Kirigami‐Inspired Breathable Smart Contact Lens for Wireless Monitoring of Corneal Hypoxia and Microenvironment

open access: yesAdvanced Healthcare Materials, EarlyView.
A kirigami‐inspired breathable smart contact lens is reported for wireless monitoring of corneal hypoxia and microenvironment. The ultrathin (55 µm) and flexible sensing device enables digitalized, in situ and precise monitoring of dissolved oxygen, humidity, and temperature (R2 >0.98).

A Bioengineered Model of the Human Cornea for Preclinical Assessment of Human Ocular Exposure to Environmental Toxicants

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper presents a microphysiological system containing an array of individually addressable living corneal tissues constructed using primary human cells. The bioengineered eye model can simulate acute exposure of the human cornea to different types of environmental toxicants and provides a novel platform for visualization and quantitative ...

Dual‐Crosslinked Betaine‐Based Amphiphilic Hydrogel as a Promising Vitreous Substitute: Anti‐Adhesion, Anti‐Fouling, and Anti‐Cell Proliferation

open access: yesAdvanced Science, EarlyView.
A novel multiple cross‐linked betaine‐type amphiphilic polymer hydrogels are developed via in situ free radical copolymerization. The resultant formation, named P(SBMA‐co‐AANa) hydrogel, functions as a vitreous substitute and demonstrates superior performance in optical properties, support capacity, and biocompatibility on a vitrectomized rabbit model.

A Tailored Artificial Biocatalyst for Bacterial Endophthalmitis Therapy via Enhanced Ferroptosis‐Like Death

open access: yesAdvanced Science, EarlyView.
A tailored bio‐targeted catalytic strategy based on a bacteria‐specific artificial biocatalyst (MoS2/Fe@mercaptophenylboronic acid@hyaluronic acid, MFBH) is proposed for treating bacterial endophthalmitis. This strategy exhibits high‐efficiency peptidoglycan‐targeted bactericidal efficacy in vivo following a single intravitreal injection of an ...

Primary unilateral conjunctival small lymphocytic lymphoma in a child: Case report and literature review

open access: yesOman Journal of Ophthalmology, 2023
Ocular adnexal lymphomas (OALs) are extranodal lymphomas primarilyinvolving the ocular adnexa, which includes the conjunctiva. OALs are considered primary if the involvement of lymphoma is confined to the ocular adnexa alone and secondary if there is ...

Chirality Regulates Stem Cell Fate and Promotes Corneal Epithelial Regeneration via Manipulating Notch Pathway

open access: yesAdvanced Science, EarlyView.
Chirality governs the limbal epithelial stem cell fate. Right‐handed chirality enhances cell proliferation and differentiation, while left‐handed chirality partially maintains cell stemness. By activating the Notch pathway, 3D right‐handed chiral hydrogel offers a drug‐free and cell‐free strategy for effective corneal regeneration.
