Corneal neovascularization (CNV) can induce severe visual impairment and even blindness. Current treatments have limited efficacy and some undesirable side effects. Phototherapy (PT) is a modern medical technique in CNV treatment and worth further improvement. Nanotechnology has various advantages and nanoparticle-mediated drug delivery also contributes to CNV elimination. Phototherapy combined with functional nanoparticles featuring photoacoustic imaging contrast properties can accomplish accurate and safe inhibition of CNV, thus is promising in clinical application.
