本研究的目的是确定日本老年队列中既往白内障手术和最佳矫正视力（BCVA）的存在。藤原京眼科研究是一项前瞻性、基于人群的横断面流行病学研究。受试者年龄≥68岁，居住在奈良县，对招募通知有反应。所有受试者均接受了全面的眼科检查，并通过问卷调查获得了社会人口学信息和病史，包括既往白内障手术。确定BCVA、年龄、性别和白内障手术史之间的关系。研究对象共2,873名，平均年龄为76.3±4.9（平均±标准差）岁。平均BCVA为最小分辨单位角的- 0.020±0.14对数，教育年限≥13年组BCVA明显优于教育年限≥13年组（p < 0.01）。总体而言，24.2%的受试者接受过白内障手术，年龄≥80岁的受试者中有41.7%接受过白内障手术。既往白内障手术发生率随年龄增加而增加（趋势p < 0.001）。年龄≥80岁白内障手术眼的平均BCVA明显优于未手术眼（p < 0.01）。这组日本老年受试者的视力普遍较好。在本队列中，24.2%的受试者接受过白内障手术，年龄≥80岁的受试者BCVA优于未接受白内障手术的受试者。
The aim of this study was to determine the presence of prior cataract surgery and best-corrected visual acuity (BCVA) in an elderly Japanese cohort. The Fujiwara-kyo Eye Study was a prospective, population-based, cross-sectional epidemiological study. The subjects were ≥68 years who lived in the Nara Prefecture and responded to recruitment notices. All of the subjects underwent comprehensive ophthalmological examinations, and the sociodemographic information and medical history, including prior cataract surgery, were obtained by answers to a questionnaire. The associations between the BCVA, age, sex, and history of cataract surgery were determined. A total of 2,873 subjects whose mean age was 76.3 ± 4.9 (mean ± standard deviation) years were studied. The mean BCVA was −0.020 ± 0.14 logarithm of the minimum angle of resolution units, and it was significantly better in the group with education ≥13 years (p < 0.01). Overall, 24.2% of the subjects had undergone cataract surgery, and 41.7% of the subjects ≥80 years had undergone cataract surgery. The incidence of prior cataract surgery increased with increasing age (p < 0.001 for trend). The mean BCVA of eyes with cataract surgery was significantly better than that of eyes without cataract surgery in subjects ≥80 years (p < 0.01). Visual acuity was generally good in this cohort of elderly Japanese subjects. In this cohort, 24.2% of the subjects had undergone cataract surgery, and the subjects ≥80 years had better BCVA than those without cataract surgery.
