After effects of yag laser on eye?

Short lived floaters. The most common effect after yag laser capsulotomy for an "after cataract" is floaters and improved vision. The floaters should resolve within a few days. If you experience loss of vision, please let your doctor know.

Minimal. Yag laser is a cold laser used to divide membranes and tissues in the eye. It may be needed after cataract surgery to open a clouded membrane or in certain cases of glaucoma. If used for the former, floaters in the vision may occur for a time. If for the latter, a small amount of bleeding from the iris is common. Elevated eye pressure is an infrequent occurrence and easily treated. Pretty safe!
