Diplopia as an uncommon complication of cataract surgery

Two patients are presented with diplopia after cataract extraction performed under local anesthesia. Since there was no spontaneous recuperation after several months, strabismus surgery was performed. The first patient presented a restriction of the inferior rectus muscle probably caused by the retrobulbar injection of anesthetics. The second patient had a decompensation of a congenital superior oblique palsy. A survey of the different etiologies of diplopia after cataract surgery is given.
