Intraocular light scatter as modeled through a stratified medium [PDF]

, 2001
Intraocular light scatter is modeled through a stratified medium. It is shown that the eye lens possesses properties of an interference filter. In conditions that may mimic opacification, as found with cataract formation, such a filter may have stop ...

Acute clouding of trifocal lens during implantation: a case report

BMC Ophthalmology, 2017
Background Intraoperative IOLs clouding of several kinds of hydrophilic acrylic intraocular lenses (IOLs) have been reported due to temperature changes. This phenomenon reported previously occurred in cold countries and during the winter months. However,

A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

Acta Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Association Between Lens Thickness and SRK/T Refractive Prediction Error After Cataract Surgery: A Single‐Center Retrospective Cohort Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To evaluate the association between lens thickness (LT) and SRK/T refractive prediction error following cataract surgery and to analyze its underlying mechanism. Methods This retrospective cohort study collected data from patients who underwent surgical treatment for age‐related cataracts between January 2025 and June 2025.
