New contact lenses with stem cells capable of restoring vision can now forever changed ophthalmology, reports The Daily Mail, citing information specialists at the University of Sheffield.
In essence, the lens is a biodegradable implant containing cells which multiply and thereby allow the eye cured themselves. The technology was originally created to treat corneal injury resulting from physical impact scar imposed after surgery, a number of hereditary diseases and infections, and dry eye syndrome.
Corneal injury is a person pain, severe light sensitivity, sensation of mote in the eye and blurred vision. The implant is exactly mimics the characteristics of the eye, representing a thin shell, which serves as a scaffold for stem cells. Thus, now the cells themselves or transplantation using donor cornea is not necessary.
It should be noted that implant cells are fully intact, since the shell consist of small so-called "pockets" which protects the cells and combining them together. The central portion of the sheath is thinner that allows cells to integrate gradually as the expansion of the material in the eye.
Lenses used to create a biodegradable material is completely safe and has been used previously in the manufacture of absorbable sutures for stitching wounds. A number of laboratory tests proved the effectiveness of the new method. Soon in India are planning to start clinical trials.
