1. Why did you take off your glasses?

Is this operation really necessary? Because surgery is usually minimally invasive eye surgery, although minimally invasive, it is a kind of surgery after all. If myopia surgery is not urgently required, glasses are preferred.

Are you suitable for this operation?

Strict examination is needed before operation, and doctors must strictly grasp the indications of this operation: if the patient's age should be between 18 ~ 50 years old, the myopia degree should be stable for more than 2 years, and the contact lens should be removed for more than 2 weeks, routine ophthalmic examination should be carried out before operation. Preoperative examination will find that patients who are not suitable for this operation, such as keratoconus, glaucoma, cataract, fundus lesions or systemic diseases such as diabetes, hypertension and collagen diseases, are all contraindications for surgery.

Do you know the changes of eyes after operation?

Refractive surgery only changes the corneal diopter, just like making a pair of biological glasses on the cornea, which has no preventive or therapeutic effect on other eye diseases. Some people may have insufficient correction of hyperopia and myopia, astigmatism, glare and other phenomena, so be patient and don't rush to re-operate.

4. Are you mentally prepared?

Have the desire to receive treatment to correct myopia and astigmatism, but don't have unrealistic expectations and don't set too high expectations for surgery. The domestic propaganda about becoming an "eagle eye" after surgery is just a gimmick and unrealistic.

The reason why human eyes are not "eagle eyes" is due to the special structure of human eyes. Of course, some friends in our hospital have corrected their vision to 2.0 or above after surgery, but this is a rare case, just like we yellow people are short, but Yao Ming is a giant in the world, and it is also a once-in-a-century situation.
