Vitrectomy surgery
Vitrectomy is a procedure to remove part of or the entire vitreous humor to create better access to the retina allowing for the treatment of retinal diseases.
​
Vitreous humor is a transparent gelatinous mass between the lens and the retina that fills 80% of the eyeball space. It acts to transmit the light rays from outside to the retina, providing nutrients for the lens and retina. It also creates pressure to fix the lens shape, helping the lens to focus a sharp image on the retina. The vitreous humor is formed from one’s birth, stays forever, and should not be replaced, except by human action (Vitrectomy) if needed.

Therefore, it is not possible to guarantee the postoperative results with certainty. The post-operative vision can be improved, but very little, or cannot.
Vitrectomy is intended for:
