A total of 55 cataract extractions were performed on 53 patients aged 90 years or more in the period 1972 to 1982. Assessment of the outcome was based on data from hospital records and on questionnaires to the patient's ophthalmologist and general practitioner. Cataract surgery had improved visual acuity in 42 patients. Only 25 patients (47%) could, however, utilize the improved visual acuity, and obtain some practical benefit from the cataract extraction. Thus, the benefits of cataract surgery seem to be reduced in this age group. The reasons appear to be a high frequency of severe macula degeneration, some degree of senility hindering the adaptation to aphakic spectacles, and a somewhat higher frequency of per- and post-operative complications. This suggests that indications for cataract surgery in very old patients should be limited, at least if rehabilitation with aphakic spectacles is planned. An earlier surgical intervention would probably have been advantageous in the majority of these patients.
1972年至1982年期间，对53名90岁及以上的患者进行了共计55次白内障摘除手术。疗效评估基于医院记录数据以及向患者的眼科医生和全科医生发放的调查问卷。白内障手术使42名患者的视力得到改善。然而，只有25名患者（47%）能够利用改善后的视力，并从白内障摘除术中获得一些实际益处。因此，在这个年龄组中，白内障手术的益处似乎有所减少。原因似乎是严重黄斑变性的发生率较高、一定程度的衰老阻碍了对无晶状体眼镜的适应，以及手术前后并发症的发生率略高。这表明，至少在计划使用无晶状体眼镜进行康复治疗的情况下，老年患者白内障手术的适应症应受到限制。对这些患者中的大多数人来说，更早进行手术干预可能会更有利。
