Lower eyelid surgery 8 days ago. Is this goopy fluid normal? Chemosis? (Photo)

Hard to tell from this photo, but if you have what appears to be a blister or fluid over the white part, this is chemosis.  This is a back up of fluid most likely due to a reduction of the normal lymphatic drainage from the eye after the surgery.  It may occur in up to 25% of cases.  It will resolve.  Use a lot of lubricant drops.  And the tobradex may help.  Your chemosis is very mild so should resolve quickly.  Look like you are healing well and will have a nice result.  

This can be a fairly common occurrence. The ointment is helpful along with protection of the eye so that it does not continue to be irritated and inflamed.

Occurs in 25% of cases to differing degrees. Continue with your surgeon but see a eye doc OK also....

Swelling development of the conjunctiva (clear surface of eye) can occur quite frequently.  It is usually temporary and easily treated with topical steroid eye drops, massage, and keeping the ocular surface moist (drops, ointment, gel).  It is more common when lower eyelid skin is incised as this can alter the lymphatics around the eyes cause the build-up of fluid on the eye surface.  If, however, you are having a green-yellow discharge then you may have a bacterial conjunctivitis.  Getting the swollen fluid (chemosis) to resolve sooner than later is important to avoid it becoming a chronic issue.  I would suggest discussing with your surgeon.  Best regards.
