Corneal edema

Corneal Edema is the swelling of the cornea following ocular surgery, trauma, infection and inflammation, as well as a secondary result of various ocular diseases. Corneal edema can also occur following over-use of certain types of contact lenses. The cornea is part of the eye's focusing system that transmits and focuses light into the eye. When the cornea swells, it may impair transmission of light, possibly decreasing vision.
