Inflammation of the cornea
Geometric center

The point where lines that bisect the horizontal and vertical measurements of the lens in the boxing system intersect

The correct answer is: Inflammation of the cornea

Keratitis refers to inflammation of the cornea, the clear, dome-shaped surface that covers the front of the eye. This condition can be caused by infection, injury, or underlying medical conditions and can lead to redness, pain, and blurred vision. Option B refers to the geometric center which is not related to the term keratitis. Option C refers to the power of the eye's refractive system, not an inflammatory condition. Option D is a description of the boxing system and its measurements, not related to keratitis.
