Thomas Meirick, MD, and Parisa Taravati, MD, University of Washington, summarized “Effect of residual astigmatism on uncorrected visual acuity and patient satisfaction in pseudophakic patients” from the August edition of the ASCRS Journal Club, which was recorded live at the 2021 ASCRS Annual Meeting.
Astigmatic keratotomy (AK) and limbal relaxing incisions (LRIs) are tools that can be used by surgeons to help correct low levels of astigmatism. Two surgeons discussed how these can reduce astigmatism and how they’re using them in practice.
A recent patient of Dr. Ristvedt’s presented for cataract evaluation wanting a trifocal IOL. Blurred Placido images indicated dryness, which was then treated before she returned for repeat measurements. The power and orientation of the patient’s astigmatism changed after treating the dry eye. Source: Deborah Ristvedt, DO
Managing astigmatism at the time of cataract surgery is a weighty topic with many variables. What technology to measure astigmatism—power and axis? How many measurements to take for reliability? How to ensure accuracy and consistency of measurements? What course of correction to take?

Total corneal astigmatism correction during cataract surgery could be either by eliminating it or leaving slight with-the-rule astigmatism.
