The SRK/T formula is a theoretical (T) approach to IOL power calculation under the SRK umbrella of empirical formulas using existing A-constants and optimization methods. Empirical optimization methods of the SRK/T model primarily consist of (1) postoperative ACD prediction, (2), a retina thickness correction factor and (3) corneal refractive ...

SRK/T、Haigis、Holladay 1、Hoffer Q等传统理论公式是基于人眼几何光学模型推导的理论公式并结合临床资料回归得出 [8] ，对于极值的生物学参数，如超长/短眼轴、平坦/陡峭角膜曲率等，传统公式预测的准确性下降 [9] 。

To develop this IOL power calculation formula, four IOL power calculation formulas (SRK/T formula, Holladay 1 formula using Cooke-Modified Axial Length [CMAL] in eyes with AL of <24.0mm and Wang Koch Non Linear Regression [WKNLR] in eyes with AL of ≥24.0 mm [1] [2] [3], HofferQ formula using CMAL in all eyes [1], Haigis formula in eyes with AL o...

原始公式为P=A-2.5L-0.9K srk/t公式包括前房深度、视网膜厚度修正系数和角膜屈光系数等。 最佳的手术后前房深度 前房深度（ 预测）＝角膜厚度＋补偿值 补偿值＝恒定的前房深度值－3.336 恒定的前房深度值＝0.62467×A－68.747

1990年5月1日 · A new implant power calculation formula (SRK/T) was developed using the nonlinear terms of the theoretical formulas as its foundation but empirical regression methodology for optimization.

2017年4月21日 · SRK/T公式、HOFFER Q公式、Holladay公式、Haigis公式置于测量和计算工人晶体屈光力的设备中，得到了广泛应用 [8, 10-12] 。新一代理论公式涉及多个重要参数。

本文基于SRK-T晶状体屈光度计算公式，利用Zemax实现光线追迹的方法，分析了采用不同A常数预算的人工晶状体分别植入到Hwey-Lan Liou眼模型和Gullstrand-Le Grand眼模型中对成像质量的影响情况，同时又对在植入不同光学结构的同屈光度人工晶状体情况下的人眼像质进行 ...

SRK/T公式 基于Fyodorov公式 c的预测公式为： c= H + offset offset= ACD常数-3.336 ACD常数＝ 0.62467A - 68.747 H为角膜到虹膜平面的距离 Haigis、 Hoffer Q 、Holladay2 和 SRK/T
