Researchers from the University of Melbourne have developed a way to grow corneal cells on a synthetic film that can then be implanted into the eye to help the cornea heal itself.
Using a hydrogel film, the scientists are reportedly able to grow a layer of corneal cells in the laboratory. The film with the cells is then implanted onto a patient's corneal surface. Once in place, the new cells reportedly restore the cornea's water-pumping activity so the cornea becomes transparent once more. The transplanted film completely biodegrades within two months and reportedly causes no adverse immune reactions.
The researchers reportedly believe this new treatment performs better than a donated cornea and they hope to eventually use a patient's own cells to create the transplantable film to help reduce the risk of rejection.
