Well, according to the eye doctor, it will take about 3 months to recover your eyes after prk surgery. In the first 2weeks, it is very normal for you to have the blurry vision. So you should not worry about it at that time. And then the next 2-4 weeks, there is more rapid improvement of your vision. Finally, the more gradual improvement will come in the following 2 months. So you should be careful in this period. Since the eyes after surgery are very sensitive and fragile, you should pay more attention to avoiding the infection. For example, you should avoid eye injuries by wearing a protective shield at night and with naps until you are advised by your doctor. Also, you should remember not sleep on the side of the operated eye for the first night.
