The recently developed acuity card procedure provides rapid assessment of visual acuity in preverbal infants and thus offers the possibility of monitoring the visual development of infants after early surgery for congenital cataract. This report describes our experience with these acuity cards in seven patients with bilateral and seven patients with unilateral congenital cataract. The age at operation was between 1 week and 17 months; visual acuity was assessed up to an age of maximally 2.5 years. In agreement with previous reports, the development of acuity in infants with unilateral aphakia was better if surgery had occurred within the first 6 months of life than at a later time. The results of acuity assessment were generally in good agreement with the clinical signs. The advantages of the acuity cards in clinical use are that: (1) they provide an additional criterion for surgery, including cases of secondary cataract formation; (2) they allow early assessment of the success of the operation; (3) they can be used to judge occlusion therapy; (4) they have proved to be highly motivating for parents to comply conscientiously with the therapeutic measures. Thus, the acuity card procedure has proved to be extremely useful for the assessment of visual development in infants operated on for congenital cataract.
最近开发的视力卡片程序可快速评估不会说话的婴儿的视力，从而为监测先天性白内障早期手术后婴儿的视力发育提供了可能。本报告描述了我们在7例双侧先天性白内障患者和7例单侧先天性白内障患者中使用这些视力卡片的经验。手术年龄在1周至17个月之间；视力评估的最大年龄为2.5岁。与先前的报告一致，单侧无晶状体婴儿如果在出生后的前6个月内进行手术，其视力发育比晚些时候手术更好。视力评估结果与临床体征总体上吻合良好。视力卡片在临床应用中的优点是：（1）它们为手术提供了额外的标准，包括继发性白内障形成的病例；（2）它们可以对手术成功与否进行早期评估；（3）它们可用于判断遮盖疗法；（4）事实证明，它们能极大地激励家长认真遵守治疗措施。因此，视力卡片程序已被证明对评估接受先天性白内障手术的婴儿的视力发育极为有用。
