ABSTRACT
A prospective study of the effect of cataract extraction with intraocular lens implantation on the course of diabetic retinopathy (DR) in 44 patients (59 eyes) was carried out. It showed that in the 1-3 years following surgery, there was progression of DR (including development of newly formed retinopathy) in 35% of the patients (28.8% of eyes). Progression was more marked in patients with pre-operative bilateral DR compared to those without bilateral DR (77% and 16% respectively). Insulin dependence did not play a role in progression. Final visual acuity was better in patients without pre-operative DR, as well as in eyes without progressive retinopathy.

A prospective study on the effect of ECCE + IOL implantation on the course of diabetic retinopathy (DR) in 59 eyes showed that in one to three years following surgery, progression of DR, including the development of newly formed one, occurred in 28.8% of the eyes. This was more marked in patient with IDDM (IDDM-46%, NIDDM-24%) as well as in eyes with pre-operative BDR (pre-operative BDR-62.5%, no pre-operative BDR-16.3%). Final visual acuity was better in eyes without pre-operative DR as well as in eyes that did not show progression of the retinopathy.
