Severe corneal injuries can cause visual impairment even blindness. Surgically stitching or implanting biomaterials have been developed, but their implementation requires professional surgeons, failing to address the immediate need of medical treatment. The pressing challenge lies in developing multifunctional biomaterials that enable self-management of corneal injuries. This study introduces collagen-based hydrogels that can be used as contact lenses, incorporating macromolecular collagen into common polymer materials via a dual-step orthogonal cross-linking process. This method ensures superior optical and mechanical performance while preserving the bioactivity and structural stability of the incorporated materials. Specialized contact lens facilitates the controlled release of labile protein therapeutics such as acidic fibroblast growth factor (aFGF), eliminating the need for stabilizers like heparin. This capability allows the lens to deliver a wide range of labile proteins, thus expanding its therapeutic use across various ophthalmic and potentially other medical conditions. The lens's anti-inflammatory and anti-fibrotic properties effectively treat corneal alkali burn. Termed 'corneal first-aids lens', it can provide postoperative clinical care and serve as a viable and safe therapeutic alternative for patients with limited medical access.
