An MRI would never be used to measure focusing properties of the eye in a clinical setting. It would be a very expensive, time consuming and “invasive” (probably not the right word) way to measure the length of the eye but I doubt it could measure the focusing power of the cornea or lens.

Autorefraction or retinoscopy would measure the focusing power of the whole eye. You can derive the power of the lens from biometry (measures the length of the eye and focusing power of the cornea).

Not clinically, no. But for research purposes a group could absolutely write a grant proposal to study development of the eye in early childhood.
