Abstract
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 <0.001] in both groups. Postoperative BCVA [logMar] at 6 months was 0.11 ± 0.14 in group [A] and 0.27 ± 0.17 in group [B].
Conclusion: iris-claw phakic IOL implantation is frequently used for highly myopic cases. Compared to corneal refractive surgery, phakic IOLs favorably compete for the correction of high myopia, with increasing predictability, efficacy, safety, and quality of vision.
