Effective lens position prediction and refractive accuracy

Ophthalmology · 2021

Explains why anterior chamber depth and lens geometry materially affect the final IOL estimate.

ELPBiometry

Axial length as the dominant refractive sensitivity factor

Eye · 2022

Shows that small axial length changes can shift the refractive target enough to change lens choice.
