主 题：High myopia Total keratometry Cataract surgery IOL power calculation
摘 要：Background:The accuracy of using total keratometry(TK)value in recent IOL power calculation formulas in highly myopic eyes remained ***:Highly myopic patients who underwent uneventful cataract surgery were prospectively enrolled in this prospective comparative *** one month postoperatively,standard deviation(SD)of the prediction errors(PEs),mean and median absolute error(MedAE)of 103 highly myopic eyes were back-calculated and compared among ten formulas,including XGboost,RBF 3.0,Kane,Barrett Universal II,Emmetropia Verifying Optical 2.0,Cooke K6,Haigis,SRK/T,and Wang-Koch modifications of Haigis and SRK/T formulas,using either TK or standard keratometry(K)***:In highly myopic eyes,despite good agreement between TK and K(P0.05),larger differences between the two were associated with smaller central corneal thickness(P0.05),which both presented smaller MedAEs than others(all P0.05),and statistically larger percentages than the other eight formulas(P0.05).Conclusions:Highly myopic eyes with thinner corneas tend to have larger differences between TK and *** XGboost enhancement calculator and RBF 3.0 formula using TK showed the most promising outcomes in highly myopic eyes.
