Should I be using eye drops after my blepharoplasty, what can I use to stop the puffiness? (photos)

Eyedrops can be used as needed. 
Frequently changed iced eyepads, a recumbant position, and arnica help with the puffiness in my experience. 

Thank you for your question and sharing your photos.  Swelling after surgery is variable, and healing can take up to three months or more.  Be patient and follow up with your doctors post-operative instructions.  I often have my patients continue using warm compresses to the lids daily until the swelling has resolved.  Best wishes.
