摘      要：AIM:To evaluate inter-device agreement of anterior keratometry obtained by the IOLMaster 500 and Pentacam HR in type 2 diabetic and non-diabetic ***:Corneal measurements were sequentially performed in 60 diabetes mellitus(DM)and 48 age and sex-matched controls undergoing cataract *** recorded included flat and steep keratometry,mean keratometry(Km),astigmatism magnitude,axis location,JO and J45 ***-Altman plots and intraclass correlation coefficients were used for examination of *** analyses were performed for astigmatism magnitude,diabetes duration,hemoglobin A1c(HbA1c)levels and diabetic retinopathy(DR)***:Agreement for Km and astigmatism magnitude were considered good and moderate,with 95%limits of agreement(LoA)of-1.09 to 1.23 diopters(D)and-0.83 to 0.86 D in DM group,respectively;and-0.59 to 0.72 D and-0.98 to 0.75 D in non-DM group,*** contrast,the 95%LoA for corneal axis exceeded the clinically relevant margins in both *** the total sample,only 41 eyes(38%)had a smaller than 5-degree *** duration,HbA1c levels and DR stage were not found to significantly affect *** regression showed that higher corneal power(P=0.021)and astigmatism magnitude(P=0.011)were associated with a decreased risk of having a difference in axis location greater than ***:In both groups,IOLMaster and Pentacam agree well for corneal power and moderately for ***,axis location disagreement is frequent in eyes with flatter corneas and small amounts of astigmatism.
