Background.The sutured scleral-fixated posterior chamber lens is a technique often used for the treatment of eyes with or without poor capsular support. Objectives. To analyze the postoperative complication profile. Methods. The postoperative complications of all patients with standardized sutured scleral fixation of a posterior chamber lens were analyzed. We registered clinically important complications with as well as without risk for permanent visual acuity. Results. We analyzed 338 patients (women: 47.3 %; men: 52.7 %). The median postoperative control period was 60 days (min: 1 day, max: 5833 day). 68 % of the patients had at least one complication. The most often registered complications were a postoperative reduction of the internal eye pressure to ≤10 mmHg (3 5% of the patients; n=119), pupil decentration (28 %; n=93), iris capture (5 %; n=17), hemorrhage of anterior chamber, iris or vitreous body (10 %; n=34) and glaucoma (9 %; n=32). Complications with a permanent risk for visual acuity (choroid hemorrhage, retinal detachment) occurred in 3 % (n=10), no endophthalmitis were documented. 51 % (n=212) of all complications happend within the first 7 days. The best corrected visual acuity initially showed a value of 0.97 (logMAR), at the first postoperative control (until 60 days after operation) 1.04 (n=314) and after two years 0.79 (n=43). The postoperative astigmatism increases within the first six months on average by 0.93 dpt, within 12 months by 0.3 dpt. Conclusion. Statistically the patients in our study showed less complications than described in literature. The visual acuity improved less than expected.
