Flat anterior chamber (AC) after cataract extraction was found in 7.58% of 8,533 cataract surgeries performed at the Illinois Eye and Ear Infirmary from 1959 to 1970. Of all the aphakic flat ACs, 77.8% reformed spontaneously while receiving medical therapies such as pressure dressing, topical mydriatics, topical mydriatics-miotics intermittently, oral acetazolamide or oral osmotic agents. Of all aphakic flat ACs, 22.2% required surgical repair. Surgically treated flat AC included aphakic flat AC associated with iris prolapse. Of all surgically repaired aphakic flat AC, the distribution of the procedures performed was (1) posterior sclerotomy and air injection 56%; (2) iridectomy for pupillary block 23%; (3) other procedures, mainly anterior vitriotomy, 21%.
