Tyrosine kinase inhibitors (TKIs) represent a promising category of therapeutic agents for managing edema and neovascular eye diseases (NEDs) such as corneal neovascularization, proliferative diabetic retinopathy and neovascular age-related macular degeneration. By impeding the phosphorylation of receptor tyrosine kinases, TKIs prevent the activation of angiogenic signaling pathways that are vital for cell growth and proliferation. However, the TKIs delivery in ophthalmology presents significant challenges such as toxicity and poor bioavailability. This review discusses emerging TKIs for NEDs, their physicochemical properties, and delivery systems, highlighting strategies such as sustained-release ocular implants, hydrogels, particulate and composite systems. Amid each category, we explore groundbreaking research approaches with a focus on preclinical and clinical studies, providing an in-depth look at the latest advancements in TKI-based delivery systems. Numerous TKI formulations currently under investigation (AXPAXLI, DURAVYU, CLS-AX and D-4517.2) hold the potential to improve therapeutic outcomes and enhance patient adherence, transforming the treatment landscape of NEDs. Advanced TKI delivery platforms, integrated with artificial intelligence-driven tools and minimally invasive technologies may enable more effective and personalized treatment options in the field of eye care.
