Asymmetric multifocal IOL improves visual acuity at low level of residual astigmatism

A rotationally asymmetric multifocal IOL was associated with positive visual outcomes at low levels of residual refractive astigmatism, according to a study conducted in the United Kingdom.“The angle of residual corneal astigmatism in relation to IOL placement did not have a significant effect on postoperative outcomes,” the study authors said.
