Kobayashi (a pseudonym) lay on the operating table, trembling, and sweating. In order to alleviate his nervousness, he simply sang the song ... The main doctor Ma Fei looked at Kobayashi like a small motor. The eyelids, patiently comforted: "Don't be nervous, it's just a myopia correction surgery, just a few minutes!"

Many friends around him, like Kobayashi, eager to take off the glasses, but were afraid of myopia correction surgery. After all, it is a knife on the eyes. Can you do it? Will there be sequels? Recently, "Li Live · Famous Doctor Inverse" specially invited Ma Fei, director of the Ophthalmology Center of Jiangsu Provincial People's Hospital, Ma Fei as a guest live broadcast room to answer your questions.

Surgery cannot cure myopia!

Before the myopia correction surgery, we must understand that although this operation can help us improve naked eye vision and remove glasses, it does not mean that it is nearly visual cure. The structural changes brought by myopia cannot be reversed, especially the risks of various complications brought by high myopia still exist. As far as the current medical level is concerned, once myopia cannot be cured, myopia prevention and control must not be slacked.

Preoperative examination is important!

In theory, the number of myopia is 50 degrees -1000 degrees, the astigmatism degree is 50 degrees -500 degrees, and patients aged 18-45 meet the preliminary conditions for myopia correction surgery. In addition, detailed preoperative examinations are required before myopia correction surgery, including comprehensive optometry, corneal morphological examination (including thickness), visual quality examination, bottom examination, and systemic disease screening. Only through comprehensive and fine preoperative screening can doctors accurately determine whether the patient can perform myopia correction surgery can the risk of surgery be minimized.

C contact will affect our eye watches more or less, and pre -operation examination hopes to obtain the most primitive and most authentic data, so before surgery, we must completely stop these contact lenses, including these contact lenses, including Ordinary soft contact lenses, hard oxygen cornea contact mirrors (RGP) or cornea shaping mirrors. Among them, soft contact lenses need to be stopped for 1-2 weeks, RGP hard contact lenses need to be stopped for more than 1 month, and corneal shaping lens needs to be stopped for more than 3 months.

Which surgical method is good?

In terms of surgery, myopia correction surgery can be roughly divided into two categories. One is corneal refractive surgery, that is, the laser surgery we usually call; the other is crystal refractive surgery. Corneal refractive surgery is mainly to flatten the corneal central area through laser, thereby changing the refraction path of the light to achieve the purpose of correction myopia and astigmatism. Generally, surgery can be completed in 5-8 minutes.

Corneal refractive surgery has high requirements for corneal thickness, curvature, and morphology. The crystal refractive surgery is implanted between the iris and the crystal of the eyes, as if wearing an invisible eye inside the eyes. Crystal refractive surgery has high requirements for the space in the eyes, and it is also an ideal choice for patients such as high degree or thin cornea. What kind of surgical method is suitable for the specific patient, which needs to be combined with their own needs and preoperative examination results to choose from the guidance of a professional doctor.

Postoperative review cannot be less!

Most patients will recover quickly after surgery, but there are also a few patients with foreign body sensations, tears, bloating, and slow vision recovery in the early stage after surgery. Therefore, it is important to review on time after surgery. Generally, at least three reviews must be performed after surgery. The first review is the first or second day after the operation. The second review is one week after the operation. It was a month after the operation. Through these three reviews, doctors can basically grasp the patient's response to surgery and postoperative recovery.

In addition, it should be reminded that within 3-5 days after surgery, you still need to use less eyes, try not to use electronic products as much as possible, and let your eyes rest more. Will surgery cause dry eye?

Taking corneal refractive surgery as an example, in rinse, disinfection and surgical operation will inevitably affect the cornea epithelium. The scanning of laser will cut off the nerve ending of the part, causing dry eye symptoms. For this type of patients, the use of artificial tears can help the eye watch recovery faster and better. Generally, the symptoms of dry eye symptoms will gradually disappear after two to three months after surgery. It should be noted that for patients with dry eye before surgery, it must be treated with standardized treatment and review before surgery.

Will surgery cause night blindness?

The decline in vision after myopia correction surgery may be related to the size of the surgical area and the unevenness of the inter -cornea structure, which will slowly recover after a period of time. Night -blindness is caused by dysplasia or lesions in the retina responsible for night vision, and the two are completely different.
