[Initial experience with implantation of disc-type intraocular lenses]

The authors present their postoperative results of extracapsular cataract extraction with implanted disc intraocular lens CD 801 A (Pharmacia). In 1991 within 6 months 62 of these lenses had been implanted. A year after the operation, the location of the intraocular lens, transparency of posterior capsule, the shape of the pupil and visual acuity (correction) had been followed. In 6 patients (9.7%) dislocated lenses had been found, 11 patients (17.7%) developed decreased transparency of the posterior capsule, and in 30 patients (48.4%) circular shape of the pupil was in different way distorted. 48 eyes (77.42%) had 1 dioptre error or less, 58 eyes (93.55%) had 2 dioptres error or less and 4 eyes (6.45%) had an error of more than 2 dioptres.
