CHICAGO – Future advances in refractive cataract surgery hinge on an improved understanding of the role that higher-order aberrations and dysphotopsia play in patient dissatisfaction after cataract surgery, a speaker said here.
Many patients see 20/20 but have major issues with glare and light sensitivity, Randall J. Olson, MD, said in the Binkhorst Lecture opening the American Society of Cataract and Refractive Surgery annual meeting.
On the road to optical precision, dysphotopsia is very important, he said, with dysphotopsia correlating significantly with low patient satisfaction scores.
“It’s time to get around this issue and problem. Refractive precision is going to be demanded but thank heavens there’s a lot of technology out there that’s going to take us to a new level of precision,” he said, adding that soon being unhappy with 20/20 vision can become a thing of the past as long as these issues are addressed.
Effective lens position (ELP) has the greatest impact on refractive error, he said, and femtosecond laser-assisted cataract surgery has the potential to enable precise capsulorrhexis design that optimizes the ELP. Furthermore, intraoperative aberrometry shows the most potential to improve postoperative refractive outcomes.
In Europe, the Light-Adjustable Lens (Calhoun Vision) has shown promising results in recent studies, with 80% of patients seeing 20/20 with very small refractive errors, Dr. Olson said.
