The Haigis formula was analyzed with respect to its usability for eyes after laser surgery for myopia and modified accordingly. Correction curves for IOLMaster keratometry were derived from previous studies. The new formula was checked using the postoperative results of 187 cataract procedures in which 32 IOL types were implanted by 57 surgeons. Akcay et al. evaluated two foldable AC IOLs for high myopia in a prospective, interventional case series. The investigators implanted the Artiflex IOL Ophtec BV, an iris-claw lens, in 62 eyes and the ICare phakic IOL Cornéal, an angle-supported lens, in 42 eyes. The range of myopia treated was -7.75D to -26.00D spherical equivalent.
