Diabetes mellitus and intraocular lens implantation.
Prospective evaluation of extracapsular cataract extraction with posterior chamber intraocular lens (ECCE-posterior chamber IOL) in 234 eyes of 20 diabetics, with and without nonproliferative retinopathy, and 209 nondiabetics demonstrated no statistically significant difference in operative or postoperative complications. A postoperative final visual acuity of 20/40 or better was achieved in 65% of diabetic surgical eyes and in 90% of nondiabetic surgical eyes, a difference that was statistically significant (P = 0.0049). When eyes with diabetic retinopathy or other pre-existing ophthalmic disease responsible for decreased vision were excluded, postoperative visual acuity of 20/40 or better was obtained in 93% of diabetic eyes and 96% of nondiabetic eyes, a difference that was not statistically significant (P = 0.5045). Therefore, the relatively less favorable outcome of ECCE-posterior chamber IOL surgery in diabetics, with or without nonproliferative retinopathy, is due to greater frequency of retinopathy or other ophthalmic disease responsible for decreased vision. Based on this study and all available information, guidelines regarding diabetes mellitus and intraocular lens implantation are presented.
