After vitrectomy, I feel that there is always water moving in front of me. What's going on?

1.

Silicone oil is

often filled during vitrectomy in

order to stabilize intraocular pressure. If too much silicone oil is filled and the silicone oil is not absorbed, this symptom may occur.

2. When the

lens or aqueous circulation structure of the eye is damaged during surgery, it may affect the aqueous circulation, resulting in water ripples and blurred vision.

3. When

retinopathy occurs after surgery, the retinal structure is easily affected. At this time, fluid flow symptoms will appear in front of the eyes, and usually cannot recover by itself.
