Statistical evaluation was performed utilizing a paired t-test and R2 analysis.Results: In females (396 eyes of 396 patients), mean keratometry ranged between 40.59– 47.78 D (44.27± 1.36 D), corneal astigmatism ranged between 0– 3.82 D (1.13± 0.74 D), and axial length ranged between 20.5– 31.32 mm (24.07± 1.74 mm). In males (333 eyes of 333 patients), mean keratometry ranged between 38.5– 46.95 D (43.54± 1.35 D; p< 0.001), corneal astigmatism ranged between 0.1– 3.97 D (1.15± 0.79; p=0.75), and axial length ranged between 20.41– 31.21 mm (24.57± 1.78 mm; p< 0.001). Both genders presented a shorter axial length in advanced age. Elderly males presented a higher percentage of against-the-rule astigmatism.Conclusion: Females may have steeper corneas and shorter eyes. A trend toward axial length reduction with age was observed in both genders. This finding is probably due to the difference in growth between generations, as the new ones have an higher size than the old ones.Keywords: axial eye length, corneal power, gender, mean keratometry, partial coherence interferometryDe Bernardo MZeppa LZeppa LCornetta PVitiello LRosa NDove Medical Pressarticleaxial eye lengthcorneal powergendermean keratometrypartial coherence interferometry.OphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 571-580 (2020)
