How many types of myopia surgery are there? What are the myopia eye surgeries

At present, there are many ways to perform surgery for myopia, and now the commonly used surgery is laser, which includes full laser, half femtosecond laser or full femtosecond laser, and different methods can be selected according to different specific conditions, and the cost of different methods is also different, relatively cheap is full laser surgery, and the most expensive is full femtosecond laser surgery. When choosing to undergo laser surgery**, it is also necessary to pay attention to the indications of the surgery, because the surgery is mainly for the cornea, if the cornea is too thin to be suitable for surgery, the thickness of the cornea is generally required to reach at least 450 m.

At present, there are four commonly used methods for myopia surgery: ICL lens implantation, femtosecond laser surgery, femtosecond laser surgery, and excimer laser surgery.

1. Corneal refractive surgery.

2. Phakic intraocular lens implantation.

3. Implantation of intraocular lens after cataract surgery.

4. Surgery on the sclera.

At present, there are two main types of myopia surgery: one is corneal refractive surgery, which is what we usually call myopia laser surgery; **Four or five thousand to one or two hundred thousand, the other is lens refractive surgery, including lens posterior chamber intraocular lens implantation surgery (i.e., ICL implantation) and clear lens replacement surgery** is generally more than 30,000.

Only after the preoperative examination will you know which surgical options you can choose. Only what suits you is the best, not the more expensive the better.

1. Excimer laser keratomectomy (PRK).

Excimer laser surgery uses a 193nm wavelength ultraviolet laser to accurately cut the optical area of the cornea and reshape the curvature of the corneal surface. For **myopia, the range of correcting myopia is best below 600. The disadvantage is that the surgery destroys the Descemet's layer of the cornea, which is easy to cause corneal fog opacity, vision regression and steroid-induced intraocular hypertension, and a small number of patients have vision regression for a period of time after surgery.

2. Excimer laser corneal in-situ in-situ in-situ inlay (LASIK).

The principle of this surgery is the same as that of PRK, but on the basis of not destroying the cornea and the Descemet's layer, it combines high-precision cutting and in-situ grinding in the corneal stromal layer with an excimer laser, which greatly improves the performance, stability and safety of the operation. This surgery has a wide range of corrections and can correct any myopia below 3000 degrees (if the preoperative comprehensive examination and all indicators are met). **After that, there is almost no eye discomfort, no need to cover your eyes, and you can go to work, school and participate in physical examination the next day.

3. Excimer laser keratomileus inlay under the epithelial flap (LASEK).

This method is used for special cases with thin cornea and high myopia. **LASIK surgery is the first choice for myopia. There is a difference between true and false myopia.

According to medical principles and clinical experience, any instrument and other non-surgical methods can only help to prevent and prevent pseudomyopia, and only surgical methods can be used for true myopia. Although there are many surgical methods, the commonly used and preferred is the LASIK laser myopia method, which is accepted by 90% of patients who want to be myopic in the United States. Its characteristics are:

It is convenient, bitter and direct, and it only takes more than ten seconds, and you can go to work, school, and participate in physical examination the next day, and it is a lifelong effect.

4. Intraocular refractive surgery (ICL).

This procedure is suitable for the elderly and those with ultra-high myopia**, and the original refraction is changed by removing the clear or opaque lens and implanting different anterior or posterior chamber intraocular lenses. The advantages are that the refractive effect is stable, there is no regression, and the postoperative recovery is fast.

There are several types of myopia eye surgery:

Standard Excimer Laser Surgery, Personalized Femtosecond Laser, Femtosecond Laser Myopia Surgery, Personalized Excimer Laser Surgery,

There are five ways to perform ICL surgery.

Myopia surgery is mainly for adults over the age of 18, as long as the surgical requirements are met and the preoperative examination is normal, the surgery can be performed.

Minors under the age of 18 are still in the stage of vision development, and the adjustment of the eyes is strong, and myopia can be treated by taking drugs. It is recommended to take Leyan Vision Nutrients, take it with warm water, and insist on taking it for a period of time, myopia will gradually improve, and you can avoid considering surgery after adulthood.

Myopia intramanual surgery has been developed for 20 years, and the technology is very mature, but there are risks associated with surgery, so it is necessary to be cautious.

There are many kinds of myopia surgery, the more common is laser correction surgery, it can be used for age 18-55 years old, 100-3000 degrees of myopia can be used, for high myopia patients have been successfully carried out a variety of methods, have different indications and characteristics, as for your situation can be operated on or not need to go to a regular hospital for strict examination, and to rule out amblyopia, strabismus and other eye diseases, such as through the examination, the operation is safe.

There are two main types of myopic eye surgery**: corneal refractive surgery and internal eye surgery. Corneal refractive surgery includes radial incision of the cornea, excimer laser, femtosecond and femtosecond laser, etc.

Internal eye surgeries include phakic intraocular lens implantation and clear lens extraction combined with intraocular lens implantation. Different surgical methods are suitable for different groups of people, young people with low myopia can choose laser surgery, while those who are older and have high myopia can choose inner eye surgery if they cannot be corrected by corneal laser.

Nowadays, the mainstream myopia surgery is divided into two categories: laser surgery and ICL lens implantation, according to your myopia degree and corneal thickness and other eye data, the doctor will choose the right lens for you.

At present, there are three types of surgery to modify corneal refraction and achieve the purpose of correcting myopia, such as corneal radial incision, excimer laser cutting, excimer laser corneal in-situ abrasion, femtosecond laser surgery, etc. The second type of surgery is phakic eye intraocular lens implantation surgery and aphakic eye intraocular lens implantation surgery, especially ICL intraocular lens implantation surgery to correct myopia. The third category is scleral shortening and posterior scleral reinforcement.

Surgery to correct myopia is risky and needs to be done carefully.

One type of surgery for myopic eyes is laser surgery, including excimer laser, femtosecond laser, and the other is intraocular contact lens implantation. Physician's advice: The surgery of myopic eye generally refers to excimer laser**Myopia surgery, the so-called excimer laser, refers to the laser produced by stimulated dimer.

Precautionary measures: It is recommended to go to a regular hospital for an examination, and according to the results, carry out **, so as not to delay the condition.

The rapid growth of the prescription is related to factors such as high learning pressure, not paying attention to eye posture, and the power of the glasses is not suitable, which will also make the prescription grow faster. In this case, it is necessary to go to the ophthalmologist to have your vision checked, do an optometry examination, and match a moderate number of glasses. It is necessary to pay attention to eye hygiene and reduce the time spent using electronic products such as mobile phones.

Hello, there are many types of myopia eye surgery, such as excimer laser and intraocular refractive surgery. Excimer laser, also known as corneal refractive surgery, is mainly performed on the cornea, including PRK, LASIK surgery, femtosecond, femtosecond, and so on. For some patients who are not suitable for corneal laser surgery, intraocular refractive surgery can be performed**, which has a certain effect on high myopia or astigmatism.

Hello, there are many types of myopia eye surgery. It is mainly divided into lasers and crystals, and the lasers are mainly femtosecond lasers, full femtosecond and half femtosecond laser surgery. Crystals are mainly lens implantation.

In addition, there are also superficial surgery and other methods. It is mainly based on the different conditions of the patient to choose different surgical methods.

Myopia surgery is currently divided into two categories: one is corneal refractive surgery, including excimer laser, femtosecond and femtosecond laser. The other is internal eye surgery, which refers to intraocular lens implantation, which is commonly used in people with insufficient corneal thickness or high myopia.

However, before surgery, it is necessary to analyze the appropriate surgical method according to the individual's eye power, corneal thickness, ocular surface and fundus and other examinations.

Myopia eye surgery is divided into laser surgery and lens implantation, laser surgery is now more popular full femtosecond full laser half femtosecond, you need to decide what kind of surgical method you are suitable for according to the eye examination data, before the examination, according to the degree there is no one-to-one surgical method to choose, some patients with better eye conditions, may be suitable for several or more ways after the examination, then the doctor will inform you in detail of the characteristics of various surgical methods, and then you will choose the surgical method in combination with your actual situation (economy, eye needs), If you have a higher power and a thinner cornea that precludes laser surgery for myopia, it is recommended to consider ICL posterior chamber lens implantation**. Southeast, Ophthalmology.

There are generally three types of myopia surgery:

1.Femtosecond laser: Femtosecond laser can usually cut the corneal stroma during surgery, which can improve the thickness of the cornea and change the curvature of the cornea, which can improve vision.

2.Excimer laser: The excimer laser can usually use laser methods to change the shape of the rubber opening surface of the anterior corneal pin, which can correct refractive errors.

3.There is phakic intraocular lens implantation, which is an intraocular refractive surgery that does not change the refractive shape of the cornea. Look

There are many types of myopia surgery, but the best one is femtosecond. Femtosecond is lasered and is the only surgical procedure specified by NASA.

First of all, you know which myopia surgery to choose to do, not the doctor and you can decide.

What really affects the way surgery is done is your eye data. Eye data** to come? Preoperative testing is available.

Specific preoperative examinations include: visual acuity examination, slit lamp examination, ophthalmoscopy, dilated refraction, computerized refraction, subjective vision, comprehensive refraction group, intraocular pressure, corneal curvature, corneal topography, corneal thickness measurement, eye axis, visual field examination, tear secretion tester and so ......on

The report of ocular data after the preoperative examination is decidative.

Maybe you're a good candidate for two surgeries, maybe three.

In the end, the doctor will also make reasonable recommendations based on your personal eye condition and financial situation.

Therefore, friends who want to have myopia surgery must do a preoperative examination for myopia surgery first.

**One of the safer surgical methods for myopia is excimer laser surgery, which has a wide range of correction and light postoperative reaction, and the damage caused is relatively small. The other is femtosecond laser surgery, which has a wider range of applications and can effectively reduce the risk of surgery. In addition, the ReLEx laser procedure is also very safe.

Myopia is a very common eye disease in life, and with the increasing application rate of various electronic products, more and more people suffer from myopia. Mild myopia can be adjusted by wearing myopia glasses, etc., but if it is more severe myopia, surgery is usually required**. So which is the safest myopia surgery?

1. Excimer laser surgery.

1.There is a wide range of corrections.

One of the safer myopia surgeries is excimer laser surgery. This surgery has a wide range of applications, as long as the degree of myopia is within 1400 degrees, it can be corrected by this method, and high astigmatism and high hyperopia can also be corrected by this method.

2.Postoperative reactions are mild.

The postoperative response of excimer laser surgery is relatively mild, it can preserve the barrier tissue on the surface of the cornea, and there is no pain after surgery, and there is no need for hospitalization and eye wrapping. Most patients have only brief periods of photophobia, tearing, and a foreign body sensation in their eyes, although the symptoms are mild and can recover within a short period of time. The patient's vision recovery is also relatively fast, and salt can be used directly after the operation, and it only takes a few hours to restore normal vision.

2. Femtosecond laser surgery.

If the thickness of the cornea is too thin or the degree of myopia is more than 1400, femtosecond laser surgery can be used**. This surgical method can effectively reduce the risk, is very easy to operate, and can improve the accuracy and biomechanical stability of the corneal flap. The induction of the corneal flap is more tightly reduced and more accurate and smooth.

It is not affected by the curvature of the cornea, and the scope of correction is more extensive.

3. ReLEx laser surgery.

ReLEx laser surgery is suitable for people who have stable diopters, no other eye diseases, correct the normal range of diopters, and like all kinds of strenuous exercises or special sports. The characteristics of this surgical method are that the whole process is femtosecond, no knife and no flap, and the whole process is completed with femtosecond laser, no need to make corneal flaps, and no need to combine excimer lasers to carry out**. This way is more effective and safer.
