The mechanism of presbyopia

Progress in Retinal and Eye Research, 2005
Accommodation in humans refers to the ability of the lens to change shape in order to bring near objects into focus. Accommodative loss begins during childhood, with symptomatic presbyopia, or presbyopia that affects one's day to day activities, striking during midlife. While symptomatic presbyopia has traditionally been treated with reading glasses or

Prandial Presbyopia

Journal of Neuro-Ophthalmology, 2010
Loss of accommodation amplitude during eating (prandial presbyopia) is a rare phenomenon that has been reported in only 1 patient who had had head trauma. We report 2 patients who had not had head trauma and whose accommodative amplitudes, measured by dynamic retinoscopy, became markedly diminished within 1 minute of starting a meal and did not recover

Accommodation and presbyopia

Ophthalmic and Physiological Optics, 1995
Summary The mechanism of accommodation has been studied for at least four hundred years. The most interesting aspect of accommodation is that its time course is well in advance of other physiological functions – it begins to decline by adolescence and is lost about two‐thirds of the way through the normal line span.

Pharmacological Treatments for Presbyopia

Drugs & Aging, 2023
Accommodation is the change in dioptric power of the eye. It is a dynamic process that allows focusing on an object at all distances. In order to focus sharply, three physiological responses, known as the triad of accommodation, are produced by a change in pupil size, a change in shape and position of the lens, and ocular convergence. This is modulated

Revisiting monovision for presbyopia

Current Opinion in Ophthalmology, 2018
Presbyopia is an inevitable age-related loss of accommodation that results in spectacle dependence with common everyday near-vision tasks. Many surgical approaches to presbyopic correction have been investigated, with monovision correction being amongst the most common and attractive options.
