Nursing staff will put an eye drop in your eye to enlarge the pupil in one or both eyes. It may blur your near vision. You are advised not to drive following this treatment or go home unaccompanied. Once you have agreed on the treatment, you will be asked to sign a consent form giving your permission to the laser treatment. You may be invited to attend a laser treatment course. You may eat or drink as normal and take your insulin dose or diabetic medication.
