High score! High myopia do LASIK myopia laser surgery to help see the cornea!

Theoretically, you can do this power, but you understand that the principle of laser surgery is to cut your cornea to change the refraction, and the deeper the myopia, the deeper the thickness of the cut, the greater the damage to the cornea, and the greater the probability of complications. So it is recommended:

1 If you think about it from a life and career perspective, do you have to have surgery?

2 If you are determined to do it, a degree like yours requires a very high level of surgical accuracy than low-grade myopia, and you must choose a super-large hospital above the provincial level to do it. Of course, if you can go to a world-class ophthalmology hospital like Beijing Tongren Hospital for examination and surgery, even if you wait for a few more nights**, I think it is worth spending thousands of yuan for surgery, because caring for your eyes is the same as caring for life!

Honestly, I recommend that you don't do it, your eyes are already fragile, and there is no need to let the cornea...

The most terrible thing about high myopia is not the inconvenience of wearing glasses, but the possible complications, I think you just need to maintain your current vision level, so that the corrected vision after wearing glasses can reach and close to normal, there is no need to be too demanding of perfection.

I wish you all the best in the new year!

It can be operated on, but the cornea is still relatively thick.

The astigmatism is also not large. I've done it, and I don't usually do it. My sister has been doing this for more than 10 years and has been doing well. And I see that she also plays with the computer a lot.

Since Lasek cuts an epithelial flap, which is thinner than Lasik's corneal flap, it saves corneal thickness for some patients with a higher degree and thinner cornea, so some patients who cannot have Lasik can consider Lasek surgery.

2. Intraoperative: LASIK: only the corneal stromal layer is cut, and then the corneal flap is repositioned, which preserves the corneal epithelium and the Descemet's layer, so it is most in line with the anatomy and physiology of the cornea.

The procedure is quick and painful. However, the production of the flap is the main complication, which may produce corneal flap irregularity, perforation, dissociation, displacement, loss, corneal epithelial implantation or endophysis, and even flap melting.

LASEK: The epithelial flap was removed and the corneal Descemet's layer was destroyed, resulting in a series of problems such as severe postoperative response and longer recovery and medication time. But as with Lasik, the procedure is also quick and painful.

3. Postoperative: LASIK: light healing response, fast recovery, less pain, usually the second day after surgery, the patient can see clearly, and the basic feeling of suffering; Rarely, corneal haze haze; The postoperative medication time is short, usually about a month.

lasek: postoperative response is heavy, recovery is slow, usually takes two weeks or even longer, Fang ** bitter feeling, visual acuity is close to the preoperative expected level; The epithelium heals abnormally, and corneal haze is more likely to appear; The postoperative medication time is long, usually about 3 to 6 months, and there is a possibility of increased intraocular pressure due to the long use of hormones.

In summary, LASIK has become the first choice for most people because it is relatively fast, simple, has little impact on work and life, and has good surgical performance; However, for some higher prescriptions, the cornea is relatively thin.

LASIK surgery is to cut the cornea with a keratomatome, do a corneal section of 130um to 160um, and irradiate the laser, LASEK surgery uses special drugs to remove the 50um epithelial layer, and then irradiate the laser, so the amount of residual cornea after laser irradiation will be more than LASIK, which is a very safe surgical method.

Excimer laser surgery is to use a special extremely precise miniature corneal lamellar cutting system (referred to as corneal knife) to make the corneal surface tissue into a pedicle round corneal flap, after flipping the corneal flap, under computer control, the excimer laser is used to accurately vaporize the part of the tissue to be removed from the corneal stromal layer under the valve, and then rinse under the flap and reset the corneal flap, so as to change the shape of the anterior surface of the cornea, adjust the refractive power of the cornea, and achieve the purpose of correcting myopia, farsightedness or astigmatism. As long as the indications for LASIK surgery are strictly grasped and the preoperative examination is passed, LASIK surgery is basically safe to do in this case. Because the excimer laser is ultraviolet light with a wavelength of only 193nm, the wavelength is short, which is very suitable for cutting; What happens to biological tissues is that the photochemical effect is not a thermal effect, so there is no thermal damage, let alone a corretic cornea.

During the procedure, when the patient's eye deflects beyond the normal range, the laser automatically stops firing to ensure safety**.

The hospital is a second-level ophthalmology specialty hospital integrating clinical medical services, training and scientific research. We are committed to radiating Hong Kong's high-quality medical services to the Mainland, building a world-class international ophthalmic medical group with the original intention of doctors treating diseases and saving people, and striving to become a successful model of cooperation between the Mainland and Hong Kong in the medical field. <>

1. Myopia laser surgery is safe and effective, and will not cause harm to other structures of the eye.

So far, the results of domestic and foreign ** have been satisfactory, and the vast majority of patients have removed their heavy myopia glasses once and for all. The unaided visual acuity after the first is generally at or close to the corrected visual acuity with the forerunner glasses. So far, about 4 million patients in Japan have successfully undergone this surgery.

The success rate of myopia surgery has reached.

Years of theory and practice have proved that if the degree of myopia is stable and the anterior and posterior diameter of the eye is no longer longer, then myopia will not reappear after it. This wonderful laser makes the flattened part of the front surface of the eyeball not re-convex again, so the **effect is very stable, it should be said that it is a one-time**, permanent effect.

The excimer laser is an ultraviolet beam invisible to the human eye, and the excimer laser with a wavelength of 193nm can accurately ablate the part of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues and organs, and because it is a cold laser, it does not produce a thermal effect on the tissues next to the irradiation. With this accurate ablation, laser cutting does not penetrate the cornea, making it safer. Therefore, there is no *** to the tissues in the eyeball, and it will not cause side damage and sequelae.

2. Surgical conditions.

Guangzhou Amarshi Ophthalmology Femtosecond Laser Center experts will answer for you:

Although the effect of myopia surgery is good, it is not suitable for anyone, and the main surgical conditions are as follows:

1. Over 18 years old.

3. The diopter has been stable in the past two years, and its development rate is not greater than every year; (50 degrees).

4. Corrected diopter range (myopia 100-1200 degrees; Hyperopia within 600 degrees; astigmatism does not exceed 600 degrees);

5. Those who wear contact lenses (soft lenses should be stopped for 1-2 weeks, hard lenses should be stopped for 2-3 weeks, note: the shape and thickness of the visual membrane and the recovery of corneal epithelium);

7. Corneal thickness greater than 450 m;

8. Patients with no active eye disease in eye examination.

LASIK (Excimer Laser in Situ Keratomileusis): The procedure involves two steps, the first step is to create a flap and the second step is to cut off the power. Femtosecond lasers are used to make corneal flaps, (ordinary LASIK surgery uses lamellar knives to make corneal flaps); The excimer laser is used to remove the prescription, and these two types of lasers are the two tools used by doctors in the two steps of surgery, which are the same thing.

Sequelae of myopia eye surgery: There are two main problems: (1) Dry eyes after surgery, which is obvious in most people in the morning and relieved in 3-6 months for most people.

2) Glare, night vision loss, may affect night driving, this situation generally occurs in the preoperative dark pupil is large, intraoperative poor cooperation and high myopia patients, most of them gradually improve and disappear 3-6 months after surgery, and some people will last longer. Now the femtosecond laser in femtosecond laser surgery is used to make a corneal flap. Femtosecond surgery can eliminate almost all serious complications caused by corneal flap making because of the absence of a mechanical blade.

Complications such as retinal detachment, macular hemorrhage, vitreous opacity, glaucoma, cataracts, and even blindness are complications of myopia, and surgery does not increase the chance of these complications, nor does surgery reduce the chance of occurring. The principle of surgery is equivalent to wearing a pair of myopic glasses on the cornea of the eye, without any changes to the inside of the eye and the fundus.

Don't listen to them blowing, it seems that something will be advanced as soon as the United States is added.
