It seems from the history that you had underwent catarct surgery in both the eyes. One eye had probably peribulbar hemorrhage during anesthesia
before surgery because of injury to a blood vessel.
Flickering of the eye which is seen now is not related to the event which occurred two months back during surgery. Flickering of the eye is called as blepharospasm
and is usually because of spasm of orbicularis oculi muscle
of the eye lid which is supplied by facial nerve
If the problem is persisting, I advice you to consult your ophthalmologist for examination and treatment accordingly.
