Comparison between Foldable and Hard [PMMA] Iris Claw Phakic Intraocular Lens Implantation for Correction of High Myopia

Background:Iris claw phakic intraocular lens [PIOL] is one of the surgical techniques used for the correction of high myopia. This procedure reduces myopia with stable refractive results and preserves the accommodation. Aim of the Work:The aim of this study is to assess the outcome of foldable and hard [PMMA] iris claw PIOL implantation as one of surgical procedures in the management of high myopic young patients. Patients and Methods:A prospective comparative study having foldable and hard [PMMA] iris claw phakic intraocular lens [PIOL] for correction of high myopia. This study includes forty eyes [40 eyes] of twenty high myopic patients [20 pt.] with refraction range of [-10.0 D to -25.0 D] without or with cylinder not more than [-2.0 D]. The patients were divided to two groups [A] and [B], each group contains twenty [20] eyes, the first 20 eyes [group A] received a concave-convex foldable iris claw PIOL and the remaining 20 eyes [group B] received a biconcave optic hard PMMA iris claw PIOL. Result:The mean postoperative SE at 6 months in group [A] was [-0.30 ± 0.10 D] within ±1.00 D of emmetropia. In group [B] it was [- 0.50 ± 0.50 D] within ±1.0 D of emmetropia. The mean postoperative cylinder at 6 months was [-0.31 ± 0.10] in group [A], and [-0.51 ± 0.51] in group [B]. There was a statistically significant difference between preoperative UCVA and postoperative UCVA at 6 months were [p
