简介:据我国卫健委数据显示,2022年中国儿童青少年总体近视率为53.6%,其中6岁儿童为14.5%,小学生为36%,初中生为71.6%,高中生为81%。青少年近视呈上升趋势,近视年龄低龄化,需要加强近视防控。
简介:目的通过观察使用和不使用白星技术行超声乳化白内障吸出术后的效果,探讨白星超声乳化技术的优点.方法随机选取40例硬核(Ⅲ~Ⅳ级)白内障患者共47眼,随机分为A、B两组行超声乳化白内障吸出并人工晶状体植入术,A组使用白星技术,B组使用普通的超声乳化技术.对比两组手术后视力恢复情况、角膜水肿情况、超声乳化能量及每组手术前后角膜内皮计数减少量.结果A组与B组术后恢复较好视力(≥0.7)的比例差异无显著性,A组术后第一天的角膜水肿情况明显好于B组,手术前后角膜内皮细胞丢失数量明显少于B组,所用超声乳化的平均能量明显低于B组.结论白星技术所用能量少,术后反应小,组织损伤小,恢复快,值得临床推广应用.
简介:目的探讨一种规范化的的高度近视白内障超声乳化方式,总结手术注意点。方法选取高度近视白内障患者91例(91眼)均予以超声乳化联合人工晶体植入术治疗并总结。结果所有病例的术后裸眼视力均优于术前裸眼视力。术后第1天裸眼视力≥0.2共72眼(79.12%),≥0.5共37只眼(40.66%);术后3月裸眼视力≥0.2共85只眼(93.41%),≥0.5共42只眼(46.15%)。最佳矫正视力≥0.2共89只眼(97.80%),最佳矫正视力≥0.5共72只眼(79.12%)。术前散光度平均1.10D±0.78D,术后3月散光度平均1.25D±0.72D。术后散光度与术前散光度比较,差异无显著性(t=1.166,P=0.261)。无瞳孔严重变形、视网膜脱离、囊样黄斑水肿、瞳孔夹持、青光眼以及顽固性葡萄膜炎等并发症。结论低能量,高负压,低灌注,连续环形撕囊,双手劈核技术对于高度近视白内障患者更加安全有效。

简介:目的了解531例患者(含家属)对我院民生工程白内障手术疗效的评价。方法我院固定1名眼科主治医师在不同时间段进行电话回访(含手机),如固定电话打不通再换手机打,打1-2次通话者为1次打通,3次(含3次者)以上为多次打通,打4-7次不通者放弃。结果531例共打电话1327次,平均每名患者2.49次,回访率为100%,最终获得有效通话者427例,回访成功率为80.41%。手术满意380例,占88.99%;基本满意33例,占7.73%;满意率为96.72%。不满意14例,占3.28%。术后复查1-3次者314例,占73.53%;未复查93例,占21.77%;不知道是否复查20例,占4.68%;复查率最高者琅琊区100%,最低者定远县63.44%。无1例在住院手术期间花钱。未发现严重并发症和医疗事故及医疗纠纷。结论电话回访能有效获得民生工程白内障手术患者的疗效评价,且经济方便,应纳入常规内容。
简介:目的评价甲基纤维素联合透明质酸钠制作软壳技术在白内障小切口非超声乳化手术中的效果.方法白内障“复明工程”患者261例295眼.随机分为A、B两组,其中A组术中单用透明质酸钠,B组术中联合使用甲基纤维素和透明质酸钠.手术方法为小切口非超声乳化加人工晶体植入.结果术后第ld裸眼视力大于0.3者,A组78.79%(104/132),B组87.1%(142/163),两组之间差异显著(P<0.05);术后第7d视力在0.3以上者,A组93.9%(124/132),B组94.5%(154/163).两组间差异无统计学意义(P>0.05).术后角膜水肿情况:术后第1天,A组17.42%(23/132),B组9.8%(16/163),两组间比较差异有统计学意义(P<0.05).术后第7天,A组2.27%(3/132),B组2.45%(4/163),两组间比较差异无统计学意义(P>0.05).结论甲基纤维素联合透明质酸钠制作软壳技术比单用透明质酸钠更安全.
