A pressure patch is achieved by placing two eyepads gently against the eye. The patient is then instructed to keep both eyes closed, while the pressure patch is taped firmly over the affected eye. The lower cheek should be pulled up firmly as tape is applied to keep the eye closed. The patch should remain on the eye for at least 24 hours, and follow-up by an ophthalmologist is indicated if the defect does not heal in 24 hours. A loose patch can do more harm than no patch, so care must be taken to ensure that the lids are securely closed under the patch.
