Extracapsular cataract extraction with simultaneous implantation of 300 Copeland iris plane lenses: five-year follow-up--a retrospective study.
Three hundred cases of extracapsular cataract extraction with Copeland iris plane lens implantation were reviewed. Two hundred sixty-six patients were followed objectively from 180-1,420 days with a mean follow-up of 1,026 days. 12.4% necessitated secondary operations, most of these being posterior capsulotomies. 89.5% of patients with a mean age of 73.6 years achieved visual acuity of 6/6-6/12. Using an extracapsular cataract extraction with a Copeland iris plane lens, the results obtained were considerably improved over that of intracapsular surgery.  A similar retrospective study of a larger series using extracapsular cataract extraction with the Binkhorst iridocapsular lens is currently being carried out.
