Silicone ring addresses challenges of precise capsulorhexis creation
Disposable device provide simple, cost-effective option for sizing, positioning opening
A silicone ring-shaped device for assisting continuous curvilinear capsulorhexis creation provides a guide for precisely sizing and positioning the capsular opening.
Denver—A new device for guiding anterior capsulotomy (Verus Capsulorhexis Device, Mile High Ophthalmics) is an easy-to-use option that will allow surgeons—regardless of expertise and operating environment—to size and center a continuous curvilinear capsulorhexis (CCC) better, and at minimal cost compared with a femtosecond laser, said its inventor, Malik Y. Kahook, MD.
“Data from multiple studies demonstrate that capsulorhexis size and location can affect visual outcome after cataract surgery secondary to their effect on IOL position,” said Dr. Kahook, The Slater Family Endowed Chair in Ophthalmology, vice chairman, clinical and translational research, and professor of ophthalmology, University of Colorado Anschutz Medical Campus, Denver. “However, capsulorhexis creation remains the most difficult step of cataract surgery, and successful capsulorhexis is especially challenging for ophthalmologists in training.
“The new device we developed addresses the steep learning curve of capsulorhexis,” he added. “We believe it will allow even residents performing their first cases to make the capsulorhexis consistently, and it will provide all surgeons access to the benefits that come with a better capsulorhexis without the cost and technical requirements of a femtosecond laser.”
