title: Clinical comparison of ciliary sulcus and pars plana locations for posterior chamber intraocular lens transscleral fixation.
abstract: OBJECTIVE
  To compare the clinical outcomes of transscleral fixation of a posterior chamber intraocular lens (PC IOL) in the ciliary sulcus or pars plana.
  
  
  METHODS
  Department of Ophthalmology, Seoul National University College of Medicine, Seoul, South Korea.
  
  
  METHODS
  Comparative case series.
  
  
  METHODS
  This retrospective chart review comprised eyes having ciliary sulcus or pars plana fixation of a 3-piece foldable acrylic PC IOL between January 2003 and August 2010. The postoperative corrected distance visual acuity (CDVA), efficacy index, safety index, endothelial cell count (ECC), and complication rates in the 2 groups were compared.
  
  
  RESULTS
  The ciliary sulcus group comprised 38 eyes and the pars plana group, 56 eyes. There was no significant between-group difference in the postoperative CDVA, efficacy index, safety index, or ECC. The mean spherical equivalent difference was larger in the ciliary sulcus group. Intraocular lens dislocation and pupillary capture of the IOL optic occurred more frequently in the ciliary sulcus group (P=.001 and P=.041, respectively). However, retinal detachment, IOL decentration or tilt, cystoid macular edema, secondary glaucoma, and vitreous hemorrhage did not differ significantly between the 2 groups.
  
  
  CONCLUSIONS
  The pars plana location for PC IOL transscleral fixation was as safe and effective as the ciliary sulcus location.
