Basic research for wavefront-guided refractive surgery : The evaluation of effects of aberrations and scatterings on the optical function of the eye

作为术后并发症的原因之一，一过性角膜扩张与明显的眼压升高有关。单眼三视是中年轻度核性白内障和高度近视患者的报告。波前分析表明，核性白内障晶状体的三叶形和球面像差共同增加，组织工程化上皮细胞片移植可有效预防准分子激光角膜切削术后角膜混浊的发生，Hartmann-Shack像差仪测量的泪液破裂时间可作为泪液破裂的实用指标。

As one of the cause of post-operative complications, the mechanism of transient keratectasia in association with a marked intraocular pressure (IOP) elevation was shown.Monocular triplopia was reported by middle-aged patients with mild nuclear cataract and high myopia. Wavefront analyses suggested that the triple configuration was caused by the combined increase of the trefoil and spherical aberration in lenses with nuclear cataract.The transplantation of tissue-engineered epithelial cell sheets can successfully prevent the development of corneal haze after excimer laser keratectomy.The tear break-up time measured by Hartmann-Shack aberrometer may be used as a practical measure of tear break-up.
