Key takeaways:
- The lenses decrease higher-order aberrations via personalized inverse aberrations applied to the lens.
- Lens fit is customizable through proprietary Zenlens technologies.
Bausch + Lomb announced the U.S. launch of Zenlens Chroma HOA scleral contact lenses, designed to reduce symptoms such as halos and glare and correct advanced higher-order aberrations, according to a press release.
“Using Zenlens Chroma HOA custom technology, the unique higher-order aberrations of each patient are measured and corrected on the front surface of the stable-fitting scleral lens,” Jason Jedlicka, OD, chief of cornea and contact lens service and clinical professor at Indiana University School of Optometry and a consultant to Bausch + Lomb, told Healio.
“This approach can transform a patient’s vision — for instance, improving from 20/30 with a standard gas permeable lens to 20/20 vision with this custom HOA-corrected lens,” Jedlicka said. “It offers patients with irregular corneas the opportunity to achieve improved vision, rather than settling for what was previously considered ‘pretty good.’”
The lenses decrease higher-order aberrations through the use of personalized inverse aberrations applied to the front part of the lens. The fit of the lens can be customized using Zenlens’ SmartCurve technology, which allows for simplified scleral fitting, as well as Bi-Elevation technology, which eases scleral alignment and reduces lens decentration, chamber fogging, lens impingement and conjunctival impression rings, according to the Zenlens website.
“Zenlens Chroma HOA is a high-quality, customizable lens that fills a critical gap in scleral lens vision correction, especially for patients with complex corneal irregularities,” Yang Yang, president, global vision care, Bausch + Lomb, said in the release. “Eye care professionals in the U.S. now have a new solution for patients that previously had limited options to improve vision quality.”
