Post Lasik Healing

CVS pharmacy filled me glaucoma drops instead of anti-biotics for my post-Lasik Healing. Can I sue?
I guess the biggest question I have is if I still have time to. This occured in mid-July. The doctors at the center where I got the surgery called in the prescription. I got it filled the day before the surgery. After the surgery I was to take the drops to fight off infection. I got an infection and spent about 2 months fighting it with more (what I thought to be anti-biotic)drops, which were the glaucoma drops and other types. Finally one day my doctor saw them while I was rumaging through my purse and asked what I was doing with them. Then shock occured on both our parts.
I went to CVS and the senior pharmacist was the one who filled it! It simply stated he made a mistake. He was sorry.
So, can I sue even with the time delay?
You will need to be able to show damages.
