摘要

The present invention relates to a self-sealable injection needle for inhibiting formation of fistula on an eyeball, and a method for manufacturing same. More specifically, the self-sealable injection needle for inhibiting formation of fistula on an eyeball, which is coated with hyaluronic acid on the surface thereof, can immediately close a hole that is inevitably formed when the injection needle is pulled out of an eyeball during the application of an ocular injection to prevent leakage of aqueous humor and to prevent backflow of drug out of the eyeball and can block bacterial penetration to prevent infection in the eyeball.
