What are the pros and cons of laser eye surgery?
Disease description:
I am 35 years old this year, and due to prolonged work in front of a computer screen, I have developed some degree of myopia. I am considering laser eye surgery to improve my vision, but I don't know the advantages and disadvantages of this procedure. Could you please explain them to me?

Laser eye surgery is a modern medical technique widely used for correcting myopia, hyperopia, and astigmatism. It primarily reshapes the cornea using a laser to adjust the eye's focusing ability, allowing light to correctly focus on the retina and thereby improving vision. Advantages of laser eye surgery include high precision, high surgical safety, short operation time, and significant results. However, possible disadvantages include dry eye syndrome, vision regression, glare, and halos.
The procedure is highly accurate, enabling precise control of laser dosage and intensity to correct vision problems accurately. It is also very safe, as it does not cause permanent damage to the cornea, and recovery after surgery is typically fast, allowing patients to return to their normal lives in a short time. The surgery is quick and simple, does not require hospitalization, and offers great convenience. The visual correction effect is remarkable, enabling patients to be free from glasses or contact lenses after surgery, thus improving their quality of life.
Some patients may experience dry eye syndrome after surgery, characterized by symptoms such as dryness and a foreign body sensation in the eyes. In addition, vision regression can occur, possibly due to corneal remodeling during the healing process or poor visual habits after surgery. Some patients may also experience visual phenomena such as glare and halos, which are more noticeable at night or in low-light conditions. There are indications and limitations for the surgery, meaning not all patients with refractive errors are suitable candidates.
Patients are advised to choose experienced ophthalmologists and well-equipped medical facilities. Prior to surgery, patients should fully understand the surgical process, expected outcomes, and potential risks, and should have detailed discussions with their doctors. After surgery, patients should follow medical advice, attend follow-up appointments regularly, maintain proper eye hygiene and protection, and avoid strenuous physical activities and contact sports until the doctor confirms satisfactory recovery.
