Seven patients had bilateral intraocular lens implantation performed with a short interval between procedures, using intraocular lenses of unproven design or deficient quality control All seven patients suffered severe visual impairment, some to the level of legal blindness in both eyes. Lenses with unproven design characteristics should never be implanted in both eyes of a patients. The interval between the first and second procedure, even when using lenses of proven design and quality, should be long enough to insure the long-term successful outcome of the first procedure.
7名患者接受了双眼人工晶状体植入手术，两次手术间隔时间很短，所使用的人工晶状体设计未经证实或质量控制存在缺陷。所有7名患者均出现严重视力损害，部分患者双眼达到法定失明程度。设计特征未经证实的晶状体绝不应植入患者双眼。即使使用设计和质量已获证实的晶状体，首次手术和第二次手术之间的间隔时间也应足够长，以确保首次手术取得长期成功结果。
