It is important the dog does not rub the eye whilst the eyelid is healing, or they could dislodge the sutures and cause the wound to open up. Wearing a cone for the duration of the recovery period is usually sufficient to prevent this.
Given the difficult nature of the removing sutures from the eyelid, the surgeon usually uses an absorbable suture material which dissolves of its own accord. It takes around 7 - 14 days for the eyelid to heal, which most surgeons, erring on the side of caution, suggest keeping the cone on for 10 - 14 days.
It is common for the eyelid to swell in the days following surgery, but this usually subsides uneventfully. The dog may be given pain relief to take at home for the first few days following surgery, but in most cases, antibiotics are not required.
Once the eyelid has healed, there should be no recurrence of the lump at that site, however 'de novo' or new, unrelated lumps, may grow at some point in the future.
