Tiny bumps after eyelid surgery are normal and usually resolve on their own within 3-4 months as scar tissue matures. They can be due to lymphatic fluid, scar tissue, suture reactions, or deep sutures near the bone. Leaving bumps untreated is usually best unless they are infected, in which case warm compresses and antibiotics may help. Following up with a surgeon is important to determine the cause and best treatment if needed.
