角膜的

It is done with a knife called microkeratome and is used to cut a flap in the cornea.

这是做的所谓的角膜刀，是用来切瓣的角膜。

Methods Corneal epithelial cells of limbal, peripheral and centeral cornea were removed using improved enzymatic disaggnegation and cultured in vitro. The cells were counted in a hemocytometer at different time to determine the doubling time .

用体外细胞培养的方法，从生长曲线、细胞倍增时间、细胞DNA合成的活跃程度等几个方面，观察人角膜缘部、周边部及中央部角膜上皮细胞的生长特征。

T show evidence of toxicity between the verapamil treated animals and control animals.conclusionsubconjunctival verapamil decreased the incidence of tractional retinal detachment due to traumatic proliferative vetreoretinopathy in this rabbit model.verapamil at the dose used in this model has no evident toxicity on rabbit eyes.further studies are needed to determine the doseresponse and efficacy of the drug.

结果在模型制备后第35天，治疗组18只眼发生牵引性视网膜脱离，占56.3%，对照组26只眼发生，占81.3%(χ2=4.655，p=0.031)；玻璃体视网膜增生程度治疗组较对照组明显减轻(秩和检验，u=3.5419，p＜0.001)；未发现ver对角膜上皮有明显毒性反应。结论结膜下注射ver能有效抑制外伤性pvr的发展，减少牵引性视网膜脱离的发生率；ver在实验所用剂量对角膜上皮无明显毒性反应。

Treatment of presbyopia with Monovision may use unifocal contact lens, implantation of intraocular lens, photo refractive keratectomy, laser in situ keratomileusis, and conductive keratoplasty that is update and nonexcimer laser refractive surgery technique.

Monovision矫正方法常用于老视和老视前期患者，即一眼矫正看远，另一眼矫正看近，其机制是双眼间的模糊抑制，MV可应用于单焦点角膜接触镜，并且还可应用于人工晶状体植入术和PRK，LASIK等激光屈光手术中，以及目前最新的非激光手术—传导性角膜成形术。

This ablates a central, steepened zone for near correction, and a peripheral zone targeted for distance.

这种技术为术后的视近能力在角膜中央区域切削比较陡峭，而在角膜周边区域的切削是为取得视远能力。

Chitosan and its acetylated derivatives have been widely applied in the nerve, cartilage, bone tissue engineering.

观察兔角膜上皮细胞和基质细胞在膜上的生长情况，研究不同类型壳多糖膜与角膜细胞的生物相容性。

COX-2 modulates the expression of VEGF,playing a very important role in CNV.

①COX-2在炎症性角膜新生血管形成过程中表达上调，其调控VEGF的表达，在角膜新生血管的形成过程中起着重要作用。

To evaluate the characteristics of the rabbit dry eye model. Method The S1T value, corneal fluorescein and rose Bengal staining before and after lacrimal gland extirpation were graded. The cornea was taken for transmission electron microscopic examination.

摘除兔泪腺和Harder氏腺，比较泪腺摘除前后S1T、角膜荧光素染色和虎红染色分值的变化，并在透射电镜下观察角膜上皮形态学的变化。

Objective: To investigate the expression of inducible nitric oxide synthesis in cornea after alkaline burn, and to observe the effect of topically applied N-Nitro-L-Arginine Methyl Ester on corneal neovascularization in rats.

目的：探讨碱烧伤后角膜新生血管形成过程中诱导型一氧化氮合成酶的表达及作用；观察局部应用硝基左旋精氨酸甲脂对角膜新生血管形成的影响。

Tearing and squinting are the most likely signals of corneal abrasions, and sometimes with the penlight directed at an angle, the abrasion or ulcer on the cornea is visible.

撕裂和眯眼是最有可能的信号角膜擦伤，有时与penlight针对一个角度来看，磨损或溃疡的角膜可见。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
