PURPOSE: To compare the findings of three corneal measuring devices for calculating surgically induced astigmatism (SIA) during cataract extraction.
METHODS: Patients' records were retrospectively reviewed to identify patients who had corneal astigmatism measurements before and at least 1 month after cataract surgery through 2.4-mm corneal incisions by all three tested devices (Lenstar LS900, Haag-Streit, Koeniz, Switzerland; IOLMaster 500, Carl Zeiss Meditec, Dublin, CA; and Atlas topographer, Carl Zeiss Meditec). Vector analysis was used to calculate the SIA for each measuring device.
RESULTS: Seventy eyes of 49 patients were included. All three measuring devices had similar SIA results: the median SIAs were 0.45 diopters (D) for the Lenstar, 0.41 D for the IOLMaster, and 0.47 D for the Atlas topographer (P = .884).
CONCLUSIONS: The three evaluated anterior corneal measuring devices produced similar results in measuring SIA. [J Refract Surg. 2015;31(4):244-247.].
