At the outset we would like to throw some light on curable blindness, one of the causes of which is corneal blindness.
The cornea, which is the transparent portion of the eye or a button in front of the colored iris and round pupil of the eye, is a surface, which converges the light rays to focus on the retina. Loss of transparency in the cornea results in blindness, which can be cured by corneal transplant. This surgery involves replacing the damaged cornea by a cornea from a donated eye. There are 15 million cases of this type of blindness out of which 4.6 million are less than 45 yrs and 60% less than 12 yrs. The demand for this corneal tissue is far greater than its supply.
