Accommodating lenses for cataracts
Traditional cataract surgery has primarily been used to restore distance vision.With this traditional approach, post-cataract surgery near vision is corrected using eyeglasses.The technology functions very much the same as progressive eyeglasses and multifocal contact lenses.The difference is that the lens is surgically implanted in the eye and offers a permanent, maintenance-free solution to presbyopia.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 In Fo Instant Focus, that is says restores “perfect vision.” The In Fo 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.There are several different types of multifocal IOLs approved by the FDA for use in the U. The lenses below are the most commonly used multifocal IOLs in the U.
You might find it surprising that after undergoing vision correction surgery, you still require eyeglasses for near vision reading.
Well, what if there was a way to have cataract surgery and restore vision at all distances? As the name implies, a multifocal IOL offers more than one lens power.
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.
Through its patented design, the In Fo 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.
