Intracapsular accommodation mechanism in terms of lens curvature gradient
Ophthalmic and Physiological Optics, Volume 44, Issue 2, Page 334-346, March 2024.Abstract The intracapsular accommodation mechanism (IAM) may be understood as an increase in the lens equivalent refractive index as the eye accommodates. Our goal was to evaluate the existence of an IAM by analysing observed changes in the inner curvature gradient of the lens.

Variation of the Magnetic Disaccommodation Dynamics In Zero-magnetostrictive Amorphous Ribbons
, 1992 The relaxation of magnetic disaccommodation is investigated in a zero-magnetostrictive amorphous alloy. Domain-structure changes induced by field annealing strongly modify both the disaccommodation intensity and its kinetics, indicating that the short ...

Dynamic accommodation in rhesus monkeys [PDF]
, 2002 The dynamics of Edinger–Westphal (EW) stimulated accommodation were studied in two young rhesus monkeys to understand the relationships between accommodative amplitude and rates of accommodation and disaccommodation. Accommodative responses were recorded

Magnetic Relaxation of Permeability (Disaccommodation) in an Amorphous Ferromagnetic Fe-Si-B-C Alloy [PDF]
Disaccommodation (DA) was examined in the temperature range from -196℃ to the Curie temperature for an amorphous Fe_ Si_ B_ C_ alloy, which exhibits a maximum around 250℃. When the alloy is annealed successively at various temperatures below 220℃, the DA

Age related changes in accommodative dynamics in humans [PDF]
, 2006 Age related changes in the dynamics of accommodation (far to near focus) and disaccommodation (near to far focus) are reported in this study. Dynamic responses to step stimulus demands from 1D to 6D, in 1D steps, were recorded with a PowerRefractor in 66
