"I know low levels of astigmatism will decrease the qual- ity of distance vision with a diffractive optic. If I think it's universally important to treat in the setting of diffractive optics, then I also think it's important to address all levels of astigmatism to improve quality of vision at distance with all lenses. Therefore, I treat all low levels of astig- matism when I'm trying to reach a refractive target that allows for independence from glass- es. I think that does provide better outcomes than we would get if we were not so focused on reducing residual astigmatism." At this point in the evolution of delivering excellent outcomes with cataract surgery, it's not reasonable to ignore astigmatism, Dr. Mc- Cabe said. "It's a fundamental part of how we can improve the visual function and quality of vision for our patients." He also said that industry will play a big role in helping to develop better ways of correcting astigmatism, especially low levels. "Moderate to high levels of corneal astigmatism can be effectively addressed with toric IOLs, but if we want to raise the bar and improve outcomes, we need to refine methods to treat lower levels, both on the clinical side and on the industry side." For example, Dr. Schallhorn said this could mean further developing and obtain- ing regulatory approval for toric IOLs for low levels of astigmatism. Whether it's addressing the astigmatism on the cornea/limbus (incision- al techniques, laser vision correction, or other methods) or with a toric IOL, Dr. Schallhorn said it's important to improve the accuracy and predictability of correcting astigmatism. Dr. McCabe agreed with the results of this study and said in her own experience, small amounts of residual astigmatism can impact quality of vision, especially when using more sophisticated optics that split light.
