It's impossible for anyone here to tell what is actually causing your blurred vision. As Dr. Oyakawa says, you may need an additional LASIK enhancement. If it's dry eye, some dry eye symptoms are chronic, and some lessen or go away over time. I would strongly encourage you to get a referral from your optician to an ophthalmologist.
by using this medicines will my problem get solved how much long should i use these medicines i hav been prescribed to use it for a month
Your optician is treating you for symptoms of dry eye. Restasis is a commonly prescribed drug that aids in tear production, and Optive is an over-the-counter (at least here in the U.S. it is) artificial tear / eye lubricant. If these aren't helping, then you may want to get a second opinion from an ophthomologist (eye MD).

i asked my doctor but he is saying ur vision is perfect 20/20 i dont know y he is not accepting that i hav problem
You probably need an enhancement.
