An injectable nanocomposite gel for replacing the eye lens could eliminate the need for complicated cataract surgery, say Japanese and Danish researchers.
Cataracts are caused by optical defects of the natural lens that develop with age and can lead to increasingly blurred vision and blindness. Currently, plastic lenses can be used to surgically replace the natural lens but they are not a perfect replacement, for example they tend to be monofocal, limiting the eye’s ability to focus outside a set range. They are also not a proper fit, which can cause problems such as misalignment.
