ABSTRACT:
The present invention comprises viewing devices for use by those who must maintain a head down position, such as those who have undergone a surgical procedure for reattachment of the retina or repair of a macular hole, wherein a gas bubble is injected into the eye. The bubble, which is used to maintain the juxtaposition of the healing tissues, applies pressure upwards. If the surgical site is at the back of the eye, the postoperative patient needs to maintain a facedown position, for the bubble to maintain the retina against the back of the eye until the tear, detachment or hole is mended.
