I can see a strange scary bright light in my pupil after cataract surgery. Any suggestions?

The acrylic material of the most commonly used intra-ocular lenses has this cosmetic side effect.
Some people call it "Terminator Eye".  The only way to get rid of this cosmetic issue is to exchange the lens for another one of different material. It's low risk but not now risk to exchange the lens. It's easier to do in the first few weeks after surgery and before Yag capsulotomy is done. 
Exchanges for cosmetic reasons are rarely done and usually not covered by insurance.

What you are seeing is likely the internal reflection of light from your intraocular lens. Clearly this will not disappear as long as the implant remains in your eye. Cosmetic concerns should be discussed with your surgeon.
