Intraoperative aberrometry reduces residual refractive astigmatism

Cataract surgery and toric IOL implantation yielded significantly less residual refractive astigmatism with intraoperative aberrometry than with standard methods, according to a study.In addition, preoperative keratometric cylinder was reduced, as measured by residual postoperative refractive cylinder, 57% and 75% of the time with the non-aberrometry and aberrometry groups, respectively.
