Vainer I, Mimouni M, Rabina G, et al. - Researchers examined changes in corneal refractive parameters in myopic and hyperopic patients undergoing refractive surgery with respect to age and gender. They performed a retrospective cross-sectional study including 62,422 eyes of 31,211 patients. Refractive surgery was performed for lower magnitudes of myopia and hyperopia with advancing age. Men relative to women exhibited a higher magnitude of cylinder in both myopic and hyperopic patients. In comparison, women vs men were significantly more myopic (spherical equivalent of −3.73 diopter [D] vs −4.07 D). The myopic group sphere had a positive correlation with age, whereas there was a negative correlation of other parameters with age: astigmatism, best-correct visual acuity (BCVA), flat K, steep K, average K, and J0. For hyperopic patients, a positive correlation of astigmatism, BCVA, flat K, average K, and central corneal thickness with age was observed, whereas there was a negative correlation of sphere, J0, and overall blurring strength with age. These findings may help to predict trends in patients attending refractive surgery.
