What are the potential hazards of laser surgery for nearsightedness?

Hazards of Laser Surgery for Myopia

The hazards of laser surgery for myopia primarily encompass decreased visual quality, dry eye syndrome, corneal flap displacement, infection, and more. It is advisable for patients to undergo treatment under the guidance of a physician. Here are the details:

1. Decreased Visual Quality

Laser surgery for myopia involves using excimer laser to reshape the corneal tissue, thereby correcting vision. If the patient has a high degree of myopia and a relatively thin cornea, postoperative visual blurriness may occur, sometimes accompanied by symptoms such as dizziness and nausea.

2. Dry Eye Syndrome

Since laser surgery for myopia requires cutting through the corneal stroma, postoperative dry eye symptoms are common. This is generally a normal physiological response that can be alleviated by drinking more water or using artificial tear drops, such as sodium hyaluronate eye drops or polyvinyl alcohol eye drops.

3. Corneal Flap Displacement

Improper handling by the surgeon during laser surgery for myopia may lead to displacement of the corneal flap, adversely affecting the surgical outcome.

4. Infection

Individuals with low immunity who fail to maintain proper eye hygiene after laser surgery for myopia may be prone to bacterial invasion, potentially resulting in conjunctivitis, keratitis, and other ocular diseases, adversely impacting overall health. Besides, hazards like keratoconus may also arise.

It is crucial for patients to seek prompt medical attention and receive appropriate treatment under the guidance of a physician.
