You should find that they all agree on the range of iris variation (a few measured up to 13mm but most say around 12.5) and the average iris diameter (around 11.8mm). The vertical corneal diameter (vertical visible iris diameter, VVID) was the distance between the superior and inferior imaginary tangents to the corneal circumference. In measuring the VVID it was occasionally necessary to lift the eyelids with minimum pressure being applied to the globe.
