This Danish multicenter study was undertaken to evaluate current indications for cataract extraction and to compare the heath status among patients enlisted for cataract surgery with that reported for the background population. A consecutive sample of 290 patients from all ophthalmic hospital departments in Denmark was examined and interviewed prior to cataract extraction. The mean visual acuity in the eye enlisted for surgery was 0.17. A visual acuity of < 0.05 occurred in 11.1% and 46.7% had a visual acuity of > or = 0.05 to 0.3. Comparing these figures to other recent European studies it seems reasonable to conclude that in Denmark surgery is performed at an earlier stage of the disease. Only a few patients with no functional impairment were seen; other appropriate indications for surgery were seen for these patients. Occurrence of angina, bronchitis and prior myocardial infarction was higher in the cataract sample as compared to the random sample of Danes. The likelihood of preferring an outpatient procedure was significantly increased among younger patients, patients of better general health and among patients with better pre-operative visual acuity in eye enlisted for surgery.
这项丹麦多中心研究旨在评估白内障摘除的当前适应证，并比较白内障手术患者与背景人群报告的健康状况。在丹麦所有眼科医院科室中，对290例患者进行连续抽样，在白内障摘除术前对其进行检查和访谈。拟手术眼的平均视力为0.17。视力<0.05的患者占11.1%，视力≥0.05至0.3的患者占46.7%。将这些数据与其他近期欧洲研究进行比较，似乎有理由得出结论，在丹麦，手术是在疾病的早期阶段进行的。仅发现少数无功能障碍的患者；这些患者有其他合适的手术适应证。与丹麦人的随机样本相比，白内障样本中心绞痛、支气管炎和既往心肌梗死的发生率更高。在年轻患者、总体健康状况较好的患者以及拟手术眼术前视力较好的患者中，选择门诊手术的可能性显著增加。
