Anterior Chamber Foldable Phakic Intra Ocular Lens Safety and Efficacy

Abstract

Purpose: Correction of myopia by implantation of intra ocular lens is a growing surgery. In this study I am trying to assess the visual outcome stability and safety of eyes undergoing Anterior chamber foldable phakic lens implantation (Artiflex) (Ophtec BV, Groningen, The Netherlands) or (veriflex) (AMO,Santa Ana,CA) for myopia unsuitable for LASIK and detection of early and late complications along three years follow up period.Methods: A retrospective analysis of 25 eyes of 16 patients underwent Anterior chamber foldable phakic IOL (Artiflex) or (Veriflex) implantation for correction of myopia all patients were unsuitable for LASIK all patients underwent surgery with one surgeon in same circumstances. Uncorrected visual acuity, corrected visual acuity (BCVA), higher-order aberrations, patient satisfaction, central endothelial cell count, and PIOL position centration and incarcerated iris tissue were determined along follow up period. Results:At the end of the 36 months of follow up period 14 of the 25 eyes (56 %) achieved BCVA better than that measured pre-operatively and 10 of the 25 eyes (40%) matched their pre-operative BCVA. One eye (4 %) attained a final BCVA worse than pre-operatively, due to recurrent uveitis. One patient (4%) need another surgery to fixate the lens due to slippage of incarcerated iris tissue with impending displacement. Conclusions:This study suggests that Anterior chamber foldable phakic IOL (iris claw lens insertion) Artiflex or Veriflex is beneficial in myopia, unsuitable for LASIK, matching or exceeding preoperative BCVA in the overwhelming majority of the cases. With no major complications however long standing follow up is needed to avoid major complications. Citation
