Yes, it is a quite normal side effect from Lasik surgery. But every case is different, so I can't tell you how long exactly the blurry vision would linger longer after this surgery. Normally speaking, patients can go back home on the very day of operation, after about 3 hours staying in the hospital for further monitoring. But patients can't drive home for the blurry vision, so they should get others to help. In the first two or three days, patients can find their vision improved greatly. According to the skill of the surgeon and the complicity of the surgery patients taken, it might take 2-7days to restore a good vision, which is far much faster than PRK surgery. To get the best vision, patients need to be patient for at least six months. During this period, patients must provide good protection of the operated eye to avoid any damages or corneal scarring. Good luck.
