Clinical application of accommodating intraocular lens [PDF]
International Journal of Ophthalmology, 2018 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 ...

Changes in Lens Thickness and Amplitude of Accommodation with Age [PDF]
International Journal of Anatomy Radiology and Surgery, 2020 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]
, 2016 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 ...

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.

Visual discomfort and blur [PDF]
, 2013 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 ...
