Eyelid reductions for the upper lids, are usually carried out under a local anaesthetic with or without sedation (where the whole area is numbed with injections and you are awake but sedated to keep you calm).
The operation usually takes one to one and a half hours.
You might be given antibiotics to keep the wound clean.
You will go home the same day and a responsible adult should stay with you for the night. You may have an eye pad placed over both eyes so will need to be looked after for the first night.
Simple painkillers should be enough to keep you comfortable.
After the surgery you should not drive or use machinery for at least 24 hours, until you have recovered feeling, movement and co-ordination.
It is common to have watery eyes after an eyelid reduction, partly because of swelling under the conjunctiva (the membrane that covers the front of the eye and lines the inside of the eye socket) and partly because the tear ducts are swollen and do not drain properly. This will last a few weeks. Your surgeon will give you eyedrops to help to ease the feeling of grittiness. After surgery, the eyelids might look and feel tight when closed because of the swelling and because skin has been removed. If you cannot completely close your eyes at night you should apply some eye ointment before going to sleep. This tightness will ease as the swelling goes down.
