Haigis Formula Dr. Wolfgang Haigis Head of the Biometry Department University of Wurzburg Eye Hospital Users Group for Laser Interference Biometry (ULIB) One of the final frontiers in ophthalmology is the consistently...
Jul 4, 2024 · The Haigis formula, like other optical formulas, is based on thin lens optics. However, while all other formulas use only one constant (like the ACD constant, the A-constant, or the surgeon factor) for a...
目前SRK/T 和Haigis 公式都被普遍应用于临床上长眼轴白内障眼计算IOL屈光度数,关于两者谁更胜一筹的问题许多学者进行讨论验证,在没有对公式进行优化的背景下,多数结论倾向于Haigis效果更佳,尤其是对于超长眼轴。
The Haigis formula was analyzed with respect to its usability for eyes after laser surgery for myopia and modified accordingly. Correction curves for IOLMaster keratometry were derived from previous studies. The new f...
Nov 18, 2008 · The new Haigis-L formula for calculating appropriate IOL power in patients who have previously undergone refractive laser surgery for myopia is described in this article by the formula's creator, Wolfga...
Jun 11, 2021 · To evaluate the accuracy of refractive prediction by the Haigis-L formula compared to four other IOL power calculation formulas in eyes with extremely long axial lengths (AL > 29.0 mm) after LASIK ...
计算基于 Haigis-L 公式的 IOL 屈光度的预期术后屈光度，并与从患者实际屈光度获得的球面等效值 (SE) 进行比较。 计算预测误差 (PE) 和平均绝对误差 (MAE)。
For the IOL power calculation part, the Haigis-L and the Haigis formula are actually the same. The only difference between the two is that the myopic version of Haigis-L first calculates a new corneal radius based on ...
Conclusions: The Haigis-L formula was relatively accurate in predicting extreme long axis (>29.0 mm) eyes after myopic LASIK surgery but less accurate for eyes with extremely flat corneas (<35 D). SRK/T corrected K an...
