Astaxanthin ameliorates benzalkonium chloride–induced dry eye disease through suppressing inflammation and oxidative stress via Keap1‐Nrf2/HO‐1 signaling pathways

Animal Models and Experimental Medicine, EarlyView.
The flowchart of this research. Abstract Background Dry eye disease (DED) predominantly results from elevated tear film osmolarity, which can not only cause ocular inconvenience but may lead to visual impairments, severely compromising patient well‐being and exerting substantial economic burdens as well.

Effects of customized corneal cross‐linking on higher‐order aberrations in progressive keratoconus and low‐grade myopia

Acta Ophthalmologica, EarlyView.
Abstract Objective To evaluate the effects of customized corneal collagen cross‐linking (CXL) on higher‐order aberrations (HOAs) in keratoconus (KC): vertical coma (VC), horizontal coma (HC), spherical aberration (SA), trefoil (TF) and astigmatism, compared with the same effects in healthy eyes undergoing CXL for low‐grade myopia.
