屈光学

Results: The refraction results of the Allegretto Wave Analyzer were very unstable. The spherical, cylinder diopter and the axis of the cylinder varied greatly. The refractive errors were large while the refractive errors were little by the subjective refraction examinations. During the wavefront examination, spots of the laser matrix were blurring, and the reproducibility was not good. Wavefront analyses showed that the Array pseudophakic eyes had relative large coma while the patients had no obvious symptoms.

研究结果：像差分析仪检测得的屈光度结果十分不稳定，球镜度、柱镜度、散光轴都变化很大，可重复性差，检测的屈光不正度数较大，而主觉验光时，患眼的屈光不正度数较低。5只眼的光学矩阵的测量点均非常模糊，且测量结果的可重复性较差，像差分析显示，Array人工晶状体有很大的第三阶彗差，但患者的自我感觉良好。

However, the operative site in optical center, the influence of the operator and the equipment, make almost all patients have the different degrees of ametropia and asthenopia and influence the recovery of the vision. These questions are very difficult to solve.

但手术部位多在光学中心，加之手术人员、设备等诸多因素的影响，几乎所有患者术后均存在不同程度的屈光不正而影响视力恢复，并引起不同程度的视疲劳，一直是眼科界难以解决的问题。

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。

Methods Retinoscopy and autorefractian were performed in 152 cycloplegic children eyes (76 people).

但人员需专门培训，且检查耗时较长。，自动验光仪是光学、电子和机械三方面组合起来进行屈光检查的新型仪器。

The "emmetropia" in geometrical optics and "the normal eye of refraction" in biomedicine were two different concepts, and should be differentiated.

几何光学的"正视眼"与生物医学角度的屈光"正常眼"是两个不同概念，应予以区分

Methods One hunderd amd ten human subjects (one hunderd and seventy-four eyes) were included in this research. Retinoscopy was made to measure refractive errors, corneal topographer was measured by corneal topography system, Tonometry was used to measure IOP, Ultrasonagraphy was applied to measure anterior chamber length, len thickness and vitreous length respectively, Laser interference biometer was used to measure axial length, Optical coherence tomography was used to measure retina thickness of fovea area. Based on spherical equivalent subjects were divided into four groups: emmetropia group (SE0.50D), low-myopia group (-0.50D≤SE3.00D), moderate myopia group (-3.00D≤SE6.00D) and high myopia group (SE≥-6.00D).

对近视患者及正视者110例（174只眼），主觉加检影验光行屈光检查，采用Humphrey测量角膜平均曲率，非接触式眼内压测量仪测量眼内压；A与B型超声诊断仪测量前房深度、晶状体厚度、玻璃体腔长度及眼轴长度；角膜测厚仪测量中央角膜厚度(CCT，centercornealthickness)；光学相干生物测量仪测量眼轴长度；光学相干断层扫描仪测量黄斑中心视网膜厚度；按等效球镜度数(SE， sphericalequivalent)不同分正视组(SE0.05D)、轻度近视组(-0.50D≤SE3.00D)、中度近视组(-3.00D≤SE＜-6.00D)、高度近视组SE≥-6.00D）。

Its axial resolving power depends on the coherency of light source,even 10μm,and the depth it can cut through isn't limited by the eye's transparent diopter medium.You can observe the structure of not only optic anterior ganglion but also posterior ganglion.It has a brilliant applied prospect in the diagnosis of entoptic disease especially retinal disease,随访观察 and evaluation of treatment result.

OCT是超声的光学模拟品，但其轴向分辨力取决于光源的相干特性，可达10um，且穿透深度几乎不受眼透明屈光介质的限制，可观察眼前节，又能显示眼后节的形态结构，在眼内疾病尤其是视网膜疾病的诊断，随访观察及治疗效果评价等方面具有良好的应用前景。
