Impact of corneal astigmatism on refractive outcomes after phacoemulsification with implantation of a spherical IOL

open access: yesJournal 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 ...
