Loss of vision in both eyes for a second happened twice had headache in temples at the time have had catarac s removed 5 years ago?

See eye doc: See eye doc for full exam. It is odd that it happened in both eyes at the same time. It may indicate a problem in the part of the brain that interprets vision such as a tia/stroke.

Ocular migraines: Your episodes are pretty brief, but ocular or eye migraines can occur in both eyes at once. Tia (mini stroke) can also do this, so see your medical doctor!
