To investigate the long-term characteristics of cataracts among adults aged 30 to 49 years in Korean over a span of 10 years.
Subjects between the ages of 30 to 49 years who underwent cataract surgery at St. Mary's Hospital from 1995 to 2004 (n = 976) were included. Patients with a history of ocular trauma, uveitis, other ocular or systemic diseases, and congenital cataracts were excluded. Additional information including type of lens opacity, urban/rural region, and pre- and postoperative visual acuities were analyzed. Lens opacity grading was conducted using Lens Opacity Classification System III. The Cochran-Armitage proportion trend test was used to analyze vision changes with the passage of time.
Among the patients who had undergone cataract surgeries, 8.8% (976 / 11,111) met the inclusion criteria. The mean age was 41.7 ± 5.45 years. Gender breakdown of the patient population included 79.0% male and 21.0% female. In terms of home environment, 60.9% were from an urban region and 39.1% from a rural region. Opacity type included anterior polar (AP), posterior subcapsular (PSC), AP and PSC, cortical, and nuclear in 35.7%, 35.1%, 7.0%, 6.0%, and 5.4% of patients, respectively. At a 2-month postoperative follow-up appointment, 92.7% of patients showed a best-corrected visual acuity of more than 20 / 40.
Predominance of AP and PSC opacities as well as male patients was observed in this study population.
调查10年间韩国30至49岁成年人白内障的长期特征。
纳入1995年至2004年在圣玛丽医院接受白内障手术的30至49岁患者（n = 976）。排除有眼外伤、葡萄膜炎、其他眼部或全身疾病以及先天性白内障病史的患者。分析包括晶状体混浊类型、城乡地区以及术前和术后视力等附加信息。使用晶状体混浊分类系统III进行晶状体混浊分级。采用 Cochr an-Armitage比例趋势检验分析视力随时间的变化。
在接受白内障手术的患者中，8.8%（976 / 11,111）符合纳入标准。平均年龄为41.7 ± 5.45岁。患者人群的性别分布为男性79.0%，女性21.0%。就家庭环境而言，60.9%来自城市地区，39.1%来自农村地区。混浊类型包括前极性（AP）、后囊下（PSC）、AP和PSC、皮质性和核性，分别占患者的35.7%、35.1%、7.0%、6.0%和5.4%。术后2个月随访时，92.7%的患者最佳矫正视力超过20 / 40。
本研究人群中观察到AP和PSC混浊以及男性患者占优势。
