Of course, lasik surgery not only can correct farsightness but also near-sightedness and astigmatism. Although the procedure is considered safe and effective, there can be some temporary side effects. After surgery, patients' sight is blurry and there may be discomfort. Eyes can feel gritty and this is eased using eye drops. Some patients experience hazy caused by eye secretions but this does resolve itself after a few days to weeks. Night halos are also common after surgery making night driving difficult. But most halos are reduced significantly after the swelling goes away. Rare complications such as a wrinkle in the corneal flap or a raised central island may require further surgery but these side effects are very rare indeed.
