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.
Highlights
Most of patients are hoping to see well without spectacle or contact lenses
In last years the refractive surgery increased in patients dissatisfied with spectacles and contact lenses either due to quality of vision, cosmetic appearance or difficulties in contact lenses wearing and its complications. corneal surgeries like corneal ablation ( photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis Laser Insitu Keratomeleiosis (LASIK)) and different types of phakic intraocular lens (PIOL) implantation either in the anterior or posterior chamber and the anterior chamber either iris claw or angle fixation intraocular Lens (IOL) aim to correct s refractive errors in myopic patients [1,2]
Artiflex or Veriflex PIOL for correction of myopia was implanted in patients unsuitable for LASIK due to thin cornea, abnormal pentacam or refraction out of range of correction.This study were done between March 2010 and March 2012, in a retrospective study
Summary
Corneal surgeries like corneal ablation ( photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis LASIK) and different types of phakic intraocular lens (PIOL) implantation either in the anterior or posterior chamber and the anterior chamber either iris claw or angle fixation IOL aim to correct s refractive errors in myopic patients [1,2]. Corneal surgeries, such as photorefractive keratectomy (PRK) and LASIK, have many limitations and contraindications especially for the correction of high refractive errors. Due to these limitations and complications, indications for corneal refractive surgery have narrowed [3,4,5,6]
