The authors evaluate results of secondary implantation of open-loop, flexible, anterior chamber intraocular lenses (IOLs) in the group of 94 patients (94 eyes), operated on at the Department of Ophthalmology, University Hospital, Hradec Králové from September 1995 to September 1996. There were 54 women (58.8%) and 40 men (41.2%). Patient age ranged from 27 to 89 years (mean 70.1 years). Operations were performed by 5 surgeons using local anesthesia. Early postoperative complications were corneal edema in 2 cases (2.2%), hyphaemia in 2 cases (2.2%) and higher intraocular pressure in 1 eye (1.1%). For the control analysis 68 patients were available. Late complications included transient pressure elevation in 11 eyes (16.2%), iris capture syndrome in 1 eye (1.4%) and ulcus corneae in 1 eye (1.4%). Final best corrected visual acuity 6/9 and better achieved 31 patients (45.6%). Sixty-one patients (89.9%) were very satisfied or satisfied. On the basis of our findings we recommend open-loop, flexible, anterior chamber IOLs for secondary implantation, when the use of posterior chamber IOLs is not suitable.
