[Laser coagulation of the retina in patients with diabetes after posterior-chamber lens implantation].

The possibility of laser coagulation of the retina after implantation of posterior-chamber lenses was examined in 44 patients with diabetes mellitus. Three-speculum Goldman's lens could be used to examine the central zone in 40 patients, the median periphery in 36 patients, and the utmost periphery in 6 patients. The principal causes impeding the examination of the retina were (1) posterior capsule opacity, (2) inadequate mydriasis because of synechias between the iris and the intraocular lens. The number of patients in whom the fundus oculi could be examined was reducing with time. Mydriasis of 8 mm was found necessary for the examination of the total fundus oculi of the artiphakic eye.
