Drug Delivering Contact Lenses Revealed

Scientists at Singapore’s Institute of Bioengineering and Nanotechnology have developed contact lenses that deliver eye medication to treat diseases like glaucoma. If the drug is water-soluble, it will be trapped within a network of tiny inter-connected, water-filled channels in the material. If it’s water-insoluble, it will be trapped within nano-spaces in the polymer matrix, and slowly leach out into the channels. In contact with fluid on the eyeball, these channels open up and release the drug
