Hi. I'm online and happy to answer your question today. I am a retina specialist.
Are you available to chat?
I guess you have stepped away from your computer.
You are likely experiencing a PVD or posterior vitreous detachment, a common event that happens in many people.
You have a thick gel material in the middle of your eyes called the vitreous. Over time as it liquefies, this gel material collapses on itself, forms little clumps that you can see as dots, lines or bugs. As these clumps form the vitreous pulls away from the wall of the eye. In the process it can stimulate the retina -- causing the flashes that you may see. It is recommended that you see your ophthalmologist to look at the retina to make sure there are no problems such as a retinal hole or tear. In most cases, there are no problems, but this exam is precautionary and allows for preventative treatment of any lesions that are found. If you notice a sudden increase in floaters, flashes of light (like a lightning storm), or a shadow/veil in the periphery of your vision, this can be worrisome for a retinal detachment. You would need to contact your ophthalmologist promptly in that case.
A PVD can commonly occur after cataract surgery. This is particularly true if your surgery had any complications such as a tear in the posterior capsule with vitreous loss. If this had occurred your surgeon would have told you about it.
As long as you do not have any of the signs of a retinal detachment that I have mentioned above you should be OK. Since you recently had eye surgery, however, I would feel better if you gave your surgeon a call on Monday and had her take a look at you.
