Comparison of Newer IOL Power Calculation Methods for Eyes With Previous Radial Keratotomy
PURPOSE To evaluate the accuracy of the optical coherence tomography-based (OCT formula) and Barrett True K (True K) intraocular lens (IOL) calculation formulas in eyes with previous radial keratotomy (RK). METHODS In 95 eyes of 65 patients, using the actual refraction following cataract surgery as target refraction, the predicted IOL power for each method was calculated. The IOL prediction e...
متن کاملComparison of IOL power calculation methods and intraoperative wavefront aberrometer in eyes after refractive surgery.
PURPOSE To compare preoperative methods for calculating intraocular lens (IOL) power versus the intraoperative wavefront aberrometer in eyes with a history of refractive surgery. METHODS A retrospective study of 46 eyes (33 patients) with previous refractive surgery that underwent subsequent cataract surgery was conducted. Suggested IOL power predicted by ORange intraoperative wavefront aberr...
متن کاملiol power calculation in patients with previous rk
purpose: to report the results of different methods for true corneal power and intraocular lens (iol) power calculation in 10 eyes with previous radial keratotomy (rk) with or without astigmatic keratotomy. methods: in this case series including 10 eyes of 7 patients who had undergone rk with or without astigmatic keratotomy, we firstly determined corneal power using two methods: contact lens m...
متن کاملComparison of Two Toric IOL Calculation Methods
Purpose To compare two calculators for toric intraocular lens (IOL) calculation and to evaluate the prediction of refractive outcome. Methods Sixty-four eyes of forty-five patients underwent cataract surgery followed by implantation of a toric intraocular lens (Zeiss Torbi 709 M) calculated by a standard industry calculator using front keratometry values. Prediction error, median absolute err...
متن کاملOutcomes of Phacoemulsification Using Different Size of Clear Corneal Incision in Eyes with Previous Radial Keratotomy
OBJECTIVE To evaluate visual outcomes and complications after phacoemulsification in eyes with cataract and previous radial keratotomy (RK) cuts using different sizes of clear corneal incisions. METHODS The study was a retrospective study. Thirty eyes with cataract and previous RK underwent phacoemulsification and intraocular lens (IOL) implantation. Among them 7 eyes had 8 RK cuts, 13 eyes h...
