摘要

<正>INTRODUCTION The front portion of the eye consists of a transparent layer called the cornea.The cornea is an important optical component for vision and plays a role in the specific refraction of the eye.The cornea normally has convexity but the amount of protrusion progressively increases in patients with keratoconus.In other words,the cornea prolapses forward.Keratoconus is a bilateral,typically asymmetric and non-inflammatory degeneration of the cornea caused by corneal protrusion as a result of progressive thinning of the corneal stroma.Corneal thinning generally occurs in the inferior,inferotemporal or central regions of the cornea~([1]).However,corneal thinning in the upper quadrants of the
