Cornea, 2019
PURPOSE To compare the effect of 3.0 and 2.0 mm opposite clear corneal incisions (OCCIs) in phacoemulsification on reduction of preexisting corneal astigmatism, and their impact on corneal aberrations.

The components of adult astigmatism and their age‐related changes
Ophthalmic & physiological optics, 2019To study the corneal and internal astigmatism and the age‐related changes underlying the known refractive shift with‐the‐rule (WTR) towards against‐the‐rule (ATR) astigmatism.

It has been pointed out that the meridional object and image foci as well as the meridional center of curvature will lie on the same straight line if the condition Delta (n cos(2)i/t) = Delta (n/t) is satisfied. The surfaces fulfilling this condition do not introduce astigmatism; hence they have been called minimal astigmatism surfaces. The generalized
