Abstract:
A system of head rests is disclosed for use by patients convalescing from optical surgery to re-attach a detached retina. In this procedure, a bubble of air is injected into the affected eye, and the patient is instructed to keep his or her head in a face-downward position for eighteen hours a day during a convalescent period in which the air bubble presses the retina against the back wall of the eyeball. A day-time version of the apparatus is adjustable in height and preferably incorporates armrests and a plurality of mirrors so that a person who has his face turned toward the floor may view television or may make eye contact with another person. A night-time version of the apparatus allows a person to lie in a prone position with his or her head supported above and out of contact with the mattress, and preferably includes a viewing window so that a prone patient can read a book placed on the floor.
