After the anaesthetic is administered, your eye and face will be covered with a sterile drape. The whole vitrectomy operation will then be performed through 3 tiny incisions. You will hear vibrating noises throughout much of the procedure from the vitrectomy machine. You will not be able to see details of what is happening but may see only shapes or bright lights, or nothing at all. The operation will last from between 20-40 minutes. At the end of the procedure I routinely administer some antibiotics and antiseptic to minimise the chance of infection in your eye. I will then place a protective eye pad to shield your eye overnight. I will fully inform you of the posturing instructions and you will then be able to return to the eye clinic or ward.
