Corneal epithelial implantation is 5 in 2000(0.25%). The rate of diffuse intralamellar keratitis is 5.5%(110/2000); corneal opacity are 2 in 2000(0.1%). Group B: Free cap are 2 in 500(0.4%); Corneal epithelial implantation is 1 in 500(0.2%);Diffuse intralamellar ketatitis are 27 in 500(5.4%), not any incomplete cap,broken flap and corneal opacity happened.

结果 A组：不完全瓣21眼占1.05%（21/2000）；游离瓣13眼占0.65%（13/2000）；碎瓣1眼占0.04%（1/2000）；角膜上皮植入占0.25%（5/2000）；弥漫性板层角膜炎占5.5%（110/2000）；角膜混浊2眼占0.1%（2/2000）。B组：游离瓣占0.4%（2/500）；角膜上皮植入占0.2%（1/500）；弥漫性板层角膜炎占5.4%（27/500），无不完全瓣、碎瓣及角膜混浊发生。

The thinner, weaker post-LASIK cornea is more susceptible to forward bulging due to normal intraocular pressure, which may progress to a condition known as keratectasia and corneal failure, requiring corneal transplant.

LASIK术后更薄，更弱的角膜相对正常眼压的压力来说，是更易膨胀的，发展下去，可能导致被称为角膜膨胀和角膜病变的疾病，最后需要角膜移植。

Our investigation demonstrates that before refractive surgery the keratometer has a similar clinical value as that of corneal topography, and the △ Sim K value is related to the graphic pattern of corneal topography.

角膜曲率计与角膜地形图对术前角膜散光测量具有相似的临床价值，角膜地形图图形与参数△Sim K值有关。

Methods: A total of 366 eyes with keratoconus were subjected to wear proper RGPCL. Keratometer and corneal topography were used to determine the central cornea astigmatism, apex K value, apex decenteation distance, SRI and SAI before, 12 and 18 months after wearing RGPCL.

对圆锥角膜患者选配合适的高透氧RGPCL，分别于配戴前及配戴后12、18个月行角膜曲率计和角膜地形图检查，采集角膜中央散光值、锥顶K值、锥顶偏心距离、SRI、SAI等参数，进行统计学分析。

There were some specific examinations according to conditions of different patients, including multipoint corneal thickness, time-related keratometry, glare, contrast sensitivity, function of muscular apparatus, VEP, and so on.

除视力、屈光度、主视眼、角膜厚度、角膜地形图、像差检查等常规术前检查外，还要依据患者情况进行相应的特殊检查，包括角膜多点厚度、角膜曲率时间变化、眩光仪、对比敏感度、眼肌功能、VEP五项等检查。

The corneal thickness was measured with ultrasonic corneal pachymeter before enucleation and the corneal endothelial cell density was counted with non-contact specular microscope after enucleation in two groups.

两组均在眼球摘除前以角膜测厚仪测量角膜厚度，眼球摘除后以非接触角膜内皮显微镜行角膜内皮细胞计数。

For patients with high-risk mycotic corneal ulcer, the conservative therapy was uneffective, but PKP is an effective approach for preservation of eyeballs and restoration of visual function.

对于保守治疗无效的高危真菌性角膜溃疡患者，穿透性角膜移植是挽救眼球和视力的有效方法。关键词：角膜移植；角膜溃疡；真菌病

Primary and high school students are undergoing fast physical development the visual axis hasn't jelled yet wearing contact lenses too early or too much could generate the side effects such as the hypoxia of cornea and the disturbance of physiological metabolism. It will cause secondary bacterial pneumonia if the lenses are not cleaned and sterilized completely. The maladjustment of lens labyrinth and cornea would also wear out the corneaexfoliate the endepidermis even can lead to the corneal ulceration and perforation .

中小学生正处在生长发育旺盛时期，眼球视轴尚未定形，若过早或较长时间连续配戴隐形眼镜易产生角膜缺氧和生理代谢障碍等副作用；镜片清洗消毒不严，则会继发感染；镜片曲径若与角膜不相适应，还会造成角膜磨损，上皮脱落，严峻者会导致角膜溃疡或穿孔。

Methods:Based on the measured diopters,278 patients (538 eyes) that were to receive PRK operation were divded into 4 groups:mild,medium,high,and superhigh myopia,respectively.

目的：通过测量近视眼的角膜屈光力、眼轴和角膜中央厚度，分析角膜屈光力、眼轴和角膜中央厚度与近视程度的关系。

RESULTS: In Phaco group, 79.2％ of the patients visual acuities at the first day after operation were≥0.3. In this group, the nuclear hardnesses of some patients catract were ≤Ⅲ, and others ≥Ⅳ; complications occurred in the former including capsule rupture and vitreous prolapse(4.3%), corneal edema (22.2%); while the latter were 13.7% and 68.6%, respectively.

结果：Phaco组视力≥0.3者79.2%，核硬度≤Ⅲ者后囊膜破裂玻璃体脱出发生率4.3%，角膜水肿发生率22.2%，核硬度≥Ⅳ者后囊膜破裂玻璃体脱出13.7%，角膜水肿68.6%；MSICS组视力≥0.3者78.1%，核硬度≤Ⅲ者后囊膜破裂玻璃体脱出发生率3.8%，角膜水肿发生率19.0%，核硬度≥Ⅳ度者后囊膜破裂玻璃体脱出发生率5.7%，角膜水肿发生率14.3%。

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。
