objective:to investigate the changes of corneal astigmatism after trabeculectomy and analyse the causes.
目的:观察小梁切除术后角膜散光的变化,并分析其原因。
mean corneal astigmatism was not significantly different before surgery and at the 3rd month after surgeries(p>0.05). posterior capsule rupture occurred in 4 cases (3.74%).
角膜平均散光度术后3个月与术前比较差异无统计学意义(p>0.05),术中4眼出现后囊膜破裂(3.74%)。
conclusion corneal astigmatism was the main cause of differences of compound myopic astigmatism and simple myopic in corneal surface shape.
结论角膜散光是复性近视散光与单纯近视之间角膜形态差异的主要原因。
objective study on cataract extraction and iol implantation with small or conventional incision for the visual acuity and corneal astigmatism after operation.
目的探讨小切口与常规切口对白内障术后视力和角膜散光的影响。
corneal astigmatism in small incision group was significantly less( p visual acuity was much better than in conventional incision group( p 0 05).
结果小切口组比常规切口组视力恢复快、散光小,两组相比有显着性差异(p 0 .0 5 )。
conclusion if incision location away from the corneal refractive center is farther, mean corneal astigmatism is smaller in the early time postoperatively.
结论切口所处位置距角膜屈光中心的距离越远,术后早期平均角膜散光度越小。
objective study the effect in ocular vision, corneal astigmatism and retinopathy after phaco with diabetic cataract.

among them, the impact of corneal astigmatism becomes a major factor in postoperative visual quality.
术后的角膜散光成为影响术后视觉质量的主要因素。
the traditional large incision extracapsular cataract extraction surgery often caused a surgically induced corneal astigmatism which had great impact on fuming effect.
传统的大切口白内障囊外摘出术常造成较大的手术源性角膜散光,影响复明效果。
objective:to evaluate the clinical effect of the patients distance vision, near vision and corneal astigmatism by foldable multifocal intraocular lens(miol).
目的:评价白内障超声乳化多焦折叠人工晶体(miol)植入术后的远、近视力、角膜曲率变化的临床效果。
tunnel incision can make the surgery process easier and induce corneal astigmatism smaller.
与传统角巩膜缘切口比较,术中眼压维持稳定,术后手术性角膜散光度数小。
it could reduced corneal astigmatism to suture conventional incision postoperatively.
常规缝合切口会明显减少术后角膜散光。
