Clinical Result of Iris Claw Lens and Trans-scleral Fixation Technique of Posterior Chamber Lens

ABSTRACT

Recently, with the development of ophthalmic surgical technique, many of aphakic patients want secondary implantation of intraocular lens. In aphakic eye without posterior capsule, implantation of posterior chamber lens can be performed by sulcus fixation of lens with prolene suture. But sulcus fixation technique has some complications as iP~rmanent fistula, rotation or tilting of the optics, hyphema, endophthalmitis and so on. In this study, 24 aphakic eyes, 22 patients implanted withl itis claw lens were compared with 13 aphakic eyes, 13 patients implanted with sulcus fixated posterior chamber IOLs. In 24 eyes implanted with iris claw lens, 18 eyes (75%) had a postoperative visual acuity of 20/40 or better and cystoid macular edema, intraocular lens dislocation were observed on each 2 eyes (8.3%) and iridodialysis on 1 eye (4.1 %). In 13 eyes implanted with sulcus fixed PCLs, 12 eyes (92%) had a postoperative visual acuity of 20/40 or better, and cystoid macular edema, vitreous hemorrhage, acute iridocyclitis and glaucoma were observed in each 1 case (7.7%). In aphakic eyes without posterior capsular support, iris claw lens will be a alternative method of intraocular lens implantation.
