简介：目的：探讨超声乳化术治疗特殊类型白内障的安全性和有效性。方法：回顾性分析临床资料，研究超声乳化吸出（联合）人工晶状体植入术治疗青光眼术后白内障、小瞳孔白内障、葡萄膜炎并发白内障和外伤后并发白内障等特殊类型白内障的技术要领。结果：进行治疗的73例84眼特殊类型白内障患者中，单纯行超声乳化术27例28眼，植入后房型人工晶状体52眼，植入前房型人工晶状体4眼；术后1mo平均眼压12.72±2.63mmHg，脱盲率99%，脱残率96%；并发症发生率4%。结论：特殊类型白内障手术难度大，超声乳化术切口小，可保留晶状体后囊膜和植入人工晶状体，是摘除特殊类型白内障的理想术式。

简介：目的分析Nd：YAG激光行后囊膜切开术治疗白内障复明手术后不同类型后发性白内障的治疗作用与术后并发症。方法对白内障复明手术后,109例（109眼）后发性白内障依据后囊昆浊形态分为：A组Elschnig珍珠样小体型46例（46眼）,B组纤维化型63例（63眼）。采用十字形切开法或开罐式切开法进行激光后囊膜切开术,比较两组激光术前最佳矫正视力与激光术后最佳矫正视力以及激光术后并发症情况。结果A、B两组内激光术后最佳矫正视力较激光术前最佳矫正视力改善（P〈0.05）;A组术后眼压升高和房水闪辉明显高于B组（P〈0.05）。结论Nd：YAG激光是治疗白内障复明手术后不同类型后发障的常用有效的治疗方法,激光术后并发症与后发性白内障类型有关。

简介：目的通过对我区学校视力监测点监测结果进行分析,了解儿童、青少年视力不良的发展动态.方法对我区2000～2001年二所中学二所小学二所幼儿园视力监测结果进行统计分析.结果(1)二所中学二所小学二所幼儿园学生视力不良以屈光不正为主.(2)屈光分析表明近视屈光不正发病率中学最高,占91.85%;其次是小学,占53.47%,但以轻度近视为主;幼儿园学生以远视屈光不正发病率为高,占74.52%,以轻度远视为主.(3)随着年龄的增长,学习任务的增加,视力不良、近视屈光的发生率增加.结论在中小学、幼儿园中进行视力监测和屈光状态分析可早期发现屈光不正和弱视,及时防治,对控制小学生视力不良有重要意义,为了今后更好地做好视力不良的防治工作还需教育、预防、临床等部门密切配合和政府部门政策性的支持.

简介：目的观察白内障冷冻囊内摘除术后二期人工晶状体植入疗效.方法对134例134眼白内障冷冻囊内摘除术后元晶状体眼随机分为两组,第一组弹性开放襻前房型人工晶状体植入组共70眼;第二组为后房型人工晶状体缝线固定组共66眼.结果两组病例术后矫正视力均达到术前矫正视力或超过,矫正视力0.5以上超过60%,两组病例视力差异元明显统计学意义.结论白内障囊内摘除术无晶状体眼两种类型人工晶状体二期植入均具有良好的治疗效果.

简介：教育能够改变个人的生活,促进社会的变革。儿童在学校学习成绩的好坏,与他们的健康水平,包括视觉健康之间有着密切的联系。这反过来又影响到儿童未来的生活质量与经济生产力。学校的眼睛健康项目给上学儿童们提供了一个独一无二的机会,使他们能拥有全面的眼睛健康服务。
