[Comparative study of postoperative complications in primary and secondary implantation of posterior chamber intraocular lens in cataract surgery for diabetic patients].
Postoperative complications of diabetic cataract cases with active stage diabetic retinopathy, which underwent simultaneous extracapsular lens extraction (ECCE) and posterior chamber intraocular lens (PC-IOL) implantation in 84 eyes, ECCE only in 38 eyes and secondary implantation of PC-IOL after ECCE in 23 eyes, were studied. In the eyes of the primary PC-IOL implantation group, fibrous response in 35 eyes (42%), posterior iris synechia in 10 eyes (12%), progression of diabetic retinopathy in 13 eyes (16%), after cataract in 11 eyes (13%), pupil capture in 4 eyes (5%) and decentration of lens optics in 3 eyes (4%) were appeared, while in the ECCE only group, fibrous response in 11 eyes (29%), posterior iris synechia in 4 eyes (11%), after cataract in 11 eyes (29%), progression of diabetic retinopathy in 6 eyes (16%) were observed. On the other hand, in the secondary PC-IOL implantation group, only fibrous response was appeared in 1 eye (4%), Although PC-IOL implantation has been so far considered contraindication in cases with cataract combined with active stage retinopathy, the present studies strongly suggest that secondary PC-IOL implantation would be good indication in these cases whose blood sugar was properly controlled and the retinopathy was burned out by panretinal photocoagulation soon after ECCE.
