Early symptoms include blurry vision upon wakening which improves during the morning, [2] as fluid retained in the cornea is unable to evaporate through the surface of the eye when the lids are closed overnight.

Therefore, keratoconus is a contraindication to refractive surgery. Corneal topography and pachymetry are used to screen for abnormal corneas. Furthermore, some people ...

    Treatment options include contact lenses and intrastromal corneal ring segments for correcting refractive errors caused by irregular corneal surface, [7] [8] corneal collagen cross-linking to strengthen a weak and ectatic cornea, [9] or corneal transplant for advanced cases.

    [11] [14] [9] Corneal transplantation is a management option when there is severe corneal melting or perforation although one possible disadvantage is the risk of rejection. [14] Surgical treatment helps maintain the integrity of the globe, but it is usually complementary because it alone cannot influence the underlying immunological process. [7]
