Ive always felt that the lenses should fit your eye, and you shouldn’t force eyes to ‘fit’ the lens. Maybe more an issue with selection of base curves, but it also applies to fitting patients with lenses that are too large.
We choose diameter to provide good coverage. So yes, a larger cornea will require a larger diameter lens.
In the grand scheme of things, though, a 14.5 is a rather large diameter lens; thus more prone to being too big on many patient’s eyes (larger diameter is typically used for toric lenses).
I’m not sure what you mean by how the number makes your eyes bigger?
The diameter of the lens just means how many millimeters is it from one side to the other. Some are 9.2, some are 15.
