Keratoconus is a disease of the eye where the front surface of the eye, called Cornea, becomes weak, leading to progressive thinning and stretching which gradually progresses. Gradually, the Cornea bulges forwards, leading to an irregular cone shape called keratoconus. This causes distortion and blurring of the image formed by the cornea. Usually this disease is bilateral, though the severity may vary between the two eyes. CXL is an innovative technology to halt the progression of the disease and at times stabilize the curvature of cornea in progressive diseases. The procedure can be done as a day care basis.
