IRCT201103116032N1 IRCT 2011-06-01 Ahwaz Jondishapour University Of Medicine Science The evaluation of aphakic iris claw intraocular lens implantation results Outcomes of primary iris claw intraocular lens implantation for correction aphakia in comparison with scleral fixation intraocular lens implantation during pars plana deep vitrectomy 2009-09-23 anticipated 25 Complete https://irct.ir/trial/6495 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Single, Purpose: Treatment. N/A Aphakia. The ARTISAN aphakia IOL is a polymethyl methacrylate IOL with an 8.5-mm length, and a 5.5-mm optical zone. In one group patients, initialy a standard 3-port Pars Plana vitrectomy were performed. Crystalline lens or fragment of nucleus that dropped into vitreous extracted by phacofragmentation. Dislocated IOL in vitreous extracted from limbal incision. Then acetylcholine 1% was injected to constrict the pupil and from limbal incision an Artisan IOL was inserted in the anterior chamber. The iris was hooked between the claw-like footplates to achieve perfect IOL centration over the pupil. Finally, the incision was closed with 10–0 nylon sutures. Control group patients were selected retrospectively, from patients that undergo pars plana vitrectomy and sclera fixation Posterior Chamber IOL implantation in past..
