  4. Corneal surfaces in eyes with regular astigmatism are thought to be toroidal surfaces. based on mathematical models for corneal surfaces before and after treatment, a corneal ablation model is given for such refractive errors as spherical myopia, compound myopic astigmatism, and simple myopic astigmatism. a similar corneal ablation model is also given for such refractive errors as hyperopia, compound hyperopic astigmatism, and simple hyperopic astigmatism

    採用超環面（ toroidalsurface ）建立起規則散光下的角膜曲面模型方程;定量研究了手術光學區屈光不正兩種通用的矯正模型，一種模型適用於單純近視、復性近視散光、單純近視散光的矯正，另一種模型適用於單純遠視、復性遠視散光、單純遠視散光的矯正;另外，作為影響手術效果的重要因素，提出了一種用於光學區直徑和過渡區寬度均可調節時過渡區角膜切削量的計算模型。
  5. The relation of total astigmatism and corneal astigmatism in cycloplegic children eyes

    小兒靜態總合散光與角膜散光的關系

  9. We had found that the error of predicted refraction may present with cases of large deviation between the preoperative and the postoperative keratometric measurement, or high corneal astigmatism

    我們發覺手術前後角膜曲度變化量較大或術后散光較高的病患群中，其預測的人工水晶體度數亦有較大的誤差。
  10. Using the new excimer laser photorefractive keratectomy ( prk ), the molecular bond of the corneal stroma is broken to allow recofiguration of the cornealsurface. this photo - ablation effect can treat severe myopia, astigmatism, and a variety of corneal diseases using photo - therapeutic keratectomy ( ptk ). the safety, predictability, and long - term stability are well established in major western medical facilities
