Background. Implantation of sutureless, scleral-fixated posterior chamber intraocular lenses (SSFIOL) is a promising option in the surgical management of patients unable to undergo standard cataract surgery due to insufficient capsular support. The purpose of this study was to describe the indications, visual outcomes and complications of SSFIOL implantation.Methods. Retrospective, investigational cohort study of 112 consecutive SSFIOL implantations between July 2013 and August 2017. Pre-operative ocular morbidity, operative indications, postoperative outcomes, complications, and reinterventions were summarized. Visual and refractive outcomes were compared between the pre- and latest postoperative visit using Wilcoxon signed-ranked test.Results. Mean follow-up: 13.0 ± 10.4 months. Primary surgical indication was dislocated IOL due to zonular weakness (77 eyes (68.8%)). At latest follow-up, there was improvement in uncorrected visual acuity (1.3 ± 0.8 to 0.64 ± 0.60 logMAR, p 30 mmHg (26.8%), cystoid macular edema (CME) (14.3%), transient hypotony (13.4%), iris capture (12.5%), uveitis-glaucoma-hyphema (UGH) syndrome (11.6%), vitreous hemorrhage (VH) (6.3%). Operative reinterventions included SSFIOL exchange (3.6%), SSFIOL repositioning (5.4%), SSFIOL removal (2.7%). Ten (8.9%) patients required multiple re-interventions.Conclusion. SSFIOL implantation is a reasonable option for eyes with inadequate capsular support, resulting in visual improvement in most patients. Many of the surgical complications were related to a floppy iris-lens diaphragm (UGH syndrome, iris capture), which were predisposed in eyes with complex pathology. Surgical modifications can be made to minimize the iris-related complications.
