PURPOSE: To analyze long-term visual outcomes and complications of the implantation of a scleralfixated posterior chamber intraocular lens (PC-IOL) in patients with the lack of adequate capsular support, and to verify if the procedure can be performed with 9-0 polypropylene sutures.
METHODS: The study was designed as a long-term retrospective analysis. Patients after the implantation of a scleralfixated PC-IOL were evaluated for the best corrected visual acuity (BCVA), intraocular pressure and occurrence of postoperative complications.
RESULTS: The analysis included 29 eyes from 28 patients. Indications for the IOL implantation included ocular trauma (89.7%) and previous complicated cataract surgery (10.3%). A postoperative improvement of BCVA was observed in 25 eyes (86.2%). Mean follow-up time was 63.9 months (range 50-83 months). During this time, six patients (21.4%) were diagnosed with glaucoma (21.4%), and retinal detachment was found in one eye (3.4%). A total of six suture breakages were recorded in four eyes from four patients (13.8%); one breakage was precipitated by a trauma, and another five, involving three eyes from three patients, were spontaneous. Mean time to the spontaneous suture breakage was 40.8 months.
CONCLUSIONS: Scleral fixation of the PC-IOL provides satisfactory visual outcomes. However, this procedure is associated with a considerable risk of postoperative complications. The incidence of postoperative suture breakage in our series was similar as in previous studies in which the PC-IOL was fixated with 10-0 polypropylene suture. A superiority of 9-0 polypropylene suture needs to be verified in larger series of consecutive patients.
