Anterior chamber pachymetry during accommodation in emmetropic and myopic eyes

Optical pachymetry was performed on 15 nearly emmetropic and 15 myopic subjects with accommodation fully relaxed and with 3.00 and 6.00 dioptres of stimulus to accommodation. No significant difference was found between the change in anterior chamber depth per dioptre of stimulus between the two groups. This is in agreement with theoretical considerations, which suggest that a change in the length of the vitreous does not much affect the optical efficiency of the crystalline lens.
