[The relationship between diabetic retinopathy and cataract extraction with intraocular lens implantation in diabetics].

47 diabetics (71 eyes) having undergone cataract extraction with intraocular lens (IOL) implantation were examined and followed up. The results show that there is significant difference in the last post-operative visual acuities between the diabetic group and non-diabetic group (P < 0.01). The main cause affecting the post-operative visual acuities of the diabetics is diabetic proliferative retinopathy (P < 0.001). There is no significant difference in the post-operative visual acuities between diabetic group with or without simple diabetic retinopathy and non-diabetic group (P > 0.05). The intra- and post-operative complications in the diabetic and non-diabetic group were also investigated and there was no significant difference. IOL implantation should be guarded for diabetics with proliferative retinopathy especially when complicated with maculopathy.
