Why do I still have myopia after lasik?

I had a lasik surgery two weeks ago. I still see blurry especially in my right eye.The blurr is very noticeable that I cant see clearly from a distance or make out words on the computer without squinting.I asked for my doctor forthe reason.He examined me and tald me that I still have myopia L -0.5&R -0.75.He gave me a priscription eye glasses and tald me thatafter 3 months he can do an enhacement surgery if my sight didn't clear on it's own.But also mentioned that my eye sight might even get worse.
