Evidence of the Amplitude of Accommodation of School-Going Children in the 21^st Century. [PDF]

Br Ir Orthopt J, 2023
Purpose: The study sought to compare the normative amplitude of accommodation (AoA) in school-going children from studies in the 21st century, based on pooled estimates from meta-analyses, to assess their agreement to Hofstetter’s average formula ...

Diurnal variations of amplitude of accommodation in different age groups. [PDF]

PLoS One, 2019
Clinical assessment of amplitude of accommodation (AA) involves measuring the ability of the eye to change its optical power and focus on near tasks/objects. AA gradually decreases with increasing age.

Repeatability of the amplitude of accommodation measured by a new generation autorefractor. [PDF]

PLoS One, 2020
SIGNIFICANCE:This is the first study to validate the repeatability of objective measurements of amplitude of accommodation (AA) using the TONOREF III (NIDEK Co., Ltd., Japan), which can measure the AA in 30 seconds.

Correlation between ocular parameters and amplitude of accommodation

Indian J Ophthalmol, 2010
Aim: To study the relationship between ocular parameters and amplitude of accommodation (AA) in the peri-presbyopic age group (35-50 years). Materials and Methods: Three hundred and sixteen right eyes of consecutive patients in the age group 35-50 years,

A comparison in university students of the amplitude of accommodation determined subjectively

African Vision and Eye Health, 2016
Background: Historically, the push-up and the minus lens methods have been used for the measurements of the amplitude of accommodation, and the differences between the results of these methods are well known.

Objective Amplitude of Accommodation Computed from Optical Quality Metrics Applied to Wavefront Outcomes

Journal of Optometry, 2009
Purpose: We studied the accuracy and precision of 32 objective wavefront methods for finding the amplitude of accommodation obtained in 180 eyes. Methods: Ocular accommodation was stimulated with 0.5 D steps in target vergence spanning the full range of ...
