Distribution of posterior corneal astigmatism according to axis orientation of anterior corneal astigmatism. [PDF]
PLoS ONE, 2015 To investigate the distribution of posterior corneal astigmatism in eyes with with-the-rule (WTR) and against-the-rule (ATR) anterior corneal astigmatism.We retrospectively examined six hundred eight eyes of 608 healthy subjects (275 men and 333 women ...

Astigmatism and vision: should all astigmatism always be corrected? [PDF]
British Journal of Ophthalmology, 2013 As technology and medical devices improve, there is much interest in when and how astigmatism should be corrected with refractive surgery. Astigmatism can be corrected by most forms of refractive surgery, such as using excimer lasers algorithms to ablate the cornea to compensate for the magnitude of refractive error in different meridians.

Effects of Lens-Induced Astigmatism at Near and Far Distances [PDF]
, 2023 Purpose: To investigate and compare the degradation of visual acuity (VA) in myopic presbyopes due to lens-induced astigmatism at near and at far distance. Patients and Methods: Fourteen corrected myopic presbyopes were recruited.

Journal of Ophthalmology, 2021 Background: To date, particular emphasis is being put to correction of preoperative corneal astigmatism in phacoemulsification, since approximately 30% of the world’s population has astigmatism of at least 0.75D which results in decreased visual acuity ...
