Eye still puffy 15 months after fall - how can I improve this? (Photos)

Hello 40s white male good health . I had a bad fall 15 months ago landed on my eye on sidewalk. It was badly bruised and got a small linear flat scar that has since faded… but the puffiness did not get better . I had MRI 6 weeks after fall and nothing was broken . Report came back with soft tissue Edema in eye socket . I have since gone to eye doctors and derms and have been given zero guidance or treatment . Only 1 suggestion was possible it is lymphatic fluid and to use eye roller . It’s not hard and doesn’t hurt . Just puffy and when press on it it’s soft . Any thoughts ? Thank you
