Guide to Pentacam Holladay EKR Report - quickguide.org
2022年1月12日 · The EKR 65 takes into account a weighted mean of 65 percent of corneal power within the 4.5 mm pupil diameter which could help avoid hyperopic surprise in special corneas like Keratoconus. The EKR 65 can be used for IOL power calculation with any standard IOL formula like SRKT, Hoffer Q, Holladay I, etc.
The accuracy of the trifocal IOL calculation using equivalent K ...
2023年8月31日 · The first map is the Holladay equivalent K-readings detail report (EKR 65%). This map is an upgrade of an actual net power map for practical use. For regular corneas (posterior radius equals 82% of anterior radius), cornea optical power values shift to the range of SimK values for the same eye.

Surgical Approach to Cataract Surgery with Keratoconus
Using the Holladay EKR-65 report on the Pentacam with 3 to 4mm simKs has also been used for calculating lens power in severely irregular corneas (see below). A standard K can also be used in patients with K's higher than 55 or in Ks that are unobtainable through biometry.
Pentacam Equivalent K-Reading - Journal of Refractive Surgery
2021年5月31日 · In short, with any tomographer or device that measures both the posterior and anterior radius and the thickness of the cornea, a value (EKR) can be calculated that is equivalent to the K-reading,...
Erd(?)s-Ko-Rado定理相关问题研究 - 百度学术
Erdos-Ko-Rado(简称EKR)定理涉及子集格的交的性质,是研究有限集的交族的最早结果,也是组合极值理论中最经典的结论之一.在过去的几十年间,许多学者研究了EKR定理及其各种推广,给出了EKR定理在其他偏序集上的模拟和极值结构的刻画.本文中我们讨论了EKR定理的一些 ...
