It is important to keep cold compresses on the eyes the first 48 hours after surgery. Do not use an ice bag. It is also important for you to keep your head elevated the evening after surgery as well as for the first two weeks following surgery. This can be done by either sleeping in a recliner tilted at 45 degrees or sleeping with two pillows underneath the head. Avoid rolling onto your face.
Sleeping on your back for the first two weeks after surgery helps to ensure this.
