Is the effect of Xi'an ophthalmic laser surgery lasting?
Ophthalmic laser surgery is a common surgical method to correct myopia, hyperopia and astigmatism. However, many people have doubts about whether the effect of laser surgery is lasting. In Xi'an, there are some professional ophthalmic hospitals that provide ophthalmic laser surgery services. The following four aspects will be described in detail to answer this question.

Principle of operation
LASIK and PRK are two kinds of laser surgery techniques used in Xi'an Eye Hospital. LASIK changes the shape of the cornea by cutting the inner layer of the cornea with a laser to improve vision. PRK uses laser to cut the corneal surface directly to remove myopia or astigmatism.
Laser surgery changes the refraction of the eyeball, focusing light on the retina, thus improving vision problems. This change is lasting, and obvious effects can be seen within a few days after the operation.
Postoperative effect
Laser surgery in Xi'an Eye Hospital can significantly improve vision problems, and many patients after surgery can significantly feel the improvement of vision. After surgery, patients generally do not need to wear myopia glasses or vision correction tools.
However, it takes some time for vision to recover after surgery. Some patients may have dry eyes, halos and night vision problems within a few months after surgery, but these problems usually improve over time.
Key to maintaining effect
The key to maintain the effect of surgery lies in postoperative nursing and standardized living habits. Patients need to visit again regularly and follow the doctor's advice for eye care. In addition, avoiding excessive eye use for a long time, keeping enough sleep, and avoiding eye injuries are also key to maintaining the surgical effect.
In addition, because the eyes will still change with age, some patients may need multiple operations to maintain the effect.
Summary
The effect of Xi'an ophthalmic laser surgery is lasting. The shape of cornea can be changed through laser surgery to improve vision problems. After surgery, patients can obviously feel the improvement of vision and no longer need to wear vision correction tools. The key to maintain the effect of surgery lies in postoperative nursing and standardized living habits. Although the effect of surgery is lasting, patients still need to return regularly and keep their eyes healthy to maintain the stable effect of surgery.
In a word, Xi'an ophthalmic laser surgery has a remarkable and lasting effect on improving vision. The patient should consult the doctor carefully before the operation, and strictly follow the doctor's suggestions and postoperative nursing guidance to ensure a good duration of the operation effect.
