Hi, I had SMILE surgery for my eyes around 6 months back. Earlier my vision is correct for 1 month but then my vision got blur for right eye and when i got it checked, doctor said it will get corrected by eye drops only. Since then i am continuously using eye drop but i still have blurred vision , so will it remain like that only? Moreover i was prescribed "HYDRY"eye drop and it is about to finish and because of lockdown it is not available at nearby stores or online.. So can i use "Refresh tear" instead of that if there is no side effects.. Please help and let me know if my vision can be corrected using medicine(since it's already six months) or i need to undergo surgery again? Thanks in advance!!
