Final answer:
A topographic map is the most important type of display for Orthokeratology (ortho-K) because it provides detailed information about the shape of the Earth's surface.
Step-by-step explanation:
A topographic map is the most important type of display for Orthokeratology (ortho-K) because it provides detailed information about the shape of the Earth's surface.
Ortho-K is a non-surgical procedure to correct vision by reshaping the cornea using specially designed contact lenses. The effectiveness of ortho-K depends on the precise measurement of the corneal topography, which is the detailed map of the cornea's shape and curvature.
By analyzing the topographic map of the cornea's surface, optometrists can design customized ortho-K lenses that will gently reshape the cornea overnight, allowing the wearer to see clearly during the day without the need for glasses or contact lenses.
