Nano Biomaterials for Ophthalmic Drug Delivery: A Comprehensive Overview of Current Advancements and Future Prospects

Ophthalmic drug delivery is a challenging task due to the unique anatomy and physiology of the eye. Conventional eye drops are often inefficient due to poor corneal penetration, rapid tear turnover, and enzymatic degradation. Nano biomaterials have emerged as a promising solution to these challenges, offering controlled drug release, targeted delivery, and improved bioavailability.
