Premium Intraocular Lens Selection in Patients With Glaucoma: A Clinical Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Glaucoma frequently coexists with cataract, but glaucomatous functional loss, ocular‐surface disease, anatomical abnormalities, and treatment‐related refractive variability may reduce tolerance of premium intraocular lenses. This narrative review critically appraises evidence relevant to lens selection in glaucoma. Central visual‐field status,

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Sex, Age, and Skull Morphology Effects on Eye Size and Refractive Errors in Reindeer

Ecology and Evolution, Volume 16, Issue 11, November 2026.
We tested the hypothesis that male reindeer (Rangifer tarandus tarandus) with larger skeletal dimensions, would have larger eyes and narrower binocular overlap, but similar refractive errors compared to females. After controlling for differences in skeletal measures, males were found to have relatively smaller eyes than females, whereas binocular ...

Focal ambient visual acuity stimulation improves vision in amblyopic children with stagnating BCVA—A retrospective study

Acta Ophthalmologica, Volume 104, Issue 7, Page 811-817, November 2026.
Abstract Purpose The aim of this study was to investigate whether amblyopic children with stagnating best‐corrected visual acuity (BCVA) would benefit from an additional stimulation therapy—specifically focal ambient visual acuity stimulation (FAVAS) integrated into a computer game—compared to occlusion therapy alone.

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

Advanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...
