Occasionally, during cataract surgery, the natural lens of the
eye (which is the cataract), or a portion of the lens, falls into
the vitreous cavity. This may cause inflammation in the eye
which can cause the normal pressure in the eye to rise to
dangerous levels. The dislocated lens can be removed by
vitrectomy surgery.
Another problem than can occur during or after cataract surgery
is the dislocation of the plastic lens implant, the intraocular
lens (IOL); the intraocular lens can fall into the vitreous
cavity. This can also occur following trauma to the eye.
Vitreous surgery can be done to place the plastic intraocular
lens in its proper position. The vitreous is removed and then
the lens is grasped with forceps and placed into position where
it may be sutured in order to keep it stable.
