Sequelae of laser eye surgery, sequelae of laser surgery of the eye

The myopia of the eye is due to the problem of the cornea, the light is refracted through the eye and imaged before the retina, but cannot be imaged on the retina normally. So blurred vision occurs. Severe myopia can choose laser surgery**, also known as corneal refractive surgery, which refers to the artificial cutting of the stromal layer or surface layer of the cornea through excimer laser or femtosecond laser, so as to change the radius of curvature or corneal thickness of the cornea, thereby correcting refractive error.

This kind of surgery is an invasive operation, although the current myopia laser surgery has been very mature, but if the operation is not done properly, it may lead to overcorrection of vision, vision**, corneal flap off-center, as well as lifelong glare and glare after surgery, etc., in addition, in the early stage, there will be a foreign body sensation in the eye, photophobia, glare or diplopia, corneal opacity, etc. Corneal flap crinkling or displacement, poor epidermal healing, infection, etc., may also occur. The incidence of these complications is usually low, and many of them resolve on their own after a period of recovery from surgery.

If you are afraid of surgery, or if your expectations are too high, it is recommended not to have surgery**. At the same time, if you must do it, you must find a regular hospital to avoid injury. I hope the above is helpful to you.

At present, with the development of science and technology, the application of laser surgery for eye diseases is becoming more and more extensive. Laser ** is characterized by small trauma and few complications, and there are many laser surgery methods currently used in clinical practice, after all, laser surgery is also an invasive operation, and it is inevitable that there will be certain sequelae. For example, in the case of laser surgery** in the myopic eye, there may be astigmatism symptoms due to improper treatment of the cornea, or undercorrection or overcorrection of vision may occur.

Laser** may also cause symptoms of dry eye in the eyes, or problems such as refractive regression and optical aberration. If the surrounding blood vessels are damaged, bleeding may occur, and there is a risk of local infection after surgery.

Severe myopia can choose laser surgery**, also known as corneal refractive surgery, which refers to the artificial cutting of the stromal layer or surface layer of the cornea by means of excimer laser or femtosecond laser

At present, corneal refractive surgery and phakic intraocular lens implantation are mostly used in myopia eye surgery. Since not all patients are suitable for myopia surgery, a detailed set of relevant examinations are provided to evaluate the patient before surgery and confirm that it is safe to perform surgery. Generally, in the early postoperative period, most patients will have dry eyes and fatigue, so artificial tears can be used to protect the eyes.

At present, myopia eye surgery has been carried out in China for more than 20 years, especially laser myopia eye surgery, which has a very high accuracy, and the vast majority of patients have achieved good vision improvement after myopia eye surgery.

The United States is a major country in myopia eye surgery, and the technology is also original in the United States. I looked through the American Journal of Ophthalmology, and their survey statistics showed that patients were very satisfied with myopia eye surgery, so myopia eye surgery satisfaction was very high. However, you must do a detailed examination before the operation, and cooperate well with the doctor during the operation to avoid complications or sequelae as much as possible, such as poor vision after surgery and decreased visual quality after surgery.

This is not currently happening in patients blinded by myopic eye surgery.

There is no need to worry about the after-effects of surgery.

First, refractive surgery is a corneal surface surgery, which will not directly lead to lesions and sequelae of other eye tissues.

Second, a detailed preoperative examination will be done before the operation to ensure that the eye meets the surgical requirements, and the doctor will operate on the patient;

Third, as long as the doctor's instructions are strictly implemented throughout the operation, there will be no rumors on the Internet about myopia surgery causing cataracts, retinal detachment, blindness, eye inflammation and infection, etc.;

Fourth, if refractive surgery does lead to serious complications and sequelae, will the state allow the procedure to develop so quickly?

Clause. 5. The laser used in the surgery is to scan the cornea accurately without harming the internal tissues of the eyeball. Excimer lasers are cold lasers that precisely ablate the portion of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues.

The wavelength of the excimer laser is very short and only 193nm, so it cannot penetrate the eye at all, so there is no harm to the internal tissues of the eye***. There is also no reason for the recurrence of sequelae after a few years.

Generally speaking, if you are over 18 years old and have stable vision, your postoperative vision will not be **. Because from the perspective of surgical principle, laser myopia surgery is based on the myopia degree you need to correct, under the premise of ensuring sufficient safety, the cornea of the corresponding thickness will be cut off, and the cornea will not grow out after surgery, so the corrected degree will not be **.

Before surgery, it is necessary to conduct a comprehensive preoperative examination to determine whether the operation is suitable and what kind of surgery is suitable, so that some uncertain factors can be eliminated and the safety of the operation can be ensured. Friends who need it can go to the hospital for a check-up first, listen to the doctor's advice before making a decision. I have a friend who was examined in the southeast, and the doctor said that he had keratoconus and did not recommend surgery.

1. Laser surgery is used to cut the cornea of the eyeball, and the higher the degree, the more it is cut, and the corneal flexion rate and thickness are changed to achieve the goal, but because the cornea is thinned, it will weaken the resistance of the cornea to intraocular pressure, so it is necessary to avoid strenuous exercise or vibration on weekdays, otherwise the serious consequence is blindness.

2. After laser surgery, severe acute disease may occur, the eye will have more and more severe astigmatism, the eye refraction will be wrong, the cornea may become thinner, and finally it may rupture.

3. Although laser surgery can allow patients to remove myopic eyes, and the naked vision after surgery can generally exceed or reach the first corrected visual acuity with glasses, some myopic people will also have insufficient correction of residual myopia after surgery, or overcorrection into myopia, and glaucoma will be induced in some cases.

4. Laser surgery may cause a series of complications due to surgical accidents and other problems, such as poor epidermal healing, corneal opacity, corneal flap fold or displacement, impurities or epidermal invasion under the corneal flap, infection, etc.

: There are sequelae after laser surgery on the eye, especially for patients with high myopia or astigmatism, the incidence of such sequelae may be relatively high.

The most common sequelae: dry eyes, or glare at night, dry eye, glare, myopia regression, overcorrection or undercorrection, corneal opacity, decreased visual quality, decreased contrast sensitivity, severe iatrogenic keratoconus; It may cause photophobia and tearing, and a small number of patients may also have eye infections or complications of eye perforation, which can lead to macular and vision damage in the patient's eyes. It can also lead to severe keratitis or liver inflammation.

Therefore, patients should pay attention to eye care after eye laser surgery and avoid long-term eye use.

Nowadays, there are more and more people with myopia, and more and more people want to choose laser surgery to completely get rid of glasses, so the safety and sequelae of laser surgery have become the most concerned issues.

Laser correction of myopia can bring permanent changes to the superficial structure of the cornea, corneal nerves, and corneal optical areas. Therefore, for the post-amnesia of laser myopia, we should talk about these three aspects.

Changes in the superficial structure of the cornea.

In surgery with a corneal flap, such as LASIK, the tangential stress in the corneal flap area on the surface of the cornea will be changed, which means that the force against lateral rubbing of the eye will be weakened, and the force may cause the corneal flap to shift in certain cases. The speed of femtosecond lasers avoids this pitfall, such as PRK, LASEK, and the safer femtosecond surgery that is currently available. Therefore, for patients who may engage in more allopathic activities in the future, or have concerns about this, femtosecond laser surgery is recommended.

Damage to the corneal nerves.

Superficial cutting will cut off the rich sensory nerves on the surface of the cornea, and the regeneration time of the nerves is relatively long, often taking half a year to a year. During this time, the weakening of corneal sensation leads to a decrease in the reflex secretion of tears, resulting in postoperative dry eye symptoms. Different people have different degrees of symptoms, and generally the symptoms will gradually decrease.

The main dissatisfaction or complications after laser surgery are residual refractive power, poor near vision, dry eye, and low vision in low light.

In general, myopia correction surgery is not a must-have surgery and can be expensive, so it is important to weigh the benefits and risks before surgery, and to have a full estimate of the risks of surgery.

In addition, a detailed preoperative examination is very important, and only when the conditions for surgery are truly met can the risks of surgery be minimized.

This consequence will not have an age, it should be related to the individual's physique.

Sequelae: intraocular or extraocular inflammation, keratitis, corneal perforation, aqueous leakage (most dangerous).

I am a doctor, and I suggest that if you are not highly myopia, it is best not to have myopia surgery, because these are new technologies, and they will not be as proficient as penicillin, and as for future complications, no one can **, because these are to determine the effect of people who have had surgery. In other words, you are doing it now so that future generations will learn from your experience.

This surgery, to put it bluntly, is to thin the cornea with a laser, so as to achieve a clear image of the eye, and the danger of this cornea thinning may be different for everyone. So it is recommended that you do not do it.

Let's be honest with glasses.

Laser**Myopia can cause uncomfortable symptoms such as swollen eyes, tiredness, headaches, etc. **The best way for myopia is daily care, you can eat more eye-friendly foods in your diet, mainly milk and its products, shellfish, bone meal, beans and soy products, egg yolks and dark green vegetables, which are good for the eyes, and then drink with Zheng 9 flavor pupil tea to help restore vision.

The sequelae of eye laser surgery are caused by the lack of eye care before and after surgery, as long as the patient takes care of the eyes carefully, there will generally be no sequelae!

This operation has been very mature, it has been in China for 30 years, and on average, hundreds of thousands of myopia patients have successfully removed their glasses through surgery every year, as long as it is determined that it is suitable for surgery through strict preoperative examination, the operation itself is very safe, and there are no sequelae.

I don't know what kind of laser your eyes do, myopia laser, glaucoma laser, post-cataract obstacle laser or retinal laser, black shadow is generally vitreous opacity! You need to know your condition to know if there's a problem.

If you do not meet the conditions for laser myopia surgery, surgery at a small, unqualified medical institution will inevitably have serious consequences. Therefore, laser myopia surgery must be done with strict and detailed preoperative examination to rule out contraindications to myopia surgery. If you fully meet the conditions for surgery, going to a regular professional eye hospital for myopia surgery will not produce the so-called sequelae.

Hello, over the years, the technology has been continuously innovated and matured, and as long as the preoperative examination meets the surgical conditions, the operation can be performed.

Hello, I suggest that you should be active in Beijing Tong Ren Tang Hospital**as well, **the most authoritative, I wish you good health, welcome to ask questions again.

There are many ways to get myopia, and you have to choose the most suitable way for you according to your actual situation and the doctor's examination results. Now in the summer, Hefei Purui has a summer mirror removal love action, there are ophthalmology experts to sit for consultation, you can go to their official website to make an appointment and choose a suitable plan for yourself.

There will also be sequelae after myopia eye surgery, but the incidence of sequelae is very low. The most common sequelae of myopia eye surgery are corneal edema, keratitis or corneal subepithelial opacity, and of course, there may be regression of the prescription and secondary keratoconus. Of course, these sequelae rarely appear now, because before the operation, the doctor will often conduct a series of examinations to see the specific condition of the patient's eyes, to see if the match is not suitable for surgery, and whether it is within the safe range.

This surgery is often done only if the indications for surgery are met. Therefore, generally speaking, the doctor will check it well, which greatly improves the safety of the operation, improves the success rate of the operation, and greatly reduces the risk and sequelae of the operation. Therefore, if you want to have surgery, you must go to the hospital as soon as possible to improve the relevant examinations, not all people can have surgery for myopia.

Have you already had surgery?

Excimer laser is an invisible ultraviolet beam produced by the excitation of fluorine argon gas after mixing, which is a cold laser that can accurately ablate the part of the cornea that is expected to be removed without damaging the surrounding tissues and other tissues and organs. In addition, the excimer laser has a very short wavelength of 193 nm and cannot penetrate into the eye, so there is no bad condition for the internal tissues of the eye, and there is no reason for sequelae to appear after several years.

If you will experience symptoms such as tearing, photophobia, and foreign body sensation in your eyes on the day after surgery, you should wipe your tears on your face after the tears have flowed, and do not use tissues or towels to touch your eyes directly. At the same time, you should try to close your eyes and rest, and do not move your eyes and rub your eyes. Most of the friends' eye discomfort can be relieved within 1 day, a very few friends may feel mild eye pain or subconjunctival hemorrhage (white eyeball patchy hemorrhage) after surgery, this is a normal phenomenon after surgery, its severity and length of time vary from person to person, subconjunctival hemorrhage can be naturally absorbed and dissipated in 2-3 weeks, in the early postoperative stage, some friends may have certain difficulties in seeing far and near, and may have symptoms such as uneven vision in both eyes or double vision, which may be normal conditions that may occur during the recovery process. Symptoms vary from person to person, and the sooner or later they appear and how long they last, so don't worry.
