Primary Outcome Measures

Name	Time	Method
1.The aim of this study is to evaluate and compare the visual and refractive outcome after implantation of Eyecryl, a hydrophilic acrylic phakic intraocular lens implant from Biotech Vision Care (EP IOL) in moderate and high myopia and astigmatism with an established method using Visian Implantable Collamer Lenses (EVO/EVO+ latest model of ICL, STAAR Surgical Company). <br/ ><br> <br/ ><br>Timepoint: day 1, 1month, 3month and 6 month and 12 month
