What are the symptoms of a recent posterior vitreous detachment?

Why do I have poor vision after vitrectomy?
The surgery involves making multiple cuts on the whites of the eyes. If these stitches are very close to the cornea, they change its shape causing blurry vision. If the vitrectomy was done to repair a large hole in the retina, the damage to the retina may not fully recover. Such vision loss may persist.
What else can be used to replace the vitreous humor?
There are three major categories of substitute: gases (air, expansile gases), liquids (salt solution, perfluorocarbon liquids, semifluorinated alkanes, silicone oil, etc.), and polymers (hydrogels, smart hydrogels, and thermosetting hydrogels) [15].
