Abstract

This study demonstrates the feasibility of using OCT to quantify microfluctuations in ocular biometry at steady-state accommodation. The preliminary results confirm the presence of two main frequency components in mechanical fluctuations of the lens consistent with prior studies on microfluctuations of optical accommodation (LFC: ≤ 0.6Hz and HFC: 1.0Hz – 2.5Hz). Both frequency components increased with accommodation. This study also measured axial eye length (AEL) fluctuations and found a peak around 2.5-3 Hz. The fluctuations in AEL may be caused by eye movements such as saccades.
