High heart rate after cataract surgery

I had cataract surgery on my left eye one week ago. I have been taking my drops and not doing anything I am supposed to do. As of yesterday I started noticing that my heart rate has been in the 90s and the low 100s. I don’t know whether it has anything to do with the cataract surgery or the drops. I have never had it go that high. Is that happened to anyone else?
