Keratoconous is derived from Greek word "Kerato" means cornea and "conus" means cone. It is a non-inflammatory eye disorder linked to the progressive thinning of corneal stroma, asymmetrical corneal distortion and protrusion. Visual acuity, headache, photophobia, monocular diplopia and glare are some of the symptoms associated to keratoconous. Light microscopy, confocal microscopy and optical coherence tomography are the techniques utilized to observe corneal changes in keratoconous. Intra stromal corneal ring segment, Corneal collagen cross linkages to stabilize the cornea, Corneal transplant are some of the treatment employed to treat KC.
