Does laser surgery have any effect on myopia? A little reassuring.

It is best to consult a doctor beforehand, and it is best to find the best hospital such as a hospital in the provincial capital, and it is best to use excimer and other surgeries.

Surgery is risky. You will only be eighteen years old next year, it is best to push back a few years, insist on wearing glasses in the past few years, pay attention to your eyes, and control the degree first, so as to reduce the probability of **. If nothing else, you won't be blind, otherwise no one can say.

Myopia laser surgery is very mature, as long as you become an adult, the myopia degree is stable and you can do the surgery, it is recommended that you choose a professional and authoritative eye hospital expert surgery, as long as the operation will have a certain risk, which can reduce the risk of surgery to a large extent.

Excimer Laser**The laser used in myopia is a cold laser that precisely ablates the portion of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues and organs. The technology of excimer surgery for myopia is basically mature, as long as the preoperative examination excludes surgical contraindications, the surgery is safe, and the effect of laser myopia is also stable.

In medicine, any surgery is risky, and there is no surgery that can avoid all risks, but regular hospitals, experienced doctors, and advanced surgical equipment can minimize this risk and ensure the safety of patients to the greatest extent.

Laser surgery is a type of elective surgery that has been performed in China for about 20 years, and it is mostly done on an outpatient basis without hospitalization, and some people say that it is a "cosmetic surgery" for the eyes. It is a symptomatic method for myopia, and myopia surgery is mostly concentrated in the people who are soldiers, recruiting police, taking civil service examinations, and going to school, and it is not recommended to do it if the occupation or life needs are not very high, or it is done with caution, unless it is difficult to tolerate wearing glasses or is eager to remove glasses. Most of the postoperative satisfaction can be, but the main problems are dry eye syndrome, poor night vision is the most common, refractive regression or ** is more common in surgical recipients with higher degrees, keratoconus or "blindness" has a low incidence rate, and a good preoperative examination can better avoid these problems.

In short, there are risks, and making a prudent choice according to personal work and life habits is a good choice for some people.

Ophthalmologist Shi Yongli Profile: Director of the Department of Ophthalmology, working in a tertiary hospital for more than 10 years, good at cataract, glaucoma, pterygium surgery and various ocular surface diseases, dry eye syndrome, keratitis and pigmentitis, fundus disease, various complex eye diseases, systemic diseases, ocular complications and difficult diseases.

The biggest difference between femtosecond laser** and ordinary excimer laser** is that there is no need to use the corneal lamellar knife to make the corneal flap, and the whole process is completed by the laser, so the problems unique to the corneal lamellar knife will not occur again in the femtosecond laser process, such as the knife, the corneal flap is free, the incomplete corneal flap, the flap is broken, the corneal flap is too small or too large, etc., so the safety is greatly improved compared with ordinary LASIK, but there may still be the following situations.

1. Do not squeeze the eyes and rotate the eyeballs during the femtosecond laser** process, otherwise there is a possibility of negative pressure, and if it happens, the corneal flap needs to be redone or the operation needs to be postponed.

2. If there is bleeding, secretion, filament, etc. under the corneal flap, it needs to be re-rinsed, if there is frequent blinking and eye turning after surgery, this possibility will be increased, and in severe cases, the corneal flap will be displaced, and it needs to be rinsed and reshaped again, which will generally not affect the surgical effect.

3. Postoperative intercalular inflammatory reaction, epithelial implantation, corneal flap ablation, etc., require drug or surgical treatment.

4. Due to the individual's sensitivity to laser and the degree of postoperative corneal biomechanical changes, there is a possibility of postoperative overcorrection, undercorrection and refractive regression. In general, refractive regression is related to the patient's preoperative refractive status, and the higher the power, the greater the likelihood of postoperative regression.

5. High myopia and astigmatism are pathological conditions, and myopia develops in stages or continuously, which is medically called progressive or pathological myopia. The disease is not completely determined before surgery, so there is a possibility that it will continue to develop after surgery, and glasses may be required if necessary.

6. Surgery does not improve or aggravate the complications caused by myopia patients (especially high myopia) (such as fundus hemorrhage, retinal detachment, degeneration, tear, concurrent cataract, etc.), therefore, it is still necessary to check the fundus regularly after surgery, in order to detect fundus lesions complicated by high myopia early.

7. During the postoperative recovery period, there may be dry eyes, reading difficulties, glare, night vision loss, night driving difficulties, etc., and the above symptoms may persist in individual patients.

8. After the operation, avoid sewage and foreign bodies entering the eyes, do not go to the environment where there are dust and unclean floating objects in the air, and apply the anti-inflammatory eye water in time and correctly, otherwise the cornea may be infected, and in case of serious infection, there is a possibility of serious damage to vision.

9. After the operation, some people will have red white eyes (subconjunctival hemorrhage), which is caused by the patient's squeezing of the eyes during the operation, which will be absorbed slowly and will not affect the vision.

Disadvantages of myopia surgery:

1. Postoperative undercorrection, regression, and vision loss should not be ignored.

2. After surgery, there may be halo and night vision impairment.

3. Dry eyes.

4. Complicated by severe keratitis.

5. Corneal flap dehiscence caused by accidental collision after surgery.

Myopia surgery has been developed for 20 years, and the technology is quite mature, but because it is a surgery, it is risky, so it is still necessary to be cautious.

And myopia surgery must be clear: myopia surgery must be over 18 years old, myopia degree between 100-1500 degrees, stable vision for more than two years, no other eye diseases, after a detailed preoperative examination, can be carried out myopia surgery.

Generally, children under the age of 18, because they are in the period of vision development and have strong eye adjustment, myopia can be restored by taking drugs to reduce the degree of myopia. It is recommended to take Leyan Vision Nutrients, twice a day, one pack each time, take it with warm water, and insist on taking it for a period of time, the myopia degree will gradually decrease, and it will avoid the trouble of surgery in adulthood!

Generally, there are complexes.

The preoperative examination did not cause any harm

Currently myopia is stimulated

The scope of application for photosurgery is that the age is over 18 years old, the myopia degree is stable for more than two years, the fluctuation of the annual degree does not exceed 50 degrees, the myopia is less than 1400 degrees, the astigmatism is less than 600 degrees, there is no active eye disease and systemic diseases that affect the surgical effect, if these conditions are met, you can consider myopia laser surgery. Although there are many ways of laser surgery for myopia, they all have their own scope of adaptation, and not all myopic people can do it, so it is recommended that you go to the hospital for an examination first, so that the doctor can choose the most suitable surgery for your eyes according to the specific condition of your eyes.

What should I pay attention to after surgery?

1. Pay attention to regular follow-up of medication.

2. High myopia still needs to be careful.

3. Still pay attention to eye hygiene.

4. Choose the right polarizer after surgery.

5. Pay attention to the balance of diet and nutrition after surgery.

Econda each national pupil kernel, acting directly on the eyes. It can improve ocular microcirculation, promote ocular blood circulation, can **myopia wish you happiness, and can also be used as an aid after surgery**.

Wishing you happiness!

Hello, laser myopia eye surgery is a rigorous one.

Factors affecting postoperative vision include preoperative safety checks, the selection of surgical equipment, the choice of surgeons, the choice of operating room environment, the choice of surgical methods and postoperative care, etc., myopia patients should consider these factors comprehensively, and choose a hospital with the best comprehensive strength to carry out the best visual effect!

Problem analysis: Hello, you can choose a regular eye hospital for glasses, which will provide medical optometry and other examinations to detect the existing diseases of your eyes in great detail, and the doctor will also provide a detailed correction plan.

My classmate did femtosecond ......The eyesight.,Look at the eye chart casually.。。 I'm going to do it too.

There are risks associated with any coming in for surgery.

We can only avoid risks. The risk-averse approach requires doctors with years of experience in excimer laser surgery and advanced ophthalmic equipment. The Ophthalmology Center of the 254th Hospital of the People's Liberation Army has more than 10 years of experience in myopia surgery, and has successfully done more than 40,000 cases of excimer laser surgery, none of which is unsatisfactory to the patient, and our hospital uses the most advanced American Nuctech surgical equipment in the field in the world, and has a computer to strictly control the whole process of laser surgery, and has an automatic eye tracking system, so that the laser has reached a high degree of safety, precision and perfection, in addition, the wavelength of this excimer laser is very short, For 193 nanometers is a kind of invisible ultraviolet beam of the human eye, which belongs to the cold laser, which can accurately ablate the part of the cornea that is expected to be removed without damaging the surrounding normal tissues and other tissues and organs, and it cannot penetrate into the eye, and there is no bad damage to the internal tissues of the eye, so the risk is relatively small.

Myopia laser surgery is a refractive optometric cutting of the stromal layer below the surface of the cornea with the incision of the surface layer of corneal tissue, so as to achieve the purpose of correcting myopia.

It should be understood that surgery is done to remove lesions in the body, and laser myopia eye surgery is different in that it is to remove part of the healthy corneal tissue.

It can be said that the simple pursuit of vision improvement and the destructive surgery of corneal tissue without disease is the biggest disadvantage of laser surgery, and it is also the greatest sorrow of the medical community. After this surgery, sequelae and complications such as vision loss are inevitable once the intraocular pressure increases.

Don't do it! No good!! There are only disadvantages!! Will regret it for the rest of your life.

Is there really a sequelae of laser ** myopia? Someone who has done it tells you the truth.

Surgery ** myopia, currently.

It has been used in clinical practice a lot, and the surgical technique is also very mature, so this is an optional operation, and the risk of surgery is also very small. The benefits of surgery are obvious, myopia can be completely corrected through surgery, improve vision, so as to achieve the purpose of removing glasses, and the trauma of surgery is very small, it will not bring great damage to the eyes, if the eyes are true myopia, you can consider using this method to **. There are currently two main types of surgery for myopia:

The first is corneal refractive surgery, which includes excimer laser surgery, femtosecond laser surgery. The second type is intraocular refractive surgery, which involves phakic intraocular lens implantation or lens exchange. Different surgical methods have different indications, so if you want to have surgery, you need to go to the hospital for examination and choose the most suitable plan according to the results of your own examination.

Myopia is caused by the length of the anterior and posterior diameter of the eye, or the increase in the curvature of the cornea, the distance between the retina and the lens becomes longer, and the light rays in front of the retina are focused, and scattered after reaching the retina, resulting in blurred images, which need to be corrected with concave lenses. There are several main reasons for its formation. Genetic and later irregularities in the use of the eye.
