查询词典 cornea

The donor cornea is measured and cut to fit a circular opening, which is made in the central part of the patient's cornea; the patient's cornea is lifted bloodlessly off -- there are no blood vessels in the cornea -- and the new cornea is sewn in with thread that is finer than a human hair.

After 1-month treatment, his best corrected visual acuity improved from 0.05 initially to 1.2, and the corneal thickness was not different between eyes. Nevertheless, at the injured sites, cornea was apparently thicker and corneal endothelial densities were lower than those in the fellow eye. This cornea might decompensate after any other ocular trauma or intraocular surgery.

经过一个月的治疗后，视力、眼压、中央角膜厚度、角膜上皮、前房、视网膜等皆恢復正常，但角膜內皮细胞密度明显减少，受伤部位的角膜亦明显较厚，日后恐有角膜失偿的危险，而这种情况无法藉测量中央角膜厚度显示出来。

Abstract］ objective to discuss the prevention and treatment of cornea eyewinker.methods to take different measure to eliminate cornea eyewinker.results in 118 cases,the number of complete elimination was 98（83%）,another cases were eliminated completely when they attend the clinic.conclusion cornea eyewinker must take early treatment to remove,tle method is effective with much less side-effect.

目的 探讨角膜异物的预防和治疗。方法采取不同的治疗措施剔除异物。结果 118例中一次取净98例（83%），其余复诊时取净。结论角膜异物应尽早采取治疗措施取除异物，其疗效可靠，不良反应更少。

Methods A lamellar flap was produced in the rabbit cornea with a microkeratome. The flap interface in whole corneas and corneal beds were soaked in the rAAV –EGFP solution for 10 min, BSS solution was applied in the control group. The corneas were harvested at day 1, 3, 14, and 21 after application for the structure analysis of cornea by HE staining. Expression of the transferred gene was monitored by fluorescence stereoscope and laser confocal microscope. Results After 3d of infection with rAAV-EGFP ,slight fluorescence was detected in rabbit cornea by fluorescence stereoscope .

微型角膜刀制作兔角膜基质瓣；转染组用含rAAV－EGFP转染液浸泡角膜瓣和角膜基质床10 min，对照组用等量BSS液浸泡角膜瓣和角膜基质床10 min，不同时间点(1、3、7、14、21d)通过荧光体视镜观察角膜出现EGFP荧光的起始时间及分布情况，收集角膜，其中一半用激光共聚焦显微镜观察、照相，另一半固定后行HE染色。

Abstract］ Objective To study the influence of different residual cornea bed of laser in situ keratomileusis on the collagenic construction of cornea through investigating the expression of matrix metalloproteinases and tissue inhibitors of metalloproteinases in cornea cells for different residual stroma bed after LASIK for six months.

目的 研究不同切削厚度的准分子激光原位角膜磨镶术（laser in situ keratomileusis，LASIK）后兔眼基质金属蛋白酶（matrix metalloproteinases，MMPs）及基质金属蛋白酶组织抑制剂(tissue inhibitors of metalloproteinases，TIMPs)的表达，以探讨LASIK手术的不同切削深度对角膜的胶原结构的影响。

The article elaborates the basic theory and mathematics model of ablating cornea by Excimer Laser, makes out the model which partition the cornea ablation area to 30 or 60 ablating circles, and arrives at the error of real calculation corve and academic model curve by comparing a with them under the help of MATLAB software, achieves the success of coney experiment and blind eyes' experiment, thus establishes the clinical experiment basis of cornea ablation in advance.

文章论述了准分子激光消融眼球角膜的基本原理和数学模型，提出了把角膜治疗区域有目的地划分成30个或60个消融道的模式，通过MATLAB软件把理论计算曲线和实际模型曲线进行比较，得出它们的消融误差，并且成功进行了动物实验和盲眼实验，提前为角膜屈光的临床实验奠定了基础。
