摘要:
The present invention relates to a method for manufacturing a hollow microneedle for subretinal injection or extraction. The microneedle for subretinal injection or extraction is made of metal, thereby providing the strength and force for penetrating the sclera and retina. Due to the length and the angle of curvature, the microneedle for subretinal injection or extraction of the present invention can reach a suitable subretinal site, such as the midperiphery at which optic nerves are accumulated, and thus the present invention is effective for delivering a drug and can enhance the effectiveness of the drug.
