復(fù)性遠(yuǎn)視散光 - 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
采用超環(huán)面( toroidalsurface )建立起規(guī)則散光下的角膜曲面模型方程;定量研究了手術(shù)光學(xué)區(qū)屈光不正兩種通用的矯正模型,一種模型適用于單純近視、復(fù)性近視散光、單純近視散光的矯正,另一種模型適用于單純遠(yuǎn)視、復(fù)性遠(yuǎn)視散光、單純遠(yuǎn)視散光的矯正;另外,作為影響手術(shù)效果的重要因素,提出了一種用于光學(xué)區(qū)直徑和過渡區(qū)寬度均可調(diào)節(jié)時(shí)過渡區(qū)角膜切削量的計(jì)算模型。
