[Analysis of the first 1000 implants of intraocular lenses]

The authors give an account of the development of implantology and extracapsular extraction in their department. In 1987 they performed 342 operations of cataract, an intraocular lens was implanted in 13.2%, extracapsular extraction was performed in 12.9%. In the first half of 1991 354 operations of cataract were performed, an intraocular lens was implanted in 82.5%, and extracapsular extraction was performed in 96.9%. The most frequent peroperative complication was rupture of the posterior capsule--from 14.0% to 20.1%. The most frequent postoperative complication (306 implantations in the first half of 1991)--keratopathia striata 179, fibrinous exudate--79, elevated intraocular pressure--50. The time spent in hospital in the first half of 1991 was on average 2 days in 156 operated patients who did not develop any or only one postoperative complication. The most frequent postoperative complication was posterior capsule opacification--11%. The most serious late complication during the entire follow-up period was endo-ophthalmitis in 8 eyes which in 5 patients after an interval up to 12 months following operation ended by evisceration of the bulbus--in all instances Russian lenses which were sterilized by ourselves were involved. The visual acuity on admission was below 6/60 in 72.3%, on discharge 6/12 or better in 32.8% and 6 months after operation 6/12 or better in 73.9%, incl. 651 eyes (88%) without supplementary correction. Despite the difficult conditions extracapsular extraction with implantation of an intraocular lens has become a routine method in our department, with a short period of hospitalization and minimal contraindications.
