Advances in adhesive hydrogels applied for ophthalmology: An overview focused on the treatment.

Abstract

Adhesive hydrogels, composed of hydrophilic polymers arranged in a three-dimensional network, have emerged as a pivotal innovation in ophthalmology due to their ability to securely adhere to ocular tissues while providing sustained therapeutic effects. The eye, with its delicate structure and specific needs, presents unique challenges for drug delivery and tissue regeneration. This review explores the transformative potential of adhesive hydrogels in addressing these challenges across a range of ocular conditions, including corneal injuries, cataracts, glaucoma, vitreoretinal disorders, and ocular trauma. By detailing the mechanisms of polymerization and adhesion, this paper highlights how these materials can be customized for specific ophthalmic applications, offering insights into their current use and future possibilities. The emphasis is placed on the clinical significance and future directions of adhesive hydrogels in advancing ophthalmic therapy, potentially revolutionizing the treatment of complex eye diseases.
