[The effect of neurohumoral factors of the sympathoadrenal system on the results of cataract extraction with intraocular lens implantation in diabetic patients].

Effect of the sympathoadrenal system (SAS) on the results of cataract extraction with IOL implantation was studied by analyzing the stress index in 64 patients with diabetes mellitus and 20 reference patients. SAS reaction to surgical stress was abnormal in 34 (53.1%) diabetics. The level of SAS activity, postoperative complications, and kinetics of regenerative repair processes in the cornea were related. In 15 (23.%) diabetics with a low stress index the postoperative period was characterized by frequent inflammations, longer repair of normal corneal homeostasis, and coarse cicatrization. In 19 (29.7%) diabetics with a high stress index after cataract extraction normalization of the corneal homeostatic parameters was delayed and macular edema developed 4.8 times more often.
