The purpose of this study is to evaluate the intraocular stability and safety of secondary iris-fixated IOLs in aphakic patients.
Condition or disease
18 eyes of 16 patients received secondary anteriorly iris-fixated intraocular lenses (IOLs) to correct for aphakia without capsular support, partly combined with anterior or complete pars plana vitrectomy. Primary outcome measurements included visual acuity (6m Snellen charts), central endothelium cell count (cECC) and postoperative intraocular position of the IOL assessed with anterior segment optical coherence tomography (OCT).

Ages Eligible for Study:
16 Years to 84 Years (Child, Adult, Senior)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Patients with long standing Aphakia and eligibility for secondary IOL implantantion were retrospectively examined
Patients with aphakia due to complicated cataract surgery, weakness in lens support (capsula, zonulae) Marfans´s syndrome
Aphakia due to preexisting corneal, retinal o uveal disease, low endothelial cell count
