New implantable contact lenses may offer vision correction for people with moderate to severe myopia, study suggests

WebMD (7/13, Warner) reported that, according to a study published in the July issue of the Archives of Ophthalmology, “a new type of implantable contact lens (ICLs) may offer an alternative to glasses or regular contacts for people with moderate to severe nearsightedness (myopia).” The study demonstrated that the Visian ICLs “made of a collagen-like polymer substance…were safe and effective at correcting myopia in the majority of recipients.” For the study, researchers from Japan’s University of Kitasato School of Medicine “assessed the safety and effectiveness of the implantable lenses in 56 eyes of 34 people with moderate to severe myopia who had the procedure in Japan.” They found that “four years after the surgery, 79 percent of the eyes were within 0.5 diopter…of the targeted correction and 93 percent were within one diopter.” In addition, “the collagen polymer lens also performed well in terms of safety, predictability, and stability in people with high myopia throughout the four-year follow-up,” the investigators said.
