Wear the plastic shield(s) or goggles every night for the next 5 nights. This prevents you from rubbing your eye(s) while sleeping. For the first two weeks following surgery, wear sunglasses when you are outdoors, even when it is cloudy. If your eyes are matted in the morning, hold a warm washcloth over your CLOSED eyes for about 60 seconds to loosen matter. If this does not loosen enough to gently remove matter, apply washcloth for another 60 seconds. Use the corner of the cloth to gently clean the corners of the eyes. Then you can begin your medicine drops and lubricant drops for the day. Avoid atmospheres that may irritate the eye(s) such as smoke, dust, and other potential irritants. Dusty work environments may require safety glasses for protection.
