What are the side effects of eye laser surgery?
Disease description:
I am 28 years old this year. Due to prolonged computer use at work, my vision has gradually deteriorated, and I have finally decided to undergo laser eye surgery to correct my myopia. However, I am concerned about possible postoperative complications, especially dry eye syndrome and decreased night vision.

Laser eye surgery may result in post-operative complications such as dry eyes, refractive regression, and glare sensation.
1. Dry Eyes: Laser surgery involves cutting the sensory nerves within the anterior stromal layer of the cornea, which may damage the corneal nerves and subsequently affect tear secretion. Most patients experience gradual relief after surgery, although some may require adjunctive treatments such as artificial tears.
2. Refractive Regression: Some patients may develop myopic regression due to insufficient corneal thickness, excessive or improper eye usage after surgery, leading to secondary corneal expansion. Corrective glasses or a second surgical procedure might be necessary.
3. Glare Sensation: This is usually caused by the removal of excess corneal tissue during surgery, resulting in differing refractive powers between the central and peripheral areas of the cornea. Light entering the eye through these different corneal regions may refract and create scattered light spots.
It is recommended that you visit a reputable hospital and undergo these procedures under the guidance of a qualified physician to ensure surgical safety and stability. After surgery, it is important to closely monitor eye conditions, maintain good visual habits, avoid prolonged near-eye work, and schedule regular eye examinations.
