简介：质量是一个难以描述及定义的概念。人们对质量的评定各有不同的见解。拿出租车旅行来打个比方。你如何评定旅行的质量？你的评定时基于司机是否有礼貌还是车子的豪华程度？或者以你安全到达目的地为标准？如果让你的司机来评价同样一场旅行的质量，他们可能认为旅途中没有抛锚或没有被交通事故耽搁就是好。评定质量有很多不同的标准，以那一点为准取决于你的角色。

简介：目的：评价青光眼患者的生存质量并探讨影响其生存质量的因素。方法：采用国家眼科研究所视功能问卷-25,对126例青光眼患者的生活质量进行评价。结果：青光眼患者的生存质量普遍下降,不同程度的视力损害明显影响着患者的生存质量得分（P〈0.01）。多因素逐步直线回归显示：生存质量的得分与年龄、经济收入、遵医行为有密切关系（P〈0.05）。结论：在保护青光眼患者视功能的同时,要重视其社会、心理等因素,给予其必要的健康教育和心理辅导,以期提高其生存质量。

简介：目的通过安徽省某县09年度与11年度分别开展的贫困白内障复明手术各300例（300眼），手术结果的比较，探讨防盲手术培训的重要性。方法手术均由通过培训与再培训并获得资格认证的两位医生完成。术前视力〈0．1，排除其他眼病及严重全身疾病。手术方式统一为小切口非超声乳化白内障摘除及人工晶状体植入术，植入的人工晶状体均为Alton晶状体，粘弹剂为玻璃酸钠（其胜，上海产）。术前、术后处理按照安徽省防盲手术要求执行。结果比较两年度病人的早期术后视力，术中及术后早期并发症，09年度与11年度比较，术后第一天裸眼视力≥0．3比率由49．5％上升至60．4％；术中玻璃体脱出由7％降至4％；角膜水肿发生率由16％降至11％；其他并发症同样明显减少。而每例白内障手术时间也由40分钟减少至22分钟。结论11年度手术质量明显好于09年。并且09年手术是在省防盲中心派一名教师现场指导下完成，而11年度则是完全是独立完成。这些结果均提示通过有效的防盲手术培训，能以明显的提高白内障手术质量；同时也充分证实了防盲手术培训是非常重要的。

简介：对有晶状体眼植入后房型人工晶状体是矫正屈光不正的有效方法，植入的后房型人工晶状体目前主要有可植入式接触镜（implantablecontactlens，ICL）和有晶状体眼屈光性晶状体（phakicrefractivelens，PRL）。对术后患者主观视觉质量（视力、对比敏感度）、客观视觉质量（波前像差、点扩散函数、斯特尔比率及光学传递函数）的研究显示，主观视力的提高也伴随着客观视觉质量的改善，但部分患者术后出现光晕及眩光症状。本文主要对ICL和PRL植入术后主观及客观视觉质量的临床研究做一综述，对可影响视觉质量的术后并发症如晶状体前囊膜下混浊、青光眼及角膜内皮功能异常等需进一步远期随访。

简介：目的探讨防盲活动中贫困白内障手术质量控制方法。方法年终检查时（距手术后最短时间为一个月,大部分都在术后三月以上）设计了一套质量评估方案,即随机、按一定的比例进行检查,包括按8%抽查病历,2%电话随访,0.5%现场入户检查。结果2009年我省贫困白内障手术任务13000例,实际完成13308例。手术方式主要为小切口非超声乳化白内障摘除及人工晶体植入术,其中8%的病人采取了超声乳化手术。病历抽查：93%的病历能按省卫生厅和省防盲办要求的规范执行,其中观察术后矫正视力〉0.3达91.23%,人工晶体植入率97.82%。电话随访结果是老百姓对该项工程满意率达92.30%。现场入户调查结果,对手术效果（100分）评分98.87,对政府组织（100分）等评分99.98,现场视功能检查（包括日常生活对视力的需求）评分（总分40分）37.43。术后并发症发生率﹤5%,主要表现为瞳孔变形和后发白内障。结论按一定比例,随机采取病历检查、电话随访和现场入户相结合的方法进行调查,是贫困白内障患者复明工程手术质量的良好控制方法。

简介：目的：探讨近视患者配戴角膜塑形镜（orthokeratology,Ortho-K镜）前后视觉质量的变化情况。方法：选取江苏省溧阳市中医院眼科验配角膜塑形镜55例110眼青少年近视患者,在戴镜前、戴镜后7d,1、3、6mo五个时间点利用OQASTMⅡ视觉质量分析系统和Topolyzer角膜地形图进行检测,分别获得各参数：眼散射指数（opticalscatteringindex,OSI）、MTF截止频率（MTFcutoff）、斯特列尔比（Strehlratio）、OQAS值（OV100%、OV20%、OV9%）、高度不对称性指数（indexofhighestasymmetry,IHA）、高度离心指数（indexofhighestdecentration,IHD）和不规则指数（aberrationcoefficient,ABR）。结果：角膜塑形镜戴镜前裸眼视力为0.21±0.13,戴镜后7d,1、3、6mo分别为0.48±0.15、0.72±0.14、0.93±0.13、1.02±0.13,差异有统计学意义（P〈0.05）。OSI配戴前与配戴后1、3、6mo比较具有统计学差异（P〈0.05）。MTFcutoff配戴前与配戴后1、3、6mo比较具有统计学差异（P〈0.05）。Strehlratio配戴前与配戴后1、3、6mo比较具有统计学差异（P〈0.05）。OV9%配戴前与配戴后1、3、6mo比较具有统计学差异（P〈0.05）。IHA配戴前与配戴后1、3、6mo分别为4.13±3.59、19.11±15.38、17.78±17.12、34.18±23.34,与配戴前相比差异均有统计学意义（P〈0.05）。IHD配戴前与配戴后7d,1、3、6mo分别为0、0.02±0.01、0.02±0.02、0.03±0.02、0.03±0.01,与配戴前相比差异均有统计学意义（P〈0.05）。ABR配戴前与配戴后7d,6mo分别为0.29±0.51、1.23±0.71、2.10±0.59,与配戴前相比差异均有统计学意义（P〈0.05）。结论：夜戴型角膜塑形镜可引起视觉质量的下降,但下降程度轻微。角膜塑形镜治疗青少年初发性近视效果确切,角膜塑形镜能快速、有效地提高裸眼视力,在控制青少年近视发展方面是值得肯定的。
