Abstract Details


The refractive outcome after phakic intraocular lens (PIOL) implantation require sometimes enhancement for optimal results. We evaluated the safety and efficacy of Laser-Assisted Sub-Epithelial Keratectomy (LASEK) in eyes with residual ametropia after phakic IOL (PIOL) implantation.


Refractive surgery Centre


Eyes who required enhancement after PIOL implantation were identified. The preoperative, operation, and postoperative data was abstracted.


Twenty-eight eyes of 21 patients were identified. All eyes underwent LASEK at least 3 months after the implantation of PIOL. The PIOLs included ICL (n=6), Artisan (n=15), toric Artisan (n=2), and Ariflex (n=5). Pre-PIOL the sphere was between -30D to +15.25D, and astigmatism -0.5D to -3.5D. Prior to the laser enhancement, the mean sphere was 0.62D (-5.50 D to +2.00D) and the mean refractive astigmatism was -1.54D (-0.5D to -3.25D). On the last postoperative follow-up visit the mean sphere was +0.110.39D and the mean spherical equivalent was +0.060.42. The mean uncorrected visual acuity was 0.690.16 (decimals) and the best corrected visual acuity was 0.75 0.14, while the safety index was 1 and the efficacy index was 0.93.


LASEK is a safe and effective procedure to correct residual ametropia after PIOL implantation.It may serve as a viable option to enhance the refractive results in patients with previous high refractive errors who didn't reach the target refraction after PIOL implantation.
