Bad outcome after eye surgery. HELP PLEASE!!!

I had the cataract removed/a lens placed, and I had worse vision and light blindness (the car lights blind me) and most lights have become very sensitive with halos around them.
They put new lenses in, and I wonder if they put them in backward? Or did they place them in at the wrong angle? I am terrified of the future because I am a CPA and cannot see the computer and numbers. I squint so hard that I end up with a headache. Can anyone lend some words of wisdom, PLEASE?

Thank you,
Catherine
