Data collected by clinicians and nurses from patients with clinically diagnosed lens opacities revealed that there was poor repeatability of the description of the position of lens opacities, statistically significant observer variation in determining visual acuity, and good repeatability as to what visual tasks the patient can perform. It is suggested that clinicans should give more weight to the visual handicap revealed by performance of visual tasks in making a decision for cataract surgery than at present.
临床医生和护士从临床诊断为晶状体混浊的患者那里收集的数据显示,晶状体混浊位置的描述重复性差,在确定视力方面存在具有统计学意义的观察者差异,而患者能够执行哪些视觉任务的重复性良好。建议临床医生在决定是否进行白内障手术时,应比目前更加重视视觉任务表现所揭示的视觉障碍。
