Monocular amblyopia and higher order aberrations [PDF]
Vision Research, 2012 This study compared the corneal and total higher order aberrations between the fellow eyes in monocular amblyopia. Nineteen amblyopic subjects (8 refractive and 11 strabismic) (mean age 30 ± 11 years) were recruited. A range of biometric and optical measurements were collected from the amblyopic and non-amblyopic eye including; axial length, corneal ...

Higher-Order Aberrations in Myopic Eyes
Journal of Ophthalmic & Vision Research, 2010 Purpose: To evaluate the correlation between refractive error and higher-order aberrations (HOAs) in patients with myopic astigmatism. Methods: HOAs were measured using the Zywave II aberrometer over a 6 mm pupil.

Peripheral refraction and higher order aberrations [PDF]
Australasian journal of optometry, The, 2020 Peripheral image quality influences several aspects of human vision. Apart from off-axis visual functions, the manipulation of peripheral optical errors is widely used in myopia control interventions. This, together with recent technological advancements enabling the measurement of peripheral errors, has inspired many studies concerning off-axis ...

Modern approaches to cataract surgery based on wavefront analysis
Офтальмохирургия, 2023 Relevance. Cataract is the leading cause of visual impairment worldwide. Even in the early stages of cataract development, when the maximum visual acuity often remains high, patients complain of a decrease in image quality (light scattering, diplopia ...
