Why did my vision worsen after pvd?

Need more info. In what way is your vision worse? Is it correctable with glasses or change in glasses? Are things blurry all the time or episodic? Do you see a large shadow? Do you see a lot of floaters? Pvd can cause bleeding in the eye, retinal tears or detachments which can all affect your vision. Theoretically your anatomy can mildly change and affect your vision refractively... Your eyemd can better answer.
