Contact lenses have surgical functions as well. Soft lenses are useful in the treatment of non-refractive disorders of the eye. Contact lens protects a diseased cornea from constant rubbing and blinking of eyelids. They are comprehensively used in such treatment, which includes – bullous kerathopathy, dry eyes, corneal ulcers, corneal edema, corneal ectasis and other deadly diseases.
