Magnetic drug-loaded polymeric particles are used in a transscleral drug delivery method. In the synthesis process of the aforementioned magnetic drug-loaded polymeric particles, therapeutic agents, along with a magnetic agent are encapsulated in a polymer. The aforementioned magnetic drug-loaded particles can be placed near the outer surface of the sclera, and then a magnetic field can be applied in front of the eye to pull these magnetic drug-loaded particles to the outer surface of the sclera, where these particles adhere to the outer surface of the sclera and thus, the orbital clearance of the particles is eliminated or reduced.
