And in people with astigmatism, the cornea has two different curvatures which focus light at two distances and produce blurry vision. Even those with perfect vision will eventually suffer from presbyopia, or “aging eyes.” As...

The lower prevalence of hyperopia in adults was predominantly explained by increasing astigmatism with age. Emmetropization (>2D change from before 3 years to adolescence) was seen in 22.2%. There was no influence on foveal hypoplasia grade on the degree of refractive errors throughout life; (...
MEPEDS[51] reported that although an overall decrease was found in the prevalence of astigmatism throughout the 6- to 72-month age range in African-American and Hispanic children, the most rapid change occurred between 6 to 24 months in this Hispanic population. ...
Age Differences in Axial Length, Corneal Curvature, and Corneal Astigmatism in Marfan Syndrome with Ectopia Lentis For the FLC, the MFs of the input and output variables can be in triangular, generalized bell, Gaussian, trapezoidal, and sigmoidal forms with a different number of fuzzy sets (FS...
The severity of irregular astigmatism at the same stages of KC had a significant effect on OCT measurements. It may therefore be beneficial to know the amount of change/deviation in OCT measurements in keratoconus patients and to report which parameters exceed the standards so that OCT can be ...
