摘要
目的 了解安徽省2013-2014年度贫困白内障患者复明术后中远期恢复情况.方法 横断面调查研究.采用整体随机抽样方法抽取8个受检点（舒城县、庐江县、潜山县、池州市贵池区、郎溪县、太和县、亳州市谯城区、灵璧县）调查1 140例（1 557眼）白内障术后患者,所有受检人员均接受详细眼科检查,包括视力、裂隙灯显微镜、直接检眼镜、眼压和验光等.结果 共718例（985眼）完成检查,受检率为83.0％.术后最佳矫正视力（BCVA） ≥0.05者940眼（95.4％）,≥0.3者826眼（83.8％）,≥0.5者670眼（68.0％）.979眼（99.4％）植入人工晶状体（IOL）;963眼（97.8％）角膜透明,904眼（91.8％）瞳孔正圆无移位,953眼（96.8％）IOL居中正位,623眼（63.2％）后囊透明,眼压为（14.3＆#177;4.9）mmHg. 284眼（28.8％）伴屈光不正.主诉最多者为流泪[313眼（31.8％）].BCVA低于0.05的眼中,原因依次为年龄相关性黄斑变性、高度近视性视网膜病变、后发性白内障、角膜斑翳和视神经萎缩等;在BCVA低于0.3的眼中,主要原因依次为年龄相关性黄斑变性、后发性白内障、高度近视性视网膜病变、角膜斑翳和糖尿病视网膜病变等.结论 安徽省80％以上的免费白内障手术患者达到康复视力,约30％的患者伴有屈光不正和后发性白内障,术后低视力和盲的患者主要由术前原有的眼底病变导致.
Objective To investigate the medium-to long-term effects on visual acuity for poverty patients undergoing free cataract surgery from 2013 to 2014 in Anhui Province.Methods In this cross-sectional survey,geographically defined cluster sampling was used to randomly select 1 140 cases in 8 basic sample units （Counties of Shucheng,Lujiang,Qianshan,Langxi,Taihe,and Lingbi,and District Guichi of Chizhou,and District Qiaocheng of Bozhou）.The duration between the investigation and cataract operation was 3 to 21 months.All cases received comprehensive ophthalmologic examination,including visual acuity,slit lamp examination,ophthalmoscopy,intraocular pressure （IOP）,and optometry.Results The investigation included 718 cases （985 eyes） （83.0%）.Best corrected visual acuity （BCVA） was ≥0.05 in 940 eyes （95.4%）,≥0.3 in 826 eyes （83.8%）,and ≥0.5 in 670 eyes （68.0%）.Intraocular lenses （IOLs） were implanted in 979 eyes （99.4%）.The cornea was clear in 963 eyes （97.8%）,and the pupil was intact in 904 eyes （91.8%）.The location of intraocular lens was central in 953 eyes （96.8%）,and the posterior capsule was transparent in 623 eyes （63.2%）.The average IOP was 14.3＆#177;4.9 mmHg.Ametropia was found in 284 eyes （28.8%）.The most common complaint was tearing [313 eyes （31.8%）].Eyes with BCVAs of 〈0.05 had age-related macular degeneration,posterior capsular opacification （PCO）,high myopic retinopathy,corneal opacity,and optic nerve atrophy.Eyes with BCVAs less than 0.3 had age-related macular degeneration,PCO,high myopic retinopathy,corneal opacity,and diabetic retinopathy.Conclusion More than 80% of poverty patients in Anhui Province after free cataract surgery had been recovered to normal vision.The most common complications were residual refractive error and PCO.The major causes of blindness and low vision after cataract surgery were pre-existed retinal diseases.
