Changes in forward light scatter parameters as a function of refractive error in young adults [PDF]

open access: yes, 2020
Background/aims Some aspects of visual performance worsen with increasing myopia. Whilst the underlying causes are not always clear, reduction in retinal image quality is often attributed to structural changes in the posterior myopic eye.

Polycarbonate intraocular lenses

open access: yesJournal of Cataract and Refractive Surgery, 1988
Bisphenol-A polycarbonate has been investigated as an improved polymer for ocular implants, especially for intraocular lenses (IOLs). Polycarbonate properties afford special opportunities for development of tougher, stronger, one-piece IOLs. Autoclave or gamma sterilizability and a higher refractive index may provide additional IOL advantages over ...

Accommodating Intraocular Lenses

open access: yesAsia-Pacific Journal of Ophthalmology, 2017
With an explosive increase in the worldwide prevalence of presbyopia, development of an accommodating intraocular lens (IOL) with expansive accommodative amplitude remains the holy grail in lens-based refractive surgery. A dynamic change in the dioptric power of the eye can be accomplished by various strategies alone or in combination, including ...

Phakic intraocular lenses: An overview

open access: yesIndian Journal of Ophthalmology, 2020
Phakic intraocular lenses (pIOLs) are a common solution for the surgical correction of high myopia and myopia in thin corneas. Global trends result in increasing rates of patients with high myopia which will result in increased rates of pIOL implantation.
