The average time since implantation was 5-5 years aand in 85 per cent. of eyes the corrected visual acuity was 6/12 or better. Bullous keratopathy, corneal epithelial oedema, and peripheral anterior synechiae giving rise to glaucoma were the most serious complications. Visual result, binocular function, and patient satisfaction were generally very good.
