Amplitude, Latency, and Peak Velocity in Accommodation and Disaccommodation Dynamics. [PDF]
Biomed Res Int, 2017 The aim of this work was to ascertain whether there are differences in amplitude, latency, and peak velocity of accommodation and disaccommodation responses when different analysis strategies are used to compute them, such as fitting different functions to the responses or for smoothing them prior to computing the parameters.

The effects of color and neutral density filters on dynamic accommodation in individuals with mild traumatic brain injury [PDF]
Frontiers in NeuroscienceIntroductionVisual symptoms related to accommodation are frequently reported after mild traumatic brain injury (mTBI), yet the effect of spectral and luminance-altering filters on dynamic accommodative performance remains unclear.

Real-Time Measurement of Ocular Wavefront Aberrations in Symptomatic Subjects. [PDF]
Biomed Res Int, 2018 The purpose of this work was to study the real‐time changes of the optical properties of the eye with accommodation in subjects with symptoms of accommodative disorders. From ocular aberrations, it is possible to compute several parameters like the response and lag of accommodation.

Initial destination of the disaccommodation step response
Vision Research, 2006 Peak velocity and peak acceleration of disaccommodation step responses remain invariant of response magnitude for a constant starting position and they increase linearly with proximity of starting position. This suggests that disaccommodation response is initiated towards an initial (default) destination and is switched mid-flight to attain the desired
