High score for EK surgery for myopia

No play, EK only guarantees that it will not be found under the slit lamp examination, but because the laser cutting range is not very large, generally only a circular area of diameter, although it is larger than the usual pupil size, it will not affect the light convergence, but once the pupil is dilated, the pupil size is far greater than the surgical cutting range. When the pupils are dilated, the retina will not be able to concentrate light accurately (your visual perception will be severe glare, i.e., there are many thorny "light spines" near the light source, so that you can't see at all). Even if you don't say how you feel, the doctor doesn't need much experience to examine your eyes, take a small light source, look for your eyes, and observe the convergence of light on the retina of the fundus, because the surgical area is narrow, there will be two spots with different focal lengths on the retina, and they cannot converge at the same time.

This is very different from normal and can be checked out even by an inexperienced doctor.

As for the air pressure problem on the first floor, it is not a problem, the eyes are not gases, but liquids and solids, which are basically not affected by air pressure (the difference between air pressure and ground is many times higher than the intraocular pressure of people, and if it is really affected, normal people cannot bear it). And EK is not eliminated and cannot be replaced by LASIK. Lasik will have a residual corneal flap, which can be seen under a slit lamp.

And because of the presence of a corneal flap, it can lead to a range of problems. In addition, Epi-LASIK is not LASIK, but a type of EK, but a corneal epithelial flap (not LASIK's lamellar flap) made with a mechanical knife, and the postoperative healing method is similar to LASEK, and it takes a long time to recover. In fact, many ophthalmologists believe that corneal surface cutting is the trend, if you understand, you will know that although the recovery of surface surgery such as EK is slow, the recovery is complete, no wound is left, and it basically does not affect the sensitivity of vision, there are few dry eye symptoms, the new high-order aberration is lower than LASIK, there are no corneal flap complications (including corneal flap displacement and detachment by external force), and the cornea has good compression resistance; The disadvantages are slow recovery, greater pain, long postoperative medication, and high myopia may cause corneal opacity.

The disadvantages of LASIK residual corneal flap cannot be ignored, but it is precisely because the corneal flap will not really heal that it will have an immediate effect of rapid correction of vision, but I have to admit that after LASIK, the risk of severe eye dryness, corneal distension (even keratoconus), traumatic corneal puncture and so on is much greater than that of EK.

The status quo is that Chinese pilots do not recruit those who have undergone surgery, but ordinary soldiers can. No way, there are many Chinese, can't you find someone with good eyesight and the qualifications to be a pilot? Then again, not many people have the opportunity to fully realize their ideas.

If you are not suitable to be a pilot, don't force yourself, there are other paths to take, and you will find that the path is not necessarily worse than the one you originally wanted to take.

We usually say that doing some kind of myopia laser surgery is actually mainly differentiated by the way of making a valve, there are usually the following ways, PRK, LASEK, LASIK, ULTRA-THIN LASIK, EPI-LAISK, FEMTOSECOND, ETC., PRK is to use a corneal spatula to directly scrape off the corneal epithelial layer, the upper corneal matrix is lasered, postoperative pain, foreign body sensation and other adverse reactions will be more obvious, now this kind of surgery is rarely carried out, EK is to use an alcohol ring to remove the corneal epithelial layer, and then laser, Relatively speaking, it is lighter than the RRK reaction, LASIK is to use the corneal lamellar knife to make a pedicled corneal flap, and then play the laser, and then reset the corneal flap after the end, this surgical reaction is very light, and the eyes may be used normally on the second day after surgery, ultra-thin LASIK is the same as LASIK, but the flap is thinner, and the myopia degree can be higher, Epi-Laisk is made with a corneal epithelial lamellar knife (thinner), and the postoperative reaction is lighter than PRK, EK is lighter than LASIK. It is a scar surgery because the flap is very thin (50um) and will be ablated after a week, and femtosecond is a flap made with a femtosecond laser, and the valve is cut more evenly (very expensive).

LASIK, ultra-thin LASIK, epi-laisk, femtosecond are now popular surgical methods.

Generally, it will not be checked, but if you want to be a pilot, it is better not to do this surgery, because the air pressure at high altitude is different, and there may be any changes, and EK surgery has been gradually eliminated, and now the mainstream myopia surgery is LASIK and a series of surgeries improved by LASIK.

Dilatation of the fundus. Just look at it. Don't do it.

Go abroad, pay directly.

EK myopia surgery is called excimer laser subepithelial keratomileusis and is a type of excimer surgery. If you want to do EK myopia surgery, it is recommended to choose Guangzhou C-MER Ophthalmology.

The advantage of EK is that there is no corneal flap, which is suitable for those with a relatively small degree of myopia, generally according to the corneal thickness below 400 degrees, the advantage is that there is no corneal flap, and there will be no large astigmatism because of the corneal flap in the future, etc., suitable for patients who are soldiers, the disadvantage of EK surgery is that the corneal epithelium and stromal layer removed in the early stage need to heal gradually by themselves, so the medication time and medication care requirements are relatively high, so the EK surgery is suitable for small degrees. Patients who are able to be followed up until 1 to 3 months after surgery. EK surgery is an option. However, the long-term effect is relatively good, and there are no serious adverse consequences and reactions.

But choose a regular eye hospital.

Guangzhou C-MER Ophthalmology.

Based on providing high-end lean medical services for refractive correction and diversified diagnosis and treatment of eye health for children and adolescents, it has international equipment such as comprehensive refractor and imported femtosecond equipment, and has set up a special eye health science education base, and has also introduced a professional ophthalmology digital diagnosis and treatment system to build an ophthalmic transparent operating room and provide personalized visual diagnosis and treatment programs. <>

EK myopia surgery is a new refractive surgery method that is between PRK and LASIK, combining the advantages of both and avoiding some of the shortcomings. The principle of EK myopia surgery is to make a complete corneal epithelial flap with a special device, and then apply excimer laser surgery under the epithelial flap.

Advantages of EK surgery:

1. EK is also suitable for some special occupations, such as: people with high requirements for dark vision, engaged in sports, heavy physical work or poor working environment.

2. Compared with LASIK surgery, EK has a shallow cutting depth and no incision, which reduces the risk and improves the safety, especially suitable for patients with high myopia with thin corneal thickness.

3. The EK epithelial flap can effectively protect the incision wound and reduce the possibility of complications after surgery, which can cause symptoms of dry eye after LASIK surgery, but LASEK surgery will not cause dry eye, and the operation is safer.

Analysis: Myopia surgery EK refers to the first manual production of the corneal flap, and then some small trimming of the cornea, so as to change the refractive state of the eye, and then correct myopia. Excimer laser technology will be used during the operation, and routine disinfection and eye washing will be carried out before the operation, and the patient's excimer data will be input into the excimer laser computer.

Myopia surgery EK can correct myopia up to 1,000 taels, and the surgical effect is also very good. If myopia is present, this surgical option may be an option.

Normally, there is no pain during the operation of EK myopia, because the operation is performed on the cornea, you must follow the doctor's instructions during the operation, do not be nervous, the degree of pain after the operation also varies from person to person, the patient is best to be at least 18 years old, 25 to 30 years old This age is the best period for surgery, because the refraction during this period is a relatively stable state.

Myopia Correction Recommendations:

1. Pay attention to the time you spend with your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and acupuncture acupuncture points of Chinese medicine, combined with jujube Kuanhui medical sports, which is a scientific method to protect eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to eye nutrition.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

Regular check-ups are due to the fact that children's eye structure, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content of the examination is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.

EK myopia eye surgery is a minimally invasive surgery, the time is short, and there will be no obvious pain during the operation, so there is no need to be nervous, of course, everyone's tolerance level is different, and some people may feel very uncomfortable after surgery, but as long as you follow the doctor's instructions, you can try to avoid complications such as postoperative infection.

Hefei Aier Eye Hospital is a good choice, I was here some time ago to do femtosecond surgery and a comprehensive examination of the eye, the examination items are quite a lot, ** is also very reasonable, the doctors are very professional, the environment and facilities are first-class, the doctor explained very carefully.

Hello, EK surgery is characterized by safe and optimized surfacing surgery, laser scanning after making the corneal epithelial flap, maintaining the structural integrity of the cornea after surgery, and higher long-term safety, which is one of the preferred procedures for low to moderate myopia, especially for patients with relatively thin corneas, and vision recovery takes a week or more.

Note: It is normal to have a foreign body sensation, tearing, and mild pain 1-3 days after surgery. The postoperative medication time is long, and the patient needs to follow the doctor's instructions for regular follow-up.

EK is an excimer laser, and femtosecond is to first make a flap with a femtosecond laser and then use an excimer laser to adjust the corneal curvature. EK recovery is slow, femtosecond is fast.

The femtosecond laser uses a laser to achieve photodynamic blasting of corneal tissue, which does not damage the corneal tissue in less than 30 seconds during the process of making the corneal flap, and the safety is greatly improved. 1. Micron precision, higher accuracy: femtosecond laser can control the accuracy of corneal flap production within 10-15 microns, and the higher safety of femtosecond is self-evident.

LASIK, ultra-thin LASIK, epi-laisk, femtosecond are now popular surgical methods.
