Almost every patient will suffer from the dry eyes after lasik surgery, Which is a quite normal phenomenon. Because under normal conditions, the very sensitive nerves in the cornea send signals to the Lacrimal Gland that produces tears in response to dryness or irritation. In order to eliminate your nearsightedness or farsightedness, the surgeon need to shape the cornea by preparing a thin flap with the Lasik energy. And during the creation of the flap, some of the cornea nerves will be temporarily damaged. That is to say, for some time after your LASIK, the regular nerve impulses that used to tell the Lacrimal Gland to produce tears will be interrupted. That is why people suffer from dry eyes after LASIK. Usually in 2 weeks at least and 1 year at most, people will get relief if they take measures correctly as they are instructed by the doctor. Like use eye drops , wear sunglassses when being outside.
