curvature of cornea 中文意思是什麼

curvature of cornea 解釋
角膜球面變曲度
  • curvature : n. 1. 彎曲（部分）。2. 【數學】曲率，曲度。
  • of : OF ＝Old French 古法語。
  • cornea : n. 【解剖學】角膜。 cornea transplant 【醫學】角膜移植。adj. -l
  1. They accommodate by greatly changing the curvature of the cornea.

    它們由大大地改變角膜曲率的方法來調節。
  2. Based on the diopter status of myopia and hypermetropia, the paper presented the principle of excimer laser refractive surgery, the change of impacting cornea curvature on the cornea diopter. in this chapter, we also discussed excimer laser - corneal tissue interactions and photoablation. determine the relationship between the fluence of arf excimer laser and the cornea ablation rate, attain the relationship between the energy density and the ablation depth

    研究了激光與生物組織相互作用、光蝕作用及準分子激光消融角膜的機理；首次定量研究193nm準分子激光高斯光束的切削量與能量密度的關系，計算單個激光脈沖角膜切削量；發現了角膜曲率對切削效果的影響，首次提出了角膜曲率半徑、切削位置與切削深度的關系；首次定量確定了激光光斑參數及其排列方式對術后角膜表面粗糙度的影響，為更精確實現角膜切削和提高切削后角膜表面光潔度、減少手術后角膜渾濁及角膜表面術后不規則提供了理論依據。
  3. There are many different kinds of refractive surgery, but the principle is the same - changing the curvature of the cornea or lens to place the focus sharply back onto the retina

    激光矯視種類繁多，然而，其原則如一，即改變角膜或晶體弧度，以令焦點明確地重落在視網膜上。
  4. Astigmatism is caused by differences in the curvature of the cornea in different meridians, distorts the light rays entering the eye and prevents them from focusing sharply. astigmatism can occur with short - sightedness and long - sightedness

    如果角膜稍有弧度不一，某一面弧度較彎，而另一方較扁平，光線便不能準確地聚焦在視網膜上，這種情況便稱為散光。
