目的:探讨隐形眼镜基线(BC)和角膜曲率结果(Krf)之间简单的数学相关性.方法:本回顾性研究包括350例400只圆锥角膜的眼睛,其先前五年在学院眼科中心验配硬性隐形眼镜.根据角膜曲率结果患者被分为五组,分别为Krf<7,Krf:7-8,Krf>8,Krf-Krs(两个角膜曲率的差异;平坦和陡峭)=0.3- 0.6,Krf - Krs> 0.6mm 1至5组,使用多元线性回归和蒙罗相关系数推测公式.结果:除了第3组患者,可以在所有组中发现线性相关.第1组,BC= 0.211×5.904 Krf.第2组,BC=0.456× Krf4.160.第4组,BC=0.321×5.219 Krf.第5组,BC=0.337×Krf+5.090.结论:RGP验配新公式的发展,可增强眼科医生工作的信心,避免不必要的和频繁的眼镜试验.通常的隐形眼镜验配方法需要更换新的公式,从而帮助节省时间和费用.

AIM: To find a simple mathematical correlation between the lens base curve (BC) and keratometry findings (Krf).METHODS: This retrospective study included 350 patients(400 keratoconic eyes) previously fit with rigid contact lenses at an academic eye center over a five years period. The patients were classified into five groups based on the keratometry findings [Krf <7; Krf:7-8; Krf >8; Krf-Krs (difference between two keratometry; flat and steep) =0.3- 0.6; Krf-Krs >0.6mm] as groups 1 to 5, respectively. Multivariate linear regression and Munro's correlation coefficient were employed to defer the formulas.RESULTS: A linear correlation could be found in all groups except for patients in group 3. For group 1, BC=0.211×Krf+5.904. For group 2, BC=0.456×Krf+4.160. For group 4, BC=0.321×Krf+5.219. For group 5, BC=0.337×Krf+ 5.090.CONCLUSION: The development of new formulas for RGP fitting enables ophthalmologists to work with confidence and prevents unnecessary and frequent lens trials. The customary lens fitting methods are needed to be replaced by new formulas, which help to save time and costs.
