It is said that myopia will disappear from the world

Abstract: at present, there are two kinds of myopia treatment surgery: one is excimer laser surgery; The other is posterior chamber refractive intraocular lens implantation, which is often called refractive lens surgery. Refractive crystal surgery is called “addition surgery” in the industry, and excimer laser surgery is called “subtraction surgery”., Recently, a message “there will be no myopia in the world in 2017” exploded in the circle of friends. According to the article, a Canadian company has successfully developed a bionic lens, which can not only correct poor vision, but also better than 1.0 vision. This technology is being recognized by the national government and will be available as soon as 2017., In recent years, news about myopia surgery is emerging one after another. Many people choose to have surgery in order to take off their glasses, because it only takes more than ten minutes to help myopic people have bright eyes again. Can myopia be cured? Authoritative ophthalmologists will clarify common questions about myopia surgery., There are four conditions for myopia surgery. Myopia is a common eye disease, which has a great impact on vision. According to the survey of the Ministry of education and the former Ministry of health, the myopia rate of primary school students in China exceeds 25%, that of junior middle school students is nearly 70%, and that of senior high school students is 85%. The myopia rate increases at a rate of 8% every year, ranking first in the world., Liang Ge, director of Ophthalmology of the Second Artillery General Hospital of the Chinese people’s Liberation Army, said that now, The most common method to treat myopia is excimer laser correction surgery (hereinafter referred to as “laser surgery”) )However, many people know little about this kind of surgery, and there are some misunderstandings., Myopia is caused by long anterior posterior diameter of the eyeball, too convex cornea and inaccurate convergence of external light in the fundus. Laser surgery for myopia is to use the laser beam to change the curvature of the anterior surface of the cornea to correct ocular ametropia. Generally speaking, it is to “grind” a pair of appropriate glasses on the cornea, so that the external light can accurately converge and image in the fundus, so as to achieve the purpose of correcting myopia., There are four conditions for laser surgery. Not all people with myopia are suitable for excimer laser correction, which mainly depends on the state of the eyes. Generally speaking, four conditions can be met: 1 At least 18 years old; 2. The degree has been stable in the past two years; 3. Stable refraction for two years, good corrected vision and no other eye diseases; 4. There is no contraindication after examination., Some people think that laser surgery is effective only for people with high power. In fact, myopia, high myopia, hyperopia and astigmatism from 100 to 3000 degrees can be operated on. As long as the vision is not too poor, most myopia patients can get satisfactory results through laser surgery.,

recently, a news that “there will be no myopia in the world in 2017” exploded in the circle of friends. According to the article, a Canadian company has successfully developed a bionic lens, which can not only correct poor vision, but also better than 1.0 vision. This technology is being recognized by the national government and will be available as soon as 2017.

in recent years, news about myopia surgery has emerged one after another. Many people choose to have surgery in order to take off their glasses, because it only takes more than ten minutes to help myopic people have bright eyes again. Can myopia be cured? Authoritative ophthalmologists clarify common questions about myopia surgery for you.

myopia is a common eye disease, which has a great impact on vision. According to the survey of the Ministry of education and the former Ministry of health, the myopia rate of primary school students in China exceeds 25%, nearly 70% of junior middle school students and 85% of senior high school students. The myopia rate increases at a rate of 8% every year, ranking first in the world.

Liang Ge, director of Ophthalmology of the General Hospital of the Second Artillery Corps of the Chinese people’s Liberation Army, said that now, The most common method to treat myopia is excimer laser correction surgery (hereinafter referred to as “laser surgery”), but many people know little about this surgery, and there are some misunderstandings.

Myopia is caused by long anterior posterior diameter of the eyeball, too convex cornea and inaccurate convergence of external light in the fundus. Laser surgery for myopia is to use the laser beam to change the curvature of the anterior surface of the cornea to correct ocular ametropia. Generally speaking, it is to “grind” a pair of appropriate glasses on the cornea, so that the external light can accurately converge and image in the fundus, so as to achieve the purpose of correcting myopia.

and

have four conditions for laser surgery. Not all people with myopia are suitable for excimer laser correction, which mainly depends on the state of the eyes. Generally speaking, four conditions can be met: 1 At least 18 years old; 2. The degree has been stable in the past two years; 3. Stable refraction for two years, good corrected vision and no other eye diseases; 4. There is no operation contraindication after examination.

some people think that laser surgery is effective only for people with high degrees. In fact, myopia, high myopia, hyperopia and astigmatism from 100 ~ 3000 degrees can be operated on. As long as the vision is not too poor, most myopia patients can get satisfactory results through laser surgery.

clarify eight questions about myopia surgery

data show that about 1.5 million myopia people in China receive myopia surgery every year. Does this mean that these people may also face the pain of complications many years later?

and

to this end, we learned from Chu Renyuan, Professor of Ophthalmology of the eye, ear, nose and Throat Hospital Affiliated to Fudan University, and Huang Yifei, director of the excimer laser myopia correction center of the General Hospital of the people’s Liberation Army, to answer all kinds of doubts about myopia surgery in detail.

1 how many methods are there for myopia surgery?

at present, there are mainly two kinds of myopia treatment surgery: one is excimer laser surgery; The other is posterior chamber refractive intraocular lens implantation, which is often called refractive lens surgery. Refractive crystal surgery is called “addition surgery” in the industry, and excimer laser surgery is called “subtraction surgery”.

and

refractive lens surgery refers to the operation of adding intraocular lens into the eye and placing the lens in the safe area in front of the lens of the human eye, so as to achieve the effect of correcting visual acuity. Excimer laser is to correct myopia by cutting the corneal stroma under the corneal flap to reduce the corneal curvature of the pupil. This is also the most commonly used method at present.

  2How high is the success rate of myopia surgery? The success of

and

myopia surgery depends not only on the recovery of visual acuity, but also on the visual quality, including whether the distance and daytime vision are comfortable, whether the eyes are balanced, and how the three-dimensional feeling is. Now myopia surgery can do personalized cutting according to the specific situation of the patient’s eyes. Therefore, the total satisfaction has reached 97% ~ 98%.

3 what are the reasons that affect the success of surgery? What worries professionals most about

and

is that excimer laser surgery can be done everywhere, but the supervision of equipment and surgical personnel is very weak. For example, the most basic optometry, there are no professional optometrists in many places, and the information obtained by the machine is not accurate. It is conceivable that there are surgical problems.

in addition, the blade is not updated as required. Shanghai ophthalmic quality control center tracks and monitors the equipment of such operations every year. For some irresponsible medical institutions, the municipal ophthalmic quality control center has also strengthened the inspection of surgical blades. For example, in 2010, it was found that 2 ~ 3 patients were used for a blade in individual hospitals, In 2011, all medical institutions in Shanghai were able to strictly implement the regulation that one knife can only operate on one patient. Do complications occur after

4 operation?

and

complications mainly refer to the adverse effects directly caused by the operation, which mainly include the following three situations: inflammation after the operation, haze after the operation, keratoconus after the operation, and even blindness. However, these situations account for only a small part at present.

and

5 will there be no myopia after surgery?

at this stage, all surgical treatment methods for myopia belong to “symptomatic” treatment, not “cause” treatment. For example, excimer laser surgery can only “correct vision”, but not “cure” myopia.

for high myopia, myopia may be repeated. And after surgery, if you don’t pay attention to eye habits and eye hygiene, your vision will also decline again.

if vision drops again, with current technology, you can do the second excimer laser surgery or wear contact lenses. In the United States, 10% of postoperative patients wear contact lenses.

6 what should we pay attention to before operation? Before the operation of

and

, we must prepare according to the requirements of the doctor, keep the eyes in the best state, don’t stay up late and relax, stop wearing contact lenses two weeks in advance, and require antibiotic eye drops three days before the operation.

because there are many bacteria and other microorganisms in the conjunctival sac of normal people, preoperative medication can greatly reduce the chance of infection. Some patients come to have surgery. We can only ask him to order antibiotic eye drops many times a day, but we don’t advocate this.

7 what should we pay attention to after operation?

and

are not all right after the operation. Specifically, the following things need to be done well:

and

eye protection: the first week after the operation is a critical period to avoid rubbing eyes and water in the eyes. It is best to dry clean your hair in a barber shop within a week.

and

point medicine: point medicine according to the doctor’s requirements. Improper postoperative medication will also affect the operation effect.

and

reexamination: make sure to follow the doctor’s advice, especially regularly reexamine the intraocular pressure to avoid the occurrence of hormonal glaucoma.

and

for eyes: wound healing needs a process, and there will be a recovery period after operation, so you should pay attention to rest within a week. It is best to avoid long-term and high-intensity eye use within a month.

driving: try to reduce driving at night within a month, and pay attention to driving during the day.

exercise: within one week after operation, avoid sweat flowing into your eyes during vigorous activities. Avoid sports that may cause impact on the head and eyes, especially for patients with high myopia. Due to their poor fundus state, they should pay more attention to protection. Swimming is prohibited within 40 days after operation.

make-up: it is best not to make-up within three days after operation to avoid touching the eyes. It is best not to draw eyeliner and apply mascara in two weeks.

8 postoperative need to face the computer for a long time, will it affect the postoperative effect?

and

most of the patients undergoing excimer surgery are over 18 years old, and the degree of myopia is relatively stable. Facing computers and TV after surgery, it generally will not affect the effect of surgery, but they should also have a proper rest and don’t be too tired.

eat more fruits, especially citrus fruits. You should also eat more green vegetables, grain, fish and eggs. In addition, drinking plenty of water can also help reduce dry eyes.
