After laser eye surgery, patients may suffer from common complications such as dry eye, glare, and rare complications such as cone cornea, which are all risks of laser surgery. 1. Dry eye: patients because of laser surgery on the corneal tissue cutting, will have a certain impact on the corneal surface of the tear film formation, etc., tear film is destroyed, resulting in patients can appear dry eyes, foreign body sensation and other symptoms of dry eye discomfort. 2. Glare: Due to the limited cutting area of the cornea by laser surgery, in the environment with poor lighting conditions such as at night, the pupil is dilated, and the patient may experience discomfort such as glare, which may cause a decrease in the quality of vision. 3. Conical cornea: some patients with insufficient corneal thickness and myopia are large, after laser surgery, the remaining corneal tissue is too small, and the cornea puffs out forward into a conical cornea. It is recommended that post-laser eye surgery patients follow the doctor’s instructions for care, regular review, and timely consultation after discomfort occurs.
