After vitrectomy for retinal detachment you will be advised to posture for a few hours looking down towards the floor (prone positioning). After that, the instructions for posturing will depend on the location and number of retinal breaks found during your operation. Posturing, if required, will typically be for 7 days. Instructions will be given in full by myself at the end of your procedure. Posturing is ordinarily not required after a scleral buckling procedure.
