Laser surgery is categorized into mainly eye surgery and skin surgery, and the hazards are different for different parts of the surgery. Eye laser surgery is mainly used for the treatment of myopia and other diseases. Due to the laser damage to the nerve endings of the eye, it will reduce the blinking reflex of the patient’s eye, and the tear secretion will become less, and the patient may experience discomfort symptoms such as dry eyes. Due to the cutting of corneal tissue, patients may also experience discomfort from glare and even postoperative complications such as eye infections. When laser surgery is performed on the skin area, there is a risk of postoperative side effects such as scarring, hyperpigmentation, postoperative thinning of the skin stratum corneum, skin sensitivity, and susceptibility to allergies. Although there is a certain risk of laser surgery, but choosing a regular hospital according to the individual’s physical condition for treatment, can try to minimize the risk of surgery. It is recommended that post-laser surgery patients follow the doctor’s instructions for care, regular review, and timely consultation when discomfort occurs.
