New article: Estimating principal plane positions for ocular power calculations in children and adults

As lens biometry is still difficult to obtain, authors may be inclined to make assumptions about the principal plane positions in the eye. The assumed values are usually based on the proportions of adult eye models, but these may be quite unsuitable for use in children's eyes. To this end, the works of Mutti et al. and Atchison et al. were used to derive more appropriate, age dependent estimates of the principal plane positions, enabling more accurate power calculations.
