Blurry vision 3.5 months after LASIK, could this be due to dry eye?

had lasik 3.5 m ago. I was healing slower than normal. After 3 weeks I almost had clear vision. One morning after two month, my vision was so blurry. I saw doctor and they gave me Lotmax and Xiidra. my vision go better a bit but after 1.5 month of taking Xiidra and lotmax I still have blurry vison. It is a constant blurry vision and does not go away with blinking. They told me I do not have astigmatism or prescriptions but I have a real blurry vision. Is it dry eye? I am so worried it is HOA.
