Iris-claw intraocular lens implantation after pupil reconstruction in 8 patients with iris rupture

Abstract

Objective To observe the anatomic and functional recovery of Iris-claw intraocular lens (IOL) implantation after iris and pupil reconstruction in traumatic cataract eyes with ruptured iris or dilated pupil.Methods This retrospective case series included 8 eyes of 8 patients with iris and pupil reconstruction combined with iris-claw IOL implantation from May 2010 to August 2011 in the Affiliated Eye Hospital of Wenzhou Medical College.Three were eye blunt injury,5 were penetrating ocular trauma.All patients were diagnosed traumatic cataract,including 3 patients with lens dislocation.Primary outcome measurements included visual acuity,central endothelium cell count,pupil situation,position of IOL,intraocular pressure,etc.Results IOL were implanted and their irises/pupils were repaired successfully.With 4-11 months following up,visual acuity in all of 8 cases was better or equal to the preoperative predictable vision.There were 6 eyes (75％) with the best visual acuity no less than 0.6.Photophobia,dazzling sensation and other symptoms disappeared.No complications of iris-claw IOL dislocation,high intraocular pressure,or corneal decompensation happened in the 8 cases.Conclusions Iris and pupil reconstruction combined with iris-claw IOL implantation is a safe and efficacious option for traumatic cataract eyes with absence of capsule support and ruptured iris or dilated pupil.
