Background: Accurate measurement of the axial length (AL) of the eye is a critical factor in determining the appropriate intraocular lens (IOL) power for cataract patients. Small measurement errors can result in significant postoperative refractive surprises, making the choice of biometry device essential. Objective: This study aims to compare the accuracy and applicability of two biometry devices—A-scan ultrasound and the IOL Master—in measuring axial length across various age groups of cataract patients. Methods: A total of 80 patients from Imam Al-Hajjah Hospital were retrospectively studied over the years 2019 to 2022. Axial length measurements were obtained using both A-scan and IOL Master devices. Data were analyzed to evaluate device precision, correlation with patient age, and the suitability of each method under different ocular conditions. Results: The findings demonstrated that the IOL Master provides more accurate and consistent AL measurements due to its non-contact optical interferometry technique. However, in cases of dense cataract or media opacities, where light-based methods fail, A-scan ultrasound remains a necessary alternative despite its higher risk of measurement error due to corneal compression. Conclusion: Choosing the appropriate biometry device significantly impacts the accuracy of IOL power calculations. While the IOL Master is preferable for its precision, A-scan ultrasound serves as a valuable backup in advanced cataract cases. Awareness of each method’s limitations is essential for optimal surgical outcomes.
