Final answer:
The uniformity and orderly packing of collagen fibers in the corneal stroma confer the property of transparency, crucial for clear vision, and allow for precise control over corneal shape, contributing to the majority of patients having normal distant vision.
Step-by-step explanation:
The uniformity of collagen fiber size and the ordered packing of the fibers in the corneal stroma gives it the unique property of transparency. This structural organization allows light to pass through the cornea with minimal scattering, providing the clarity necessary for good vision.
In addition, because the corneal shape can be finely controlled due to this uniformity, this contributes to over 90% of patients having normal distant vision post eye treatments that involve the cornea.
