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

Condition
Aphakia

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Retrospective
Official Title: Intraocular Architecture of Secondary Implanted Anterior Chamber Iris-Fixated Lenses in Aphakic Eyes Evaluated With Anterior Segment Optical Coherence Tomography

Further study details as provided by Michael Koss, Johann Wolfgang Goethe University Hospitals:

Primary Outcome Measures:
  • Intraocular IOL position [ Time Frame: 12-35 months postoperatively ]

Enrollment: 16
Study Start Date: September 2006
Study Completion Date: June 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)
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).
