On another group, a member posted a message claiming that he had had two
vitrectomies in the same eye. Once the vitreous is removed, it never
regenerates, does it? Then how is it possible to have two such procedures
in the same eye (for diabetes, in that case)?

The air is replaced by a bodily fluid (simple water? phlegm? lymph?), or the
doc fills the eyeball with water himself.

The first vitectomy may have left some of the "skirt" anteriorly at the edge
of the retina. In some cases this later causes traction, and needs to be
removed, in a second vitrectomy. So, no, the portion of the vitreous removed
before does not regenerate, and the eye at hat point is mostly filled with
aqueous humor.

This skirt is sometimes not entirely removed orginally as it means indenting
the globe to see it and remove it, and it is move involved that a more
simple vitrectomy. Also, some areas of scar tissue may have stayed behind on
the surface of the retina posteriorly, and removing that is often times
referred to as a vitrectomy again.
