目的观察1.2mm微切口白内障超声乳化术后散光动态变化.方法将75例(89只眼)老年性白内障患者随机分为两组,一组34例(40只眼)行双手超声乳化术,切口为1.2mm,植入Acri.Smart人工晶状体.另一组41例(49只眼)行传统超声乳化术,切口为3.2mm,植入AR40e人工晶状体.术前及术后1周、1月、3月行眼科常规检查及角膜地形图检查.分析患者术后视力和角膜地形图改变.结果术后1d、1周双手组裸眼视力好于传统组,差异有统计学意义(P＜0.05).术后1周、1月双手组散光度数小于传统组(P＜0.05),术后1周、1月双手组的手术源性散光小于传统组(P＜0.01).传统组术后1周的SRI和SAI较术前增加,双手组术后1周的SRI和SAI小于传统组.双手组术前术后角膜地形图改变极小.结论 1.2mm微切口白内障超声乳化术切口小,对角膜形态影响小,散光小,视力恢复快.

Objective To observe the changes of astigmatism of 1.2mm micro-incision phacocmulsification with corneal topography.Methods Seventy-five patients (89 eyes) with age-related cataract were divided into two groups in random.Thirty-four patients (40 eyes) were treated with bimanual microphacoemulsification which incision was 1.2mm and implanted with Acri.smart IOL while other 41 patients (49 eyes) were treated with conventional phacoemulsification which incision was 3.2mm and implanted with AR40e IOL.The visual acuity,changes of corneal topography were observed.Results The uncorrected visual acuity of bimanual group was bctter than conventional group in 1 day and 1 week after surgery (x~2=7.673,6.027,P=0.022,0.049＜0.05).The astigmatisms of bimanual group were significantly lower than conventional group in 1 week and 1 month after surgery (t=-2.778,-2.050,P=0.012,0.042＜0.05).The surgery induced astigmatisms of bimanual group were significantly lower than conventional group in 1 week and 1 month after surgery (t=-3.271,-3.107,P=0.004,0.004 ＜0.05).The surface regularity index and surface asymmetry index of bimanual group were lower than conventional group in 1 week after surgery.Conelusions The astigmatism of 1.2mm micro-incision phacoemulsification is very low and can get better visual acuity.
