Postoperative residual refractive astigmatism of less than 0.50 D · people with astigmatism who are having cataract surgery (phacoemulsification)

Toric intraocular lens (IOL) probably leads to higher postoperative residual refractive astigmatism of less than 0.50 D compared with limbal relaxing incisions (LRIs) (moderate certainty).
