摘要
目的：研究手术切口大小对白内障术后视力和角膜的影响。方法：将患者分成A、B两个组后，均使用卡尔·蔡司手术显微镜（Carl Zelss Stativ S88）和芙固爱尔康白内障起声乳化仪（AIcon Infiniti Vision System）。分别对两组患者进行3．5毫米透明角膜切口和6毫米反眉弓形巩膜隧道切口白内障超声乳化术28眼和36眼，然后用多荧Tomey角膜地形图仪TMS-4对患者角膜形态参数进行计算分析。结果；A、B两组患者在术后7天时角膜散光度有较明显差异，3．5毫米角膜组于术后30天起无明显差异，6毫米巩膜组于术后90天才没有明显差异。术后30天，角膜组的散光度数低于巩膜蛆散光度数。术后7天角膜组SRI值要明显低于巩膜组，而SAI值却无组间差异。两组术后7天时，SA1及SRI值均高于术前水平，90天时恢复至术前水平。结论：实施3．5毫米透明角膜切口超声乳化术效果较好，术后患者视力和散光恢复较快，角膜形态改变较小．
Objective：To study the influence of operation incision size on postoperative visual acuity and cornea in cataract patients. Methods：The patients were divided into A and B groups, using Carle Zeiss Stativ S88 operation microscope and American Alton Infiniti Vision System, respectively for the two groups of patients hy 3.5mm clear corneal incision and 6turn anti superciliary arch sclera tunnel incision phacoemulslflcation in 28 eyes and 36 eyes, and then use Tomey TMS--4 in patients with corneal topography corneal morphology parameters were calculated and analyzed. Result： 7 days later,A and B two group patients＇s corneal astigmatism are obviously different, 3.5 mm corneal group on the 30 postoperative day without ob- vious difference, 8 mm scleral group from postoperative 90 days did not differ significantly. 30 days later, the degree of astigmatism corneal group below the scleral group astigmatism. 7 days later , eorneal group＇s SRI value was lower than the scleral group＇s, and the SAI value was no difference between the two groups; 7 days after operation, SA1 and SRI values were higher than the preoperative level, but 90 days later, returned to the preoperative level. Conclusion：The implementation of 3.5 mm clear corneal incision phacoemulsiflcation effect is better, postoperative visual acuity and astigmatism were fast reeovered,and corneal shape changes smaller.
