正视眼的

Objective To investigate the effect of lower degree convex lens on preventing myopia of primary school students.

目的 探讨低度凸透镜预防小学生视近的效果。方法采用随机分组的方法将男女各半的 16 0 0名小学三年级正视眼学生分为实验组和对照组。

Objective:To study the corneal topography of children who are emmetropia and that of myopia.

目的：研究儿童正视眼与儿童近视眼的角膜地形图特征并进行比较。

The dioptric equivalent of the near point of emmetropiais the amplitude of accommodation.

1正视眼近点的等效焦度称为调节幅度。

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。

Methods:115 emmetropia eyes and 115 myopia eyes were measured by using a computerized corneal topography.

应用计算机辅助的角膜地形图检测分析了115只儿童正视眼和115只儿童轻中度近视眼。

With normal vision were studied. The result showed: 504 eyes (77. 54%) suffered from hyperopia, 66 (10.15%) from myopia, 2(0.31%)from astigmatism and 78(12. 00%) were emmetropia. Among 325 youths, 172 (52.92%) had esophoria (including esophoria-hy- perphoria), 126 (38.7%)exophoria (including exophoria-hyperphoria), 13(4.00%) hyperphoria and 14(4.31%)had orthophoria. No significant...

结果显示，远视者为504眼(77.54％)，近视者66眼(10.15％)，混合散光者2眼(0.31％)，正视者78眼(12.00％)，325人中，内隐斜者为126人(38.77％)，上隐斜者13人(4.00％)，正位者14名人(4.31％)；经用行x列表的x~2检验法分析，屈光不正的类型与斜视的种类之间没有显著联系。

Methods: Forty of cases 77 emmetropic and ametropic eyes were measured with an aberrometer based on Tscherning's principle with the pupils dilated. The Zernike coefficients and root mean square values of wavefront aberrations up to the 6th order were recorded and statistically analyzed.

40人77只正视眼及屈光不正眼，散瞳后用基于Tscherning原理的波阵面像差仪进行测量，记录高达6阶的波阵面像差Zernike系数和均方根值，并进行统计学分析。

Objective To study the relationship between surgical prognosis of retinal detachment in emmetropic or myopic eyes and vitreous changes.

目的 研究正视眼视网膜脱离(retinal detachment，RD)患者的手术预后及其与玻璃体改变的关系。

It is possible that the vitreous characteristics in emmetropic eyes with RD have relationship to the occurrence and development of PVR that has the influence on the prognosis to some extent.

这种正视眼RD玻璃体的特殊病理过程，更易导致PVR的发生、发展，从而影响手术预后

Result The time of near accommodation are 376ms and 371ms, and far accommodation 477ms and 488ms in emmetropes and early-onset myopes respectively.

结果 正视眼与早发性近视眼的远调节反应时间(477、488ms)比近调节反应时间(376、371ms)长(P.01)。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
