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.
