Study: Gender is not relevant in higher-order aberrations

DENVER – Gender does not appear to play a role in the differences in various commonly studied higher-order aberrations (HOA), according to a poster presented here at the American Academy of Optometry meeting.
Melanie Crandall, OD, and fellow researchers took into account previous work that has shown that, for both children and adults, women have steeper corneas, stronger crystalline lenses and shorter eyes compared to males. Because each of these factors could affect wavefront aberrations, the researchers sought to determine if this was the case.
In the study, HOAs were measured for 283 female and 139 male eyes, with the two groups matched for age. An aberrometer was used to measure root mean square (RMS) values of spherical aberration (SA), coma and total HOA. These values were subsequently compared between the two groups. Using repeated measures ANOVA, the examiners assessed the hypothesis that there is a difference in wavefront aberrations between males and females.
The results found that gender does not represent a significant factor for total HOAs RMS (P = 0.298), SA RMS (P = 0.745) or for coma RMS (P = 0.629).
