屈光度

Paired Samples T test revealed that both the LT and VL decreased (P.01), the AD increased (P.01) after cycloplegia regardless of their refractive state. The AL increased for hyperopic eyes (P.05) and decreased for myopic eyes (P.01) after cycloplegia. For hyperopic eyes, the major keratometer K1 increased (P.05) while for myopic eyes, the major keratometer K1(P.05) and minor keratometer K2 (P.01) decreased after cycloplegia. The mean corneal power of zones 5 mm (MD5) and 7 mm (MD7) decreased with myopic eyes decreased dramatically (P.01). The mean refractive power of the lower half vertical meridian is greater than that of upper half; and the mean refractive power of the lateral half of the horizontal is greater than that of the medial half.

结果：不论远视眼、正视眼还是近视眼在睫状肌麻痹后前房加深（P.01），晶状体变薄（P.01），玻璃体腔径缩短（P.01）；但远视眼睫状肌麻痹后眼轴增长（P.05），近视眼眼轴缩短（P.01）；远视眼睫状肌麻痹后角膜曲率K1增加（P.05），近视眼睫状肌麻痹后除K1降低外（P.05），K2以及以角膜中心点为中心，直径为5mm、7mm的环平均角膜屈光度（MD5、MD7）均降低（P.01）；此外，垂直径线上方的平均角膜屈光度小于下方的平均角膜屈光度而水平径线鼻侧的平均角膜屈光度小于颞侧的平均角膜屈光度（P.01）。

Methods Diopter were followed up to study during one year in 665 children aged 6～14 years.

对 6～ 14岁 6 6 5名学生眼屈光度进行一年追踪检测，应用远视屈光度下降值研制学生近视眼屈光阈值。

Objectives: To study the relation between eyesight and diopter of students' myopia,and then provide quickly detect methods for evaluating prevention and cure effect of adolescents'myopia.

评价青少年近视眼的防治效果，裸眼视力是目前最常用的变量指标，而屈光度是很有探讨价值的客观指标，一般而言随着视力的变化屈光度会发生相应的改变。

A dioptre is 1 divided by the focal length of the lens in centimetres. So a 1-dioptre lens has a focal length of 1m; a 2-dioptre lens has a focal length of 50cm; a 5D lens has a focal length of 20cm.

一屈光度是1除以该镜头焦距在厘米，所以一屈光度镜头焦距一米； 2屈光度镜头焦距50厘米； 1日5日镜头焦距二○厘米）。

The differences of CCT between the Uygur myopia patients and the han nationality myopia patients and the relationship between corneal curvature, intraocular pressure value, dioptre and CCT in the Uygur nationality were analyzed.

对屈光中心就诊近视患者汉族137例274眼及维吾尔族患者115例230眼测量其角膜中央厚度、眼压、屈光度及角膜曲率，分析维吾尔族与汉族CCT差异性及维吾尔族CCT与角膜曲率、眼压值及屈光度关系。结果：维吾尔族CCT(514.94±31.94μm)与汉族CCT(514.86±29.50μm)无显著性差异(t=0.029，P=0.977)。

Methods The patients were divided into three groups according to the dioptre:group of superior high myopic eye（-6.0～9.5D）,group of over high myopic eye（-10.0～-14.5D）and group of excessively high myopic eye（≥-15.0D）.

将高度近视眼按不同屈光度分为3组。屈光度-6.0～-9.5D为高高度近视眼组；屈光度-10.0D～-14.5D为超高度近视眼组；屈光度≥-15.0D为极高度近视眼组。

Objective:Since some limitaions of SRK Ⅱ formula,the dual cubic curved regressive formula was designed. methods:By means of computer,statistical analysis and regressive treatment of kerato diopter,axial length and emmetropic IOL diopter of 415 pseudophakia was done.

针对目前临床上常用的SRKⅡ公式在计算人工晶体屈光度时的局限性，对415只后房型人工晶体眼的角膜屈光力、眼轴长度和正视化人工晶体屈光度进行回归分析后，设计出一种不同于传统的线性回归公式的曲线回归公式——二元三次计算公式。

The intravitreous injection of rhIGF-2 has no effect on the degree of myopia and axial length of the non-FD guinea pig, while it can induce significant increases in the degree of myopia and axial length in the FDM guinea pig and the effects are concentration dependent.

rhIGF-2玻璃体腔注射对豚鼠非遮盖眼的屈光度和眼轴长度无影响，但可使形觉剥夺眼近视屈光度增加，眼轴延长，其效应呈浓度依赖性。rhIGF-2可下调豚鼠眼视网膜－脉络膜内源性IGF-2的表达，效应呈浓度依赖性。

METHODS:The CCT and ocular axial length were measured by ultrasonic,IOP by non-contact tonometer,refraction by keratometer in 252 eyes of 126 cases with high myopias,respectively.

根据近视屈光度不同分为4组，即按等效球镜分为：1组-6.00D≤屈光度7.00D，72眼；2组-7.00D≤屈光度8.00D，80眼；3组-8.00D≤屈光度9.00D，48眼；4组≥-9.00D，52眼。

The pupil diameter of different diopters changes greatly under different rays, and it is a very important parameter to measure the pupil diameter in different diopter under different rays before the refractive surgery.

不同屈光度在不同光线下瞳孔直径有很大的变化；不同屈光度在不同光线下的瞳孔直径是屈光手术前评估的一个重要参数。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
