Final answer:
The word root "kerat" in "keratotomy" refers to the cornea, and the procedure involves making an incision in the cornea to correct visual issues.
Step-by-step explanation:
The word root "kerat" in the term "keratotomy" refers to the cornea, which is the clear, dome-shaped surface covering the front of the eye. A "keratotomy" is a surgical procedure that involves making an incision in the cornea, often to correct visual impairments like myopia (nearsightedness) or astigmatism.
Therefore, the term "keratotomy" can be broken down into two parts: "kerat-" meaning cornea, and "-otomy" meaning to cut or make an incision.
