Abstract
Purpose: :
To determine the incidence of cystoid macular edema (CME) following repositioning and McCannel iris suturing of dislocated intraocular lenses.
Methods: :
A retrospective chart review of 28 patients (30 eyes) presenting with lens dislocation who underwent iris-fixation of a PCIOL using McCannel suture technique between December 2008 and August 2011 by a single surgeon (KJW). Incidence of CME and best corrected visual acuity (BCVA) were the main outcome measures. Presence of CME was determined by spectral domain optical coherence tomography (OCT) (Zeiss, Cirrus HD OCT).
Results: :
Of the 30 cases reviewed, 93% had previous cataract extraction with a mean of 5.7 years elapsed (range 1 week to 20 years). Etiology of lens dislocation included: trauma (n=7, 23%), zonular incompetence (n=7, 23%), associated with recent intraocular surgery (n=7, 23%), or unknown (n=9, 30%). Mean best corrected logMAR visual acuity improved from 0.79 preoperatively to 0.44 postoperatively (p = 0.015), with a mean follow-up time of 7.4 months. Two cases (6.7%) of CME occurred postoperatively at a mean follow up time of 4.5 months. Of these two patients, one had concurrent fragmetome lensectomy. Both patients showed subsequent improvement in CME on topical nonsteroidal anti-inflammatory drugs and topical corticosteroid therapy.
Conclusions: :
Iris-fixation of PCIOLs in this case series resulted in an improvement in visual acuity with a low incidence of CME.
