痹后检影验光，采用光学相干生物测量仪测量其眼轴长度、角膜屈光力（K1、K2）、前房深度，计算眼轴长度与角膜曲率的比值AL/CR，对测量值进行统计分析。

The results of corneal topography, that of keratometer and cycloplegic retinoscopy in measuring astigmatism before refractive surgery were compared, and the measuring results of corneal topography and that of keratometer for 72 eyes after photorefractive keratectomy and 95 eyes after laser in situ keratomileusis were also compared.

采用计算机辅助的角膜地形图、角膜曲率计及散瞳验光三种测量散光的方法，对屈光不正患者360只眼进行检查，同时对准分子激光角膜切削术（photorefractive keratectomy，PRK）后72只眼和准分子激光原位角膜磨镶术（excimer laser in situ keratomileusis，LASIK）后95只眼的角膜散光用角膜地形图和角膜曲率计进行测量并比较。

For five anisometropic amblyopes and five normal controls, contrast sensitivities in both grating motion direction discrimination and moving grating detection were measured with the same moving sinewave stimuli over a wide range of spatial and temporal frequencies.

我们采用心理物理学方法研究了屈光参差性弱视患者对正弦运动光栅识别能力的损伤机制，测量了在一定时间空间频率下五名屈光参差性成人弱视患者和五名正常对照被试运动方向辨别和运动光栅检测的对比敏感度。

Abstract］ Objective To evaluate the detection rate, accuracy and factors influencing the measurement of axial length in cataractous eyes using the IOL Master version 5.0 with a composite signal analysis system.

在白内障超声乳化吸除联合人工晶状体植入术中，术前准确测量眼轴长度并计算植入的人工晶状体度数是非常关键的步骤，目前，术后的屈光误差主要来自于由术前眼轴测量误差引起的人工晶状体度数偏差[1-2]。

Both of the manual keratometry and average simulated keratometry were used to measure anterior radius of cornea only, overestimation of corneal power by them could be expected after refractive surgery owing to negligence of posterior radius of cornea.

由於传统平约K值与拟传统平均K值均只测量角膜的前弧度，故於准分子雷射屈光手术后，若仅以这些方法量得角膜的屈光能力，将会产生数值过大现象。

Methods:Based on the measured diopters,278 patients (538 eyes) that were to receive PRK operation were divded into 4 groups:mild,medium,high,and superhigh myopia,respectively.

目的：通过测量近视眼的角膜屈光力、眼轴和角膜中央厚度，分析角膜屈光力、眼轴和角膜中央厚度与近视程度的关系。

Methods Ninety-five subjects (50 myopes, 20 emmetropes, 25 hyperopes) aged 6~15 years, participated. The accommodative lag and amplitude of accommodation were assessed with their refractive errors corrected. The accommodative lags were assessed using MEM dynamic retinoscopy at 40 cm reading distance.

应用动态检影法和移近法分别测量50例发病1~2年的学龄期儿童和青少年近视患儿调节滞后和调节幅度；同样方法测量20例正视眼儿童和25例远视屈光不正患儿；检测其主导眼和非主导眼。
