角膜切除术

It goes by two names: Surface ablation, or wavefront-guided PRK, which stands for photorefractive keratectomy.

它有两个名字：表面烧灼和波正面向导的PRK，这代表光折变角膜切除术。

Objective To observe the possibility of endothelial cell damage after photorefractive keratectomy.

目的 观察激光角膜光学切除术(photorefractive keratectomy，PRK)对角膜内皮细胞损伤的可能性。

The mass was excised by superficial keratectomy and the bare stroma covered with amniotic membrane.

用表浅角膜切除术切除了团块联合羊膜覆盖其下裸露的角膜基质。

Purpose: This report presents our experience with excimer laser photorefractive keratectomy on 63 myopic eyes, and makes a comparison of the results of PRK performed using two different ablation profiles.

目的：这篇报告提出用准分子雷射屈光性角膜切除术治疗近视的经验，並比较使用不同切割方式所得的结果。

Purpose: To evaluate the efficacy and safety of Mitomycin-C use in inhibiting haze formation of photorefractive keratectomy eyes following undercorrected radial keratotomy.

目的：以雷射屈光角膜切除术并用Mitomycin-C治疗屈光欠矫之放射状角膜切开术病例，评估其安全性及抑制术后角膜雾浊的效果。

Secondary glaucoma developed in 6 of 9 eyes subsequent to iris atrophy (4 eyes) or a cyclitic membrane (2 eyes), and 3 eyes underwent trabeculectomy.

白内障囊外摘除术在角膜移植术同时或之后予以实施。9只眼中有6只眼发生了继发性青光眼，其中4只眼是由于虹膜萎缩，2只眼为睫状体炎性假膜。3只眼被予以小梁切除术。

In regarding the treatment of corneal dermoid depended on the extent of involvement of the cornea, lamellar keratoplasty in corresponding position can lower the recurrent rate.

治疗角膜皮样瘤应根据角膜受累程度采用不同的手术方式，相应部位的角膜皮样瘤切除联合板层角膜移植术可以减少术后复发的几率。

This article summarized the influence factor of ametropia after PKP and the main treating methods, including wearing on the glasses or adhesive glasses, taking out stitches of cornea selectly, loose the cut, etc.

对影响PKP术后屈光状态的因素及其主要矫治方法如配戴框架眼镜或角膜接触镜、选择性角膜拆线、松弛性切口、散光性角膜切削术、角膜楔形切除术、放射状角膜切开术、准分子激光手术等进行简要综述。

In an attempt to evaluate the safety and efficacy of Healon in trabeculectomy, 20 eyes with Healon and 20 eyes without Healon injection after trabeculectomy are compared. Trabeculectomy using Healon will not induce transient rise of intraocular pressure. By filling the anterior chamber with Healon, a tamponing effect results which will maintain a deep chamber and reduce complications such as flat anterior chamber, choroidal detachment and striate keratopathy in the early postoperative period. In long-term evaluation there is no difference in pressure control, conjunctival scarring and corneal endothelial cell loss between Healon group and Non-Healon group.关键词 trabeculectomy , flat anterior chamber , choroidal detachment , intraocular pressure

为了评估Healen在小梁切除术中之疗效及安全性，选20位接受小梁切除术者，同时注射Healon於前房为实验对象，另20位接受传统小梁切除术为对照组，发现使用Healon并不会引起一过性眼压上升的现象，Healon注入前房，产生填塞作用，最大的好处是可以维持前房深度，减少术后合并症如前房消失，脉络膜剥离及角膜水肿等，然长期追踪，对於降眼压的幅度，不因使用Healon而可达到低眼压状态，也不会减少结合膜瘢痕化而促进房水引流，然Healon系一无毒，无炎性，无抗原性高黏稠性的物质，不因使用而发生炎性反应，同时有保护角膜内层细胞的功能。

Surgical excision can significantly improve induced abnormal corneal topographic changes and reduce corneal astigmatism from pterygia.

翼状胬肉切除术能明显减少角膜散光，改善术前角膜地形图的不规则形态，有利于提高视力和视觉质量。

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。
