Swiss Advanced Vision, a company that designs, manufactures, and distributes a new generation of intraocular lenses for cataract surgery, recently announced a new product for post-cataract surgery, an intraocular lens (IOL) called InFo Instant Focus, that is says restores “perfect vision.”
The InFo lens is the first implant that offers unmatched quality of vision at all distances after removal of the crystalline lens in patients going through cataract surgery, the company says in a press release. As such, the lens is a solution for two challenging outcomes of such surgery, the correction of presbyopia (the improvement of near vision) and resolution capacity, or distinct image perception. Through its patented design, the InFo lens is said to be close to the natural process of accommodation and readily adjusts focus to near-, far- and midrange vision, without the brain being confused by the multiplication of focal points, and without halos or ghost images regardless light conditions.
“For patients, it’s life in real time again” Max Boysset, Swiss Advanced Vision’s CEO, said in the release. “The brain loves it: patients adapt to InFo almost instantly. Our mission is to restore their original vision after the surgery of cataract through a unique solution, without compromise on image quality or resolution.”
Myopia, which affects the muscles used to focus the lens of the eye, appears to have clinical implications for “accommodating,” or focusing, intraocular lens (IOLs) implants that help the eye adapt to different visual distances, according to a study in the journal Optometry and Vision Science, titled “The Effect of Age, Accommodation, and Refractive Error on the Adult Human Eye.”
Study results help to explain why there are individual differences in the focusing capacity of accommodating IOLs. A better understanding of differences in the diameter of ciliary muscles used to focus at varying distances may offer patients a more “tailored” IOL fit in surgeries to correct presbyopia, or the decline in near vision that happens with age, the researchers said in the study. The team found that eyes with myopia had a greater diameter of the ciliary muscle ring, and that the effect was considerably superior to the age effect on vision.
