The exact reason for the disease is not known. There are many theories like excessive eye rubbing and genetic predisposition to deficient collagen cross linking making the cornea weak. There is no scientific evidence to support this.

Procedures like C3R are done to strengthen the cornea and halt the progression of disease.
