1·Results The visual axis were clear and IOLs in position in all operation eyes.

结果术后全部术眼视轴透明，人工晶状体在位。

2·Methods PCCC was performed on 30 eyes of 18 infants with congenital cataract Results The eyes achieved a clear visual axis.

方法对18例（30眼）幼儿先天性白内障采用一期后囊环形撕囊。结果术后术眼均达到视轴区透明。

3·This paper USES a method of stable platform to achieve visual axis stability, the vibrating on visual axis brought by mobile carrier.

针对载体运动会给视轴带来影响，提出利用稳定平台实现视轴的稳定。

4·The length of the visual axis was the distance from the corneal vertex to the macular fovea, and it was also measured by A-mode ultrasound in sitting position with different ultrasonic velocity.

以角膜顶点至黄斑中心凹距离作为视轴长度，此连线上测量硅油后间隙的厚度。

5·Though central green axis is important to produce visual effects, form spatial pattern, and provide ecological benefits in the central area of a city, it still has plenty of problems.

虽然中心绿轴对于城市中心区视觉效果、空间结构、生态效益等方面都有重要的作用，但是仍存在众多的问题。

6·Results: the result showed that all the eye achieved a clear axis and better visual acuity.

结果：术后全部术眼均获得视轴透明区。矫正视力均有不同程度提高。
