Please tell me how to reduce swelling

I had surgery on the 21st and my nose is fine, but my eye swelling is severe. I'm worried that if the swelling goes down late, my lines won't look pretty. What
 I'm doing right now
 is 1. Going for a walk
 2 Elevating the injured area
 3. Drinking pumpkin juice
 4. Eating pumpkin porridge and abalone porridge (starting on the 28th) (Change to regular diet)
 5. Take After Plus Bona Plus Slim 8
 6. Grind black bean powder and mix it with water like rice flour and drink it.
 7 I
 am drinking a lot of water. Please let me know if there is a good way to do anything else.
 I had my eye stitches removed yesterday. Afterwards, when I try to open my eyes clearly, there is some swelling and it is difficult to open them clearly.
 Can I try to force them to open, or should I just relax my eyes and keep going?
