1·Have a disease or abnormality of the cornea, such as keratoconus or corneal edema.

角膜有异常或病变，比如圆锥角膜或角膜水肿。

2·Two types of keratoconus after PKP have remarkable divergence of post-operative corneal topography(P<0.01).

圆锥角膜术后两种类型角膜地形图参数差异有显著意义（P<0.01）。

3·Objective Appraise the important effect of the corneal topographic analysis in the early keratoconus diagnosis.

目的评价角膜地形图分析在圆锥角膜早期诊断中的重要作用。

4·Keratoconus is a deterioration of the structure of the cornea with gradual bulging from the normal shape to a cone shape.

圆锥角膜是一种角膜的结构退化，病发时患者角膜由正常情况下的圆形逐渐鼓胀成圆锥形。

5·Our present study was to investigate the corneal posterior surface topography in different clinical stages of keratoconus.

目的分析各期圆锥角膜后表面的形态特点，为完善圆锥角膜形态特点的描述提供参考。

6·There is also a relatively rare condition called keratoconus where the cornea becomes progressively thinner and cone shaped.

当然，在极少数情况下，角膜会逐渐地变地很薄，形成圆锥形角膜。

7·Conclusions:Iatrogenic keratoconus, high myopia and high astigmatism are the major cause of vision lowering after RK, PRK LASIK.

结论：RK、PRK、LASIK术后视力低下的主要原因是医源性圆锥角膜和高度近视、高度散光。

8·ConclusionIncreasing EGF accelerates DNA synthesis of epithelial cells and stromal cells in keratoconus to cause tissue healing.

结论圆锥角膜组织中egf水平增高，促进上皮细胞和基质细胞的DNA合成，从而使组织愈合。

9·Objective to evaluate the visual quality in keratoconus eyes corrected by rigid gas-permeable contact lens (RGPCL) and spectacles.

目的评价透气性硬性接触镜(RGPCL)和框架眼镜矫正圆锥角膜的视觉质量差异。

10·Objective to observe the expression of collagen type I and II in normal cornea and keratoconus, and discuss the effects on the keratoconus.

目的观察正常人及圆锥角膜中i、II型的表达，探讨胶原i、II型在圆锥角膜病变中的变化。

圆锥角膜

1·Have a disease or abnormality of the cornea, such as keratoconus or corneal edema.
