How can cataract surgery cause floaters and flashes of light?

ANSWER

Surgery can cause posterior vitreous detachment, where the vitreous separates from the retina. It makes you see moving spider webs and clouds in your vision, along with flashes of light.

Usually, it gets better on its own within a few months. Because the symptoms are similar to retinal detachment, call your doctor right away to get checked out.
