E W CATARACT 6 9 The unique advantages and limitations of multifocal IOLs require surgeons to focus on patient selection and screening to ensure their optimum use A mid continuing concerns t hat multifocal lenses are fraught with unwanted side effects, surgeons stress the importance of using careful patient screening and selection criteria to maximize the likelihood of patient satisfaction. Multifocal IOLs—a popular lens choice for motivated patients who would like to achieve spectacle independence—continue to face challenges in their postop outcomes, noted a literature review in the January issue of Current Opinion in Ophthalmology. The review con- cluded that existing research has not provided significant improvements in resolving the current problems of blurred vision and dysphotopsias. Given those challenges, sur- geons' efforts to increase the likeli- hood of positive clinical outcomes and minimize postop complications a re increasingly critical. Preop screening detailed Among the evolving multifocal lens patient selection procedures used by Jay S. Pepose, MD, director, Pepose Vision Institute, and professor of clinical ophthalmology, Washington University School of Medicine, St. L ouis, Mo., is a Humphrey topogra- pher (Carl Zeiss Meditec, Jena, Germany) to analyze the corneal wavefront. If either the horizontal or vertical coma term at a 6 mm optical zone is over 0.3 microns, he avoids implanting a multifocal IOL. by Rich Daly EyeWorld Contributing Writer Preparation, patient fit keys to multifocal success L c L c L s s The apodized refractive-diffractive SN6AD1 (Alcon) features circular diffractive discontinuities on the anterior central optic.
