title: Incidence of cystoid macular edema with iris-fixated posterior chamber intraocular lenses in patients presenting with lens dislocation.
abstract: The aim of this study is to determine the incidence of cystoid macular edema (CME) following repositioning and McCannel iris-suturing of dislocated intraocular lenses. This study is conducted in an urban private practice. A retrospective chart review was performed on consecutive patients who presented with posteriorly dislocated IOLs and underwent iris-sutured posterior chamber (PC) intraocular lens (IOL) placement using the McCannel suture technique by a single surgeon for IOL repositioning from December 2008 to August 2012. All charts were reviewed for etiology of dislocation, time elapsed from cataract surgery, best-corrected visual acuity (BCVA), slit-lamp examination, tonometry, and dilated fundus examination. Presence of CME was determined by spectral domain optical coherence tomography (Cirrus HD OCT; Carl Zeiss Meditec, Dublin, California, USA). Of the 58 cases reviewed, lens dislocation resulted from trauma in 21 %, zonular incompetence in 17 %, recent intraocular surgery in 12 %, and unknown in 50 %. Mean best-corrected logMAR visual acuity improved from 1.07 preoperatively to 0.52 postoperatively (P < 0.001). The mean follow-up time was 7.8 months. Two cases (3.4 %) of CME occurred postoperatively at a mean follow-up time of 4.5 months. Of these two patients, one had concurrent fragmetome lensectomy at the time of initial surgery. Iris-sutured PC IOL placement in this case series resulted in an improvement in BCVA with a low incidence of CME.
