散光

METHODS: A retrospective study of outcome of LASIK (Allegretto excimer laser system and Moria C-B microkaretome) for predominant myopic astigmatism (group A, 28 eyes) and normal myopic astigmatism (group B, 30 eyes).

分析LASIK技术（鹰视准分子激光系统和MORIA C－B微型角膜刀）治疗以散光为主眼(A组，28眼)和以近视为主眼(B组，30眼)的术后结果。

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。

Although subjects had a range of spherical ametropia, all had initial astigmatism of 1.0 DC or less.

尽管研究人群中有一定的屈光不正，所有病例都有1.0DC 以内的散光。

Objective To assess the importance of overrefraction in the soft contact lens fitting of patients with higher ametropia or moderate to higher astigmatism.

The design of four-mirror anastigmat was analyzed, then a system with effective focal length of 1 200 mm and field of view of 0.8°×0.8° was designed , total length and f-number are 300 mm and F/6,respectively.The system has advantages of long focal length, relative short physical size and excellent ability in restraining stray lights.

分析了离轴四反的设计步骤，设计了一个焦距为1 200 mm，视场为0.8°×0.8°，相对孔径为F/6的光学系统，系统总长只有300 mm，并达到很好的光学性能，具有长焦距、小尺寸、良好的杂散光抑制能力等特点。

In order to meet the requirements of high space resolution, high spectral resolution, high time resolution, small volume and light weight for the remote sensing of pilotless planes, the off-axis three-mirror anastigmatic optical system is adopted.

Compared with previous reports of similarly aged Singapore Chinese adults, the prevalence of myopia, astigmatism, and anisometropia was lower, whereas the prevalence of hyperopia was similar.

与前期报道的相似年龄的新加坡中国成年人相比，马来人的近视、散光和屈光参差的患病率要低，但远视的患病率相似。

Methods The retrospective study involved 196 patients（300 eyes） with myopia anisometropia and mixed astigmatism who received LASIK treatment from August in 2002 to August in 2007 in our department.
