ABSTRACT
PURPOSE:
For patient with extreme myopia outside the suspected limit of single procedure alone, we performed Lasik as a secondary procedure for the correction of residual refractive error following phakic IOL implantation.METHODS:
First, we made a corneal flap using ACS(Bauch & Lomb surgical/Chirom vision, Irvine, CA) due to the potential risk of endothelial damage by cornea-IOL contact during the flap dissection. One month later, phakic IOLs, Nuvita MA20 (Bauch & Lomb surgical/Chiron vision, Irvine, CA) implantation were done, and 4 months after IOL implantation, stromal ablation was performed with the eximer laser by using previously formed flap.RESULTS:
Preoperative spherical equivalent refraction was -25.0 D of Rt eye, -24.0 D of Lt eye, and preoperative visual acuity was 20/500 (best spectacle corrected visual acuity; BSCVA 20/50) of Rt eye, 20/200 (BSCVA 20/40) of Lt eye. Spherical equivalent refraction following phakic IOL implantation was -4.25 D of Rt eye, -3.75 D of Lt eye and refractive cylinder was -1.0 D cyl x90 A, visual acuity was 20/100 (BSCVA 20/40) of Rt eye, 20/100 (BSCVA 20/40) of Lt eye. Spherical equivalent refraction at the last examination following LASIK was -0.75 D of Rt eye, -0.5 D of Lt eye and visual acuity was 20/25 (BSCVA 20/25) of Rt eye, 20/25 (BSCVA 20/25) of Lt eye.CONCLUSIONS:
Bioptics by combined anterior chamber phakic intraocular lens and laser in situ keratomileusis is one of the effective methods for patients with refractive error of extreme myopia outside the suspected limits of single procedure alone. Longer follow-up of large number of cases is needed to fully assess the safety and complications.
