Can you have cataract surgery with posterior vitreous detachment (PVD),and floaters ?

There is a small increased risk of retinal detachment when you are over minus 5 or so. However, having the PVD already lowers that risk. If you are bothered by the cataract, you can't avoid surgery but will need dilated exams for the rest of your life (surgery or not) to check for tears.Some patients say the floaters are more bothersome if you have a multifocal lens so research that choice.Best of luck to you.

If the vitreous has completely separate from the retina (a complete PVD) the risk of complications from cataract surgery is probably not increased at all, as the retina is unlikely to tear if the vitreous is not sticking or pulling on the retina.  Changes in floaters are fairly unpredictable -- some people notice their floaters more because there's no cataract to block the view.  Other people notice floaters less because everything is brighter and clearer.
