Help! I Made A Very Silly Mistake With My Contacts! Scared?!?

Okay, today i opened my contacts. I opened a Right box, but distracted by company i was in a rush and opened the OTHER right sitting in the box, instead of my left. My left and right are different powers.
Left: 3.50
Right: 3.75
BUT because my left eye has astigmatism, my optometrist pushed up the powers of my lens to:
Left: 3.75
Right: 4.00
She pushed up the powers because the astigmatism in my left eye isn’t bad so could get away with wearing normal coloured contacts (sorry i should have stated that. it’s hard to find coloured contacts that come with astigmastism).
So i went about my business wearing 4.00 in my left and 4.00 in my right. I couldn’t feel the difference but i don’t think it’ll be good in the long run… unless someone professional tells me it’s fine?!
What should i do?
If i open a left and throw away the other right i’ll be left with a useless left contact. If i continue with this for a month and the next month, open a PROPER pair, i’ll be left with 2 useless lefts. But i might be able to get 2 rights of 4.00. If i can?
Please help me! I don’t want these contacts to go to waste!

I Want To Have Lasik Surgery And I Am Scared. Please Tell Me If You Have The Experience With It.?

I have been wearing glasses even since I was a very young kid. I am highly nearsighted in my right eye and somewhat nearsighted in my left eye. I also have a high degree of astigmatism in my right eye. I never wore contact lenses. I want to lasik surgery because I don’t have to wear glasses again and have 20/20 vision but I am scared of the side effects. I am 22. Any advise on what to do. What do they do in lasik surgery? What is the procedure?
