查询词典 corneal

The mean diopters of corneal astigmatism compared with that before the surgery had no significant difference in the group A, and had significant difference in the group B, at 1st month after the operation.

术后前房闪辉、角膜水肿、后囊混浊、人工晶状体移位的发生率A组显著低于B组。A组人工晶状体在前房内的破损率和翻转率分别为2.9％和1.0％。

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%。

PURPOSE. To investigate relationships between acute intraocular pressure–induced optic nerve head surface deformation and corneal hysteresis and thickness in glaucomatous and nonglaucomatous human eyes.

目的：研究在青光眼和无青光眼性损害的人眼中，急性眼压升高引起的视乳头变形与角膜滞后值和角膜厚度之间的关系。

In addition, we use contrast sensitivity and contrast acuity as indicators of visual function and try to investigate: 1 the impact of aging on corneal and total ocular HOAs 2 the change of HOAs after the cataract surgery 3 to compare intraindividually the HOAs and functional vision between implantation of spherical and aspherical IOLs.

二、接受白内障超音波乳化术并人工水晶体植入的病人手术前后角膜及眼球整体高阶像差的变化。三、比较接受白内障超音波乳化术并植入传统球面人工水晶体，或新型态非球面人工水晶体术后高阶像差及视觉品质的不同；并分析其可能影响因子。

The results reveal that: Corneal HOAs, including total 3rd, total 4th, total 5th order, coma and primary spherical aberrations, have minimal changes with increase of age.

研究结果发现：随年龄增加，各阶角膜像差无变化，眼球整体高阶像差渐增，是由於水晶体随年龄变化造成球面像差渐增所致。

After the small incision clear cornea cataract surgery with , the corneal HOAs increase minimally, but the total ocular HOAs increase significantly compare to normal phakic eyes, especially the total 4th order and primary spherical aberrations.

白内障手术前后角膜高阶像差无变化；手术后眼球整体球面高阶像差增加，主要是由於植入传统球面人工水晶体造成。

A highly hydrophobic nature and relatively high molecular weight of FK506 limit corneal penetration without resulting in effective intraocular drug kevels.

另外，FK506滴眼剂体外检测的方法学尚未建立，对滴眼剂质量和稳定性尚不了解，成为新药申报和审批的障碍。

Intraocular surgery has been used for refractive corrections with the development of aspheric intraocular lenes capble of correcting high order corneal aberration.

白内障手术已经进入屈光手术时代。新型的可以矫正角膜高阶像差的非球面人工晶状体已经陆续问世。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
