Abstract
PURPOSE
The purpose of this study is to document clinical outcomes of 2 posterior chamber phakic intraocular lenses with a central hole, the implantable contact lens (IPCL V2.0) and the Visian implantable collamer lens V4c (ICL), in myopic and myopic-astigmatic patients.
METHODS
Retrospective study comprising 111 IPCL (60 toric) and 106 ICL implantations (59 toric) with a follow-up of 3 months to 2 years. Primary outcome was uncorrected distance visual acuity (UDVA) improvement; secondary outcomes were changes in corrected distance visual acuity (CDVA), and complications.
RESULTS
At 3 months postoperatively, 76% of plano targeted eyes in the IPCL group and 83% of eyes in the ICL group had a UDVA of 20/20 or better. Ninety-six percent of IPCL implanted eyes and 94% of ICL implanted eyes had a postoperative UDVA within 1 line of preoperative CDVA. One eye lost one line of CDVA after IPCL implantation, and no lines were lost after ICL implantation; 33.7% of IPCL eyes and 40.6% of ICL eyes gained at least 1 line of CDVA. Cataract extraction (none because of anterior subcapsular opacification) was performed after 4 ICL implantations, none after IPCL implantation. Endothelial cell loss was mild with both pIOLs. Mean IOP was not clinically significantly affected at 3 months or thereafter.
CONCLUSIONS
We observed equally excellent (statistically not different) results with the IPCL and ICL for the correction of myopia and myopic astigmatism, at least up to 2 years post implantation. Longer follow-up is needed to determine the stability of these results especially with the IPCL.
