Understanding higher‐order aberrations in keratoconus

ABSTRACT Keratoconus is characterized by progressive thinning and increasing irregularity of the cornea, leading to substantial degradation in optical quality through the induction of both lower‐ and higher‐order aberrations (HOAs). In addition to inducing myopic and astigmatic r...

The effect of 0.1% topical ciclosporin a for 12-weeks on the ocular surface innate and adaptive immune response in dry eye disease: protocol for a randomized controlled clinical trial

Background Ocular surface immune cells and pro-inflammatory cytokines have been reported to be increased in Dry eye disease (DED). Immunosuppressive agents such as topical cyclosporine A (CsA) can inhibit dendritic cell and T cell activation. However, CsA’s impact on ocular surfa...

Interactions between hippocampus and visceral organs in sleep and wakefulness

Abstract Exteroception is attenuated during sleep, while interoceptive signals may remain active. If so, they can trigger responses in their target areas, including the hippocampus, which is known to receive information from the internal organs and is susceptible to oversynchroni...

Functional vision and symptoms associated with prolonged digital device use in astigmatic contact lens wearers

PURPOSE: Prolonged digital device use can result in digital eye strain which may be exacerbated by uncorrected astigmatism. This study explored how sustained smartphone reading impacts on visual function and symptoms when astigmatism is corrected with disposable soft toric contac...
