The authors presented long-term results of surgery of congenital, residual, traumatic and post-inflammatory cataracts. Lensectomy through pars plana was performed in all eyes. Examination after 12-year follow-up was performed in 186 eyes, i.e.-69.4% of the total number of 268 eyes which underwent surgery. The most frequent complication was glaucoma (33.3%), which passed without any symptoms and was diagnosed accidentally, in the majority of cases in the period over 3 years after surgery. Other complications were rare; They included retinal detachment in 0.5% of the eyes. Visual acuity was 5/50 and less in 52.7% of the eyes; only in 10% it was 5/10 and better. The conclusion is that all patients after cataract surgery should be examined for glaucoma.
