After having cataract surgery, it is essential to follow your doctor’s instructions regarding covering the eye at night. Generally speaking, you should cover the operated eye with a patch or shield for one week following the procedure. The purpose of this is to protect your eye from any accidental trauma while you are sleeping and ensure that your healing process progresses normally. It may be uncomfortable or inconvenient at first, but it is important to keep the area covered until instructed otherwise by your doctor in order to prevent further complications after surgery. If you have any questions about how long you should cover your eye at night after cataract surgery, make sure to speak with an ophthalmologist who can provide guidance specific to your case and recovery plan.
