So in last years the refractive surgery increased in patients dissatisied with spectacles and contact lenses either due to quality of vision, cosmetic appearance or diiculties in contact lenses wearing and its complications. corneal surgeries like corneal ablation ( photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis LASIK) and diferent types of phakic intraocular lens (PIOL) implantation either in the anterior or posterior chamber and the anterior chamber either iris claw or angle ixation 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. Postoperative ectasia which is a major problem can occur with removing of too much corneal tissue to correct high myopia with the laser. Night bad quality vision and dry eye complaints may be transient or permanent symptoms which may cause dissatisfaction for refractive patients. Due to these limitations and complications, indications for corneal refractive surgery have narrowed [3-6].

Intraocular refractive surgeries may be classiied into: phakic intraocular lens (PIOL) implantation with preservation of crystalline lens and clear lens extraction with lens implantation, also called refractive lens exchange. Clear lens extraction may increases the risk for retinal detachment and is generally not preferable in myopic pre- presbyopic patients who can still accommodate as it deprive them from useful accommodation and always patient sufers from disability of near vision without glasses. Retinal detachment ater refractive lens exchange for high myopia is always present and has been described to occur in 2% to 8% of patients which increase if complications occurred during surgery [9,10]. PIOL implantation in suiTable patients may be more favorable than other refractive surgery techniques, the PIOL is potentially reversible as the PIOL is removable surgically with any major complication. Visual recovery is fast, and accommodation is preserved with great beneit in pre presbyopic patients. Implantation of a PIOL utilizes operative techniques familiar to most anterior segment surgeons and does not require expensive or specialised devices, 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 (Artilex) (Ophtec BV, Groningen, The Netherlands) or (verilex) (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 (Artilex) or (Verilex) 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 inal BCVA worse than pre-operatively, due to recurrent uveitis. One patient (4%) need another surgery to ixate 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) Artilex or Verilex is beneicial in myopia, unsuitable for LASIK, matching or exceeding pre- operative BCVA in the overwhelming majority of the cases. With no major complications however long standing follow up is needed to avoid major complications.
