Excimer sequelae? Tell me! Can anyone talk about it

The sequelae of excimer laser surgery mainly refer to some adverse reactions or complications that occur after surgery in patients with refractive error of excimer laser**. The first mainly includes refractive regression, which refers to the decline of vision for a period of time after surgery, which is mainly related to excessive eye use after surgery. The displacement of the second corneal flap is mainly due to the fact that the epithelium has not covered the incision within 24 hours after surgery, and if there is a case of eye rubbing or improper force, the displacement of the corneal flap can occur, so it is recommended to wear a corneal protective eye patch within 48 hours after surgery.

Thirdly, flare or diplopia is usually more common in the early stages of surgery, especially at night when the pupils become dilated, and most patients will gradually disappear over time. The fourth epidermis does not heal well, which is more common in PRK, and artificial tears can be used to help improve symptoms. The sequelae of excimer laser surgery refer to some adverse reactions after excimer laser surgery for myopia and hyperopia, which are generally rare, but due to the individual patient's own constitution, eyeball and improper postoperative maintenance, related symptoms may occur, as long as the preoperative examination is done to rule out the contraindications of surgery, a little sequelae will subside within a certain period of time.

The general sequelae is the postoperative refractive regression, that is to say, the phenomenon of decreased vision after a period of time after surgery, and the problem of corneal flap can also occur, such as the position of the corneal flap after surgery, its folds or folds, these problems often occur within 24 hours after surgery, before the epithelium covers the incision, so the patient should wear a protective eye mask before sleeping, 24 hours after the operation, the patient should do the first follow-up examination, if there is blurred vision, red eyes, pain or discharge, Long-term symptoms include inadequate correction, light sensitivity, glare or double vision, poor epidermal healing, subvalvular impurities, infection or tear secretion.

1. Security issues:

Excimer laser**Myopia is currently one of the safest surgical procedures in the world. This technology was first successfully researched in the United States in the eighties. Japan.

Developed countries such as Europe have also carried out it extensively. In 1993, approved by the Ministry of Health of our country, clinical trials were first carried out in major hospitals such as Beijing and Shanghai, and then promoted to the whole country, so far more than 600 hospitals have carried out this operation, 40 million people have received **, many famous athletes and actors have chosen excimer surgery for their careers and beauty, and myopic astronauts in China and the United States are also allowed to undergo excimer surgery. If there is a safety hazard, the Ministry of Health will not allow it to exist and develop.

Second, the sequelae of the problem:

The excimer laser is a cold laser that is extremely precise and can engrave on hair. The surgery is performed to reshape the cornea within the scientifically set limits, and there is no thermal effect when the corneal tissue is cut, there is no damage to other tissues, and there are no lesions left on the eye, so there are no sequelae.

3. Question:

The human cornea is like a convex lens, changing its refraction, you can change the focus point, so that the focus falls on the retina, the myopia problem is solved, the reshaped cornea, will not return to the original state, the thin lens will not become thicker, therefore, the possibility of myopia again is very small, and the normal eye will not be myopic again.

Fourth, the effect of the problem:

The effect of excimer laser **myopia is possible**, as long as your corrected vision can be achieved, the patient and the doctor can work closely with the surgery can be done or better, and it will remain unchanged for a long time.

This surgery is not something that anyone can do, so you need to consult clearly.

There are five common misconceptions about excimer laser surgery.

Myth 1: Excimer laser can hurt your eyes.

Experts pointed out that the principle of excimer laser myopia is that ultraviolet light is irradiated on the cornea of the eyeball, photochemical action occurs, a small amount of corneal tissue is cut, and the refractive power of the cornea is changed, so as to achieve the purpose of myopia. The excimer laser does not penetrate the cornea, but only cuts the surface of the cornea in the target area, so it has no effect on other tissues inside the eyeball.

Myth 2: Myopia will be after surgery**.

The so-called "**" is called "refractive regression" in medicine, which refers to the phenomenon that patients have myopia for a period of time after surgery due to individual differences, different types of myopia, and good eye hygiene. This phenomenon is mostly seen in people with ultra-high myopia, and the vast majority of myopia patients will not change much in their degrees after adulthood, and the laser cuts a part of the stromal layer of the cornea, which will not regenerate, thus ensuring the stability of the postoperative effect of the vast majority of myopia patients.

Myth 3: Surgery can be done for myopic eyes.

Experts say that not all patients with myopia can undergo excimer laser surgery. Patients with infectious inflammation, keratoconus, glaucoma, cataracts, fundus lesions, etc., or systemic diseases such as diabetes and connective tissue diseases are not suitable for surgery.

Myth 4: Myopia surgery is a minor surgery.

According to experts, excimer laser myopia correction surgery is not an ordinary minor surgery, and there are certain risks. The health supervision department has a strict evaluation system for the admission qualifications of hospitals, and doctors must have a certificate to work on equipment before they can perform surgery. In addition, there are strict requirements for preoperative examination equipment, related staffing, surgical process management and various links.

Myth 5: The recovery time after surgery is very long.

Experts remind patients that, in general, vision can be restored within 1-2 days after surgery, and that the ability to participate in normal activities depends on the patient's specific situation, the work they do, and the type of activities to be performed.

Don't do it, this surgery is irreversible, don't listen to the doctor, he can't say that the operation is not good, if it fails or has sequelae, what should I do, the eye is a lifelong thing, it can be disabled, but the eye can not be recreated, be cautious, I just have sequelae.

You must go to a regular and authoritative hospital to do it, you must do it after multiple examinations to determine that you can do it, you have to be over 18 years old to do it, I did it in 04, and there are no sequelae so far.

There are risks associated with any surgery, and we can only avoid them. 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.

The excimer laser is a "cold laser" produced by fluorine argon gas in the excited state that is invisible to the naked eye. Excimer laser surgery is a high-tech means of myopia, and it is currently a very successful corneal refractive surgery. Excimer laser surgery involves cutting a portion of the surface of the patient's cornea, which is equivalent to grinding a concave lens onto the eye.

This surgery thins the cornea, and for some patients with very thin corneas, there may be some problems with the cornea. Some patients also experience dry eyes after surgery.

Excimer laser surgery is currently an effective method for myopic eyes! Its indications are mainly 1: after the age of 18.

2. The degree of myopia is relatively stable within a certain period of time [generally half a year], 3 degrees are between 100 and 1500 degrees, and 4. There is no local acute inflammation of the eye in the near future! Generally speaking, as long as the above conditions are met, there will be no sequelae! However, if it is not a stable period of myopia, then it is likely that there will be postoperative sequelae in the future.

You should go to a regular hospital for **!

Yes, there are risks associated with surgery, and the risks of myopia surgery are almost the same as any surgery! Regression of vision, glare, dry eyes! Here are the main few common symptoms! But as for whether it is serious enough to affect life, it is also a matter of probability!

Don't be in a hurry to face difficult things and take it easy! It's a pity not to go to Shanghai Preh Eye Hospital! Hurry up and take a look, don't waste your time!

Before the operation, the doctor will give you a comprehensive preoperative examination, and the doctor will conduct a comprehensive evaluation and strict investigation according to the results of the examination to ensure that each surgeon fully meets the surgical indications before the surgery can be arranged.

The sequelae of this is that after the surgery, the glasses must not be impacted, otherwise the corneal transplant can only be performed.

Hello, the laser is a cold laser that acts on the cornea of the human eye, so that part of the tissues in the corneal ** area is ablated, so the corneal ** area is thinned, and the cornea becomes a similar concave lens, which plays the role of diverging light, and can also correct myopia. The whole process takes about ten minutes, and it is also very fast. **There will be a comprehensive and strict examination to screen before itself, and there is no problem with eligible eye conditions, if it is not suitable, it is not recommended**.

Laser myopia surgery is very mature at home and abroad, and if there is no problem in the preoperative examination, there is basically no problem after the operation.

The main thing is to maintain good eye habits, pay attention not to fatigue your eyes, and pay attention to hygiene.

Sequelae include refractive retraction, displacement of the corneal flap, glare or diplopia, and poor epidermal healing. Refractive regression refers to the loss of visual acuity for a period of time after surgery, mainly caused by excessive use of the eye after surgery. Corneal displacement is mainly caused by the epithelium not covering the incision 24 hours after surgery, and if corneal displacement occurs due to eye rubbing or improper force, it is recommended to wear a corneal protective eye mask within 48 hours after surgery.

Glare or double vision is usually common in the early stages of surgery and most disappear over time. Poor epidermal healing can be helped to disappear with artificial tears.

Tell me about it, and I'll analyze it for you.

Hello! It is true that there are sequelae of excimer laser surgery, but this is mainly due to the patient's personal physical factors, surgical equipment and the level of doctors.

Therefore, it is recommended that you choose a hospital carefully, in addition, careful maintenance after surgery, hygienic and reasonable eye use, which can effectively avoid the sequelae of myopia surgery.

The safety of the operation can be guaranteed as long as it passes a strict examination before the operation; It has been more than 20 years since the surgery was first performed, and it is now very mature, with tens of millions of people having successfully undergone surgery. At present, there are no adverse sequelae, but this is also related to the choice of hospital doctors and the advancement of instruments and equipment. Therefore, if you are considering doing it, it is recommended to choose a regular hospital.

Introduction to the sequelae of myopia eye surgery: The safety of laser correction surgery is related to the doctor's operating experience and equipment. Surgery is not risk-free, and there are two main postoperative complications to avoid.

Sequelae of infectionIf there is a wound in any cornea surgery, there will be a chance of infection. After the cornea is healed, the wound is exposed to the air, which can cause inflammation and infection if you do not pay attention to hygiene.

The sequelae of corneal expansion caused by too thin cornea **Myopia is to flatten the cornea, but the cornea that is too flat will be squeezed by the pressure from inside the eye, making the cornea bulge forward, this pressure is not felt by people, but the consequence is not only not **myopia, but will aggravate myopia, and even produce irreversible astigmatism.

Are there any postoperative sequelae of myopia correction?

There are no sequelae, and the surgery is done on the ocular surface without hurting your glasses inside, so don't worry.

I don't know if what my friend upstairs said is true or false. I'm a medical student, so it's easier to understand medical things. I'm also 600 degrees, and I wanted to do it, but now I decided not to do it. It is recommended that you do not do it if you use a lot of eyes.

The principle of surgery is to thin the cornea on the surface of the eyeball, and the principle of myopia is to lengthen the eye axis (increase in the vitreous of the ocular contents), and the operation is equivalent to changing the refraction of the cornea, that is to say, to correct myopia without glasses, but without glasses, and there is no real myopia.

Posterior migration of corneal damage? The cornea has poor resistance to compression, (it is not known whether keratoconus will be caused by surgery.) Keratoconus is not blind, but it is very eyesight-affected) is susceptible to infection, dry eyes, halos, dazzling, mild distortion and discoloration of vision, and so on.

After getting old. Easy to glaucoma, easy to go blind? Not very clear, not that old yet.

Anyway, the research on this surgery is not thorough, and I'm afraid no one can give you the probability data.

Eyes are meant to last a lifetime. Wait and see. See if there is any non-invasive myopia surgery in the future. Maybe I invented it... Ha.
