[ Comparison of complications after intra- and extracapsular cataract extraction with lens implantation . Results of a prospective , randomized , clinical study ] . BACKGROUND The postoperative complications of ICCE with ACL implantation are compared with those of ECCE and PCL . Our clinical experience with ICCE and ACL implantation can not confirm the widespread rejection of this method . PATIENTS AND METHOD A prospective , randomized , clinical study with participation of medical statisticians was performed . A total of 190 patients with ICCE and ACL and 170 patients with ECCE and PCL were followed up for 2 years . The follow-up examinations were performed upon dismission from the hospital , after 6 , 12 and 24 months . The data were compiled in a computer program designed for this study and evaluated by the statisticians . The surgical procedures and the surgeons were defined prior to the beginning of patient recruitment . RESULTS ICCE with ACL shows much less postoperative complications as usually emphasized . There were only 2 ( 1.2 % ) of retinal detachment and no case of corneal decompensation . Cystoid macular edema 8 ( 4.7 % ) , postoperative vitreous prolaps into the anterior chamber 4 ( 2.3 % ) and spontaneous complaints of pain 16 ( 9.4 % ) occurred in a low percentage after ICCE with ACL . These complications did not occur after ECCE with PCL . The patients with ECCE and PCL showed capsular fibrosis in 48 ( 28 % ) making it the most frequent complication of the whole study . 33 % of these patients required YAG-laser capsulotomy . Since retinal detachment occurs in 2.5 % after YAG-laser capsulotomy we can not regard capsular fibrosis as a totally harmless complication . It is noteworthy that visual acuity is almost identical 1 year after surgery in both methods . CONCLUSIONS The results of this study show that the evaluation of ICCE with ACL is too negative . The elimination of postoperative complications in this method is more difficult . ECCE with PCL is burdened by frequent capsular fibrosis . Visual acuity is almost the same in both methods 1 years after the operation . ACL-implantation remains our method of choice for secondary implantation in patients with an intact iris diaphragm .
