IOL Power Calculation Features after Radial Keratotomy

IOL power calculation after keratorefractive surgery is an important applied aspect of cataract surgery. The probability refractive error especially high when calculating in patients with a history radial keratotomy. There no unified approach to the tactics and methodology for this category at moment. studies were conducted group 17 (26 eyes) RK. Haigis formula, which does not use keratometry predict ELP, was chosen as main one calculation. biometrics carried out on IOL-Master, but corrected TCP (Ray Traced) data obtained Galilei keratotomograph manually entered into optional fields. Thу Burrett True-K Hoffer Q used verification formulas, also using data. In all cases, postoperative refraction close emmetropic obtained. spherical component ranged from +0.5 -1.0 D, cylindrical — 0.0 4.0 according autorefractometry. Visual acuity without correction 0.4 1.0. Uncorrected visual 0.8 higher 65.38% cases. algorithm implemented by us formula combination individually adjusted keratometric Traced, Galilei), allowed significantly improve accuracy RK achieve target even cases complex irregular corneal topography.
