A survey was carried out to examine variation in preoperative testing of healthy patients scheduled to undergo cataract surgery in Canada. The results showed significant variations in which investigations are mandatory and in how close to the time of surgery the tests had to be done. A literature review questioning the value of routine preoperative testing is presented. Eliminating low-yield pre-operative screening tests is a safe way to reduce expenditures on cataract surgery without compromising patient care.
一项调查旨在研究加拿大计划接受白内障手术的健康患者术前检查的差异。结果显示，在哪些检查是必需的以及检查必须在手术前多近的时间进行方面存在显著差异。本文还进行了文献综述，对常规术前检查的价值提出质疑。消除低收益的术前筛查检查是一种安全的方法，可以在不影响患者护理的情况下减少白内障手术的费用。
