Steroid Injection or surgery? Are steroids dangerous? (photo)

I'm super confused after reading so many conflicting opinions on getting a steroid injection vs surgery. 2 ophthalmologist i recently visited wants me to go for surgery. But I've had chalazions before and got steroid shots and worked like magic with no side effects. Are steroid injections really harmful? Some suggests that it can lead to cataract n glaucoma n stuff. I need some professional honest advice. Help!
