Surgical approaches to correct corneal astigmatism at time of cataract surgery: a mini-review [PDF]
International Journal of OphthalmologyAmong refractive errors, astigmatism is the most common optical aberration, where refraction changes in different meridians of the eye. It causes blurred vision at any distance and includes corneal, lenticular, and retinal astigmatism.

Correlation Between Stereoacuity and Experimentally Induced Graded Monocular and Binocular Astigmatism [PDF]
Journal of Clinical and Diagnostic Research, 2016 Introduction: Stereopsis, the highest grade of binocular single vision, is affected by various factors, such as mis-alignment of visual axes, refractive errors especially anisometropia and astigmatism, both of which may result in amblyopia. There are
