Researcher Dr Nick Di Girolamo said: 'The procedure is totally simple and cheap.
'Unlike other techniques, it requires no foreign human or animal products, only the patient’s own serum, and is completely non-invasive.
'There's no suturing, there is no major operation. You don’t need any fancy equipment.'
The contact lenses used in the operation are already widely used after eye surgery.
The researchers hope the technique can be adapted for other parts of the eye, such as the retina, and even elsewhere in the body.
