Iris Claw versus Scleral Fixation Intraocular Lens Implantation during Pars Plana Vitrectomy.

Purpose: To compare the outcomes of iris claw anterior chamber intraocular lens (IC-ACIOL) with that of scleral fixation posterior chamber intraocular lens (SF-PCIOL) implantation during pars plana vitrectomy (PPV) as initial surgery to correct aphakia.

Methods: Twelve patients with complicated cataract surgery or trauma who hadsuffered nucleus, whole crystalline lens or intraocular lens (IOL) drop into the vitreous cavity, and undergone PPV with IC-ACIOL implantation over a period of one year were evaluated for the purpose of this study. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), central corneal thickness (CCT), spherical equivalent (SE) refractive error, astigmatism and complications were recorded.
