To evaluate the outcome of cataract surgery in elderly population in Doumen County, Guangdong Province by assessment of subjective visual function and quality of life.
All the cataract postoperative subjects were identified in the population-level. Visual Function and Quality of Life (VF/QOL) questionnaire developed by National Eye Institute, USA in developing countries was used as the instrument. This Questionnaire was administered by four trained-interviewers in all subjects with visual acuity less than 0.1 in either eye (treated as visual impairment cases), One in every 20 persons with visual acuity better than 0.3 (treated as normal control cases) in both eyes (un-operated group) and all cataract postoperative cases (operated group).
In 5 342 cross-sectional examined persons, individuals who could be successfully interviewed included 99 (90.8%) cataract postoperative cases, 535 (85.5%) visual impairment cases and 119 normal control ones. On a 0 - 100 scale, medium total scores of VF and QOL diminished from 92 to 2 and from 100 to 19 respectively along with visual status from normal to severe blindness in the un-operated group. Similar findings on visual status and VF/QOL scores were found in the operated group. The overall scores of VF and QOL were 40 and 56 for operated one and 56 and 72 for un-operated one. After adjusted the confounding effect of visual status, age, sex and education by multivariate regression model, the difference of QOL scores between un-operated and operated group was significant (P = 0.015), while no significant difference (P = 0.199) was found in VF scores.
The scores of VF and QOL are significantly correlated with the visual status. Subjective visual function and quality of life could not be significantly improved after cataract surgery in this target population. Concerns should be paid in postoperative follow-up, aphakic correction and social-psychological rehabilitation.
通过评估主观视觉功能和生活质量，评价广东省斗门县老年人群白内障手术的效果。
在人群层面识别所有白内障术后受试者。采用美国国立眼科研究所为发展中国家开发的视觉功能与生活质量（VF/QOL）问卷作为工具。该问卷由四名经过培训的访谈员对所有单眼视力低于0.1（视为视力损害病例）的受试者、双眼视力优于0.3的每20人中的一人（视为正常对照病例）（未手术组）以及所有白内障术后病例（手术组）进行发放。
在5342名横断面检查的人群中，能够成功访谈的个体包括99名（90.8%）白内障术后病例、535名（85.5%）视力损害病例和119名正常对照者。在0 - 100分的量表上，未手术组中，随着视觉状态从正常到严重失明，VF和QOL的总得分中位数分别从92降至2，从100降至19。手术组在视觉状态和VF/QOL得分上也有类似发现。手术组VF和QOL的总体得分分别为40和56，未手术组为56和72。通过多变量回归模型调整视觉状态、年龄、性别和教育程度的混杂效应后，未手术组和手术组的QOL得分差异有统计学意义（P = 0.015），而VF得分差异无统计学意义（P = 0.199）。
VF和QOL得分与视觉状态显著相关。该目标人群白内障手术后主观视觉功能和生活质量未得到显著改善。术后随访、无晶状体矫正和社会心理康复应受到关注。
