Intraocular Position of Secondary Iris-Fixated IOLs in Aphakic Eyes

September 26, 2012 updated by: Michael Koss, Johann Wolfgang Goethe University Hospital

Intraocular Architecture of Secondary Implanted Anterior Chamber Iris-Fixated Lenses in Aphakic Eyes Evaluated With Anterior Segment Optical Coherence Tomography

The purpose of this study is to evaluate the intraocular stability and safety of secondary iris-fixated IOLs in aphakic patients.

Conditions

Detailed Description

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).
