Abstract
High myopia, one of the most prevalent eye diseases worldwide. With the improvement in surgical techniques and biometry devices, cataract surgery is now considered a form of refractive surgery. Accurate preoperative intraocular lens (IOL) power calculation is crucial in achieving satisfactory results.The prediction of refractive outcomes after cataract surgery has steadily improved, with more recent intraocular lens (IOL) power formulas generally outperforming those of prior generations. Yet there is still considerable debate about which formula provides the most accurate refractive prediction. We aimed to compare the Lenstar optical biometry versus conventional ultrasonic biometry in high myopic eyes undergoing cataract surgery concerning the accuracy of IOL power calculation before cataract surgery.This study included 20 high myopic eyes of 20 patients, of which 15 (75%) females and 5 (25%) males. Thirteen (65%) eyes were left sided and 7 (35%) eyes were right sided. The mean age of the patients was 46.8 ±11.3 years (range, 28 to 72 years).
