A/an ____________________ is the removal of the vitreous humor and its replacement with a clear solution.

Vitrectomy is a type of eye surgery used to treat problems of the eye’s retina and vitreous. In this surgery, an ophthalmologist may:

remove blood or other substance keeping light from focusing properly on the retina
remove scar tissue that is wrinkling or tearing the retina and causing poor vision
help repair a retina that has detached (pulled away) from the eye wall
remove a foreign object stuck inside the eye from an injury

During vitrectomy, the ophthalmologist removes some or all of the vitreous from the middle of your eye. This vitreous is replaced with either a salt water (saline) solution or a bubble made of gas or oil.

During healing after surgery, your eye replaces the saline solution or the bubble with the natural fluid the eye makes called aqueous humor.
