Clinical application of accommodating intraocular lens [PDF]
The present review describes recent advances in application of accommodating intraocular lenses (AIOLs). Standard monofocal intraocular lenses (MIOLs) only correct distance vision, while AIOLs are designed to allow both good distance vision and near ...

Visual discomfort and blur [PDF]
Certain visual stimuli, such as striped patterns and filtered noise, have been reported to be uncomfortable. Some filtered noise patterns judged as uncomfortable are those with a relative decrease in contrast amplitude at high spatial frequencies ...

Changes in Lens Thickness and Amplitude of Accommodation with Age [PDF]
Introduction: The human crystalline lens is a transparent, biconvex structure in the eye that, along with the cornea, helps to refract light to be focused on the retina and, by changing shape, it adjusts focal distance and this function of the lens is

Analysis of the calculation of the amplitude of accommodation [PDF]
The push-up method is routinely used to measure the amplitude of accommodation. In this method the diopter value corresponding to the nearest point that the eye can focus is determined, wearing his neutralizing lens, but not the value of the maximum ...

Investigation of amplitude of accommodation among Ghanaian school children [PDF]
Deficient amplitude of accommodation is the most frequently used criteria in an optometric practice in diagnosing whether a patient has accommodative insufficiency. This deficiency is determined based on an age-related expected finding calculated using Hofstetter's equation derived from Donder's and Duane's data.

Introduction: Learning problems influencing the social and psychological development of children may result from poor visual acuity (VA), insufficient amplitude of accommodation and receded near point of convergence (NPC). This study assessed Grade 4 and

Optical factors influencing the amplitude of accommodation
The purpose of this work was to find plausible predictors among optical parameters that may explain the inter-individual differences in subjective amplitude of accommodation not explained by age. An exploratory multivariable regression analysis was carried out retrospectively on a dataset with 180 eyes from 97 subjects (ages ranged from 20 to 58years).
