Description of intervention(s) / exposure
Myopics younger than 40 years old with more than 12 dioptres of myopia or who were not fit for Lassie assisted in situ keratomieusis (LASIK) were included . Group A was the Clear lens extraction with foldable intraocular lens implantation this is a one off intervention lasting approximately one half hour, and Group B was the Visian intra ocular contact lens (ICL) implantation this is a one off intervention lasting approximately one half hour . Patients were evaluated for visual and anatomic outcome, and complications
