Comparison of spherical and aspherical intraocular lenses with decentration and tilt error using a physical model of human contrast vision and an image quality metric [PDF]

, 2021
Purpose In this study, two intraocular lenses (spherical IOL SA60AT and aspherical IOL SN60WF) are examined in an eye model under conditions of misalignment (defocus, decentration and tilt).

Comparison of Positive Dysphotopsia Rates Between AU00T0, MX60E, PCB00/ZCB00, and SN60WF Intraocular Lenses

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the long‐term positive dysphotopsia (PD) rates associated with various intraocular lenses (IOLs) relative to the rates of PD associated with the Mx60E IOLs. Materials and Methods This was a retrospective cohort study design without randomization. Patients were selected by cross referencing lists of IOL implantations and ophthalmology

Acta Ophthalmologica, Volume 103, Issue 7, Page 764-775, November 2025.
Abstract To determine the incidence and identify risk factors of rhegmatogenous retinal detachment (RRD) following paediatric cataract surgery. This systematic review and meta‐analysis adhered to PRISMA guidelines and was registered in PROSPERO (CRD42024538383). A comprehensive search was conducted across multiple databases, including Cochrane CENTRAL,

Fluctuations in angle lambda with the pupil diameter and correlations with biometric values in a healthy population

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1837-1844, November 2025.
Abstract Purpose Angle lambda (λ) is defined as the angle between the line of sight and the pupillary axis at the entrance pupil. We previously developed a child‐friendly and portable method to measure this angle in daily practice. In a given population, angle λ fluctuates according to age or refractive error.
