What are the differences between different myopia surgeries?

There are many surgical methods for myopia, which are generally divided into two categories according to different surgical methods; The first category is:Laser surgery**, also called corneal refractive surgery, including excimer laser surgery, femtosecond laser surgery;

The second category is:Intraocular refractive surgery, including phakic intraocular lens implantation and lens exchange, different surgical methods are suitable for different people and different degrees of myopia.

Therefore, if there is myopia in the eye, you first need to go to the hospital to improve the relevant examinations and clarify your condition before you can choose the most suitable method. It is generally believed that corneal refractive surgery is mainly used for myopia within 1500 degrees, and intraocular refractive surgery can be used for myopia within 2000 degrees.

Myopia eye surgery is mainly divided into several types: 1. Corneal surgery, that is, corneal laser surgery, through which a part of the cornea is cut off through the laser, and things can be seen clearly; 2. Lens surgery, there are two kinds of lens surgery, the first is to put a lens in the human eye, measure the prescription, and put the lens into the eye, which is called phakic intraocular lens implantation; The second type of lens replacement surgery is to remove a part of the tissue in the eye and put it into an intraocular lens; 3. Scleral surgery, which is mostly used is posterior scleral reinforcement surgery, which is mainly used to control the complications caused by myopia. The effect of high myopia on the function of the fundus and retina, so children or adults with particularly fast myopia development, or those with corresponding hidden dangers in the fundus, can take this type of surgery.

Myopia surgery is divided into these three categories, and it is necessary to go to the hospital to choose the appropriate surgery according to your own situation.

ReLEx laser surgery.

Originated from Germany, based on the femtosecond once again comprehensive upgrade, with all the advantages of excimer and femtosecond, and to achieve "no knife, no flap", more suitable for military schools, athletes, art students, civil servants and other groups with high sports requirements.

Femtosecond laser surgery.

Open the era of knifeless myopia surgery, which is safer and faster. Femtosecond technology is a NASA technology used by astronauts to boast a high level of safety. In the past 10 years, femtosecond technology has been an ideal choice for surgery for people with myopia.

ICL lens implantation surgery.

Ophthalmologists have been conducting decades of clinical research to develop customized surgical correction techniques for people with high myopia. ICL lens implantation is known as an aristocratic technique and is the choice of people with myopia above 600 degrees and extremely thin corneas.

The current types of myopia eye surgery are:

Standard excimer laser surgery.

Personalized excimer laser surgery.

Femtosecond laser myopia surgery.

Personalized femtosecond laser.

ICL lens implantation 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, and myopia will gradually recover.

Myopia 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.

What are the types of myopia eye surgery? How do I choose the right surgery for me?

The types of myopia eye surgery are: (1) excimer laser corneal resurfacing (2) excimer laser in situ keratomileusis (3) excimer laser subepithelial in situ keratomileusis (LASEK) (4) femtosecond laser myopia correction surgery. Generally, the effect of regular hospitals is relatively guaranteed.

Myopia eye surgery is to make a corneal flap only by femtosecond laser or lamellar knife, etc., and after opening the corneal flap, laser cutting is performed on the middle corneal stromal layer to change the refractive state of the cornea, and the cornea is reset to achieve the effect of accurate and safe correction of vision. At present, it is more popular to make corneal flaps by femtosecond lasers, which are safer and more reliable than the previous use of lamellar knives.

Hello, general myopia eye surgery is mainly divided into myopia laser surgery and lens implantation surgery. Lasers are mainly divided into full femtosecond surgery, half femtosecond, excimer laser, etc. Depending on the condition of the eye, different surgical methods are chosen.

There are three main categories:

Superficial surgery (RK, PRK, LASEK, TRANS-PRK), stromal surgery (full femtosecond, half femtosecond).

Lens surgery (lens implantation ICL TICL).

At present, the mainstream myopia surgery includes femtosecond, femtosecond and ICL lens implantation surgery, different surgeries correspond to different indications, if you want to do surgery, you can go to the local eye hospital for a comprehensive examination, according to the results of the examination, the doctor will recommend the right surgery for you.

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, the more commonly used surgical methods are femtosecond and ICL, femtosecond is to reduce the thickness of the cornea and correct vision through femtosecond laser, mainly for people with thick cornea and low myopia, ICL is lens implantation, implanting an intraocular lens in front of the lens to correct vision, mainly for people with thin cornea and high myopia.

Myopia surgery is divided into two categories: laser cutting and lens implantation, the difference between the two is that one is doing "subtraction" and the other is "additive". Laser cutting is to cut the stromal layer of the cornea of the ophthalmic state, that is, to do "subtraction", while lens implantation is to put the lens behind the sclera and in front of the lens, that is, to do "addition".

Specific analysis of these two types of surgery:

1. Laser surgery is suitable for those who are 18 to 60 years old and have a myopia degree between 100 and 1400 degrees of myopia. The outermost layer of the human eye is the cornea, which provides 2 3 refractive powers, equivalent to a fixed focal length lens of more than 4000 degrees. The cornea is made up of five layers, of which the stromal layer accounts for 80% of the corneal thickness and is non-renewable.

In corneal laser myopia surgery, the instrument will use a laser to cut off a part of the corneal stromal layer, change the curvature of the cornea, reduce the refractive ability, and refocus the light on the retina to correct vision. Laser surgery is further divided into three types: full femtosecond laser, half femtosecond laser and excimer laser.

1. Full femtosecond laser, it is suitable for myopia below 800 degrees, the trauma to the eyes is relatively small, and the safety is relatively high, it is the latest type of laser myopia surgery.

2. Half femtosecond laser It is suitable for myopia within 1200 degrees, and the postoperative recovery time is short, but it needs to make corneal flap sailing, and it must not be able to exercise vigorously after surgery, otherwise it may cause corneal flap displacement.

3. Excimer laser surgery can correct myopia below 1400 degrees, mainly because its safety is relatively low and the pain is relatively strong.

Second, lens implantation, this technology is suitable for the degree is too high, or the cornea is too thin, then the use of laser excision is not suitable, this method is equivalent to the doctor implanted in the eye built-in eye, can not destroy the corneal structure at the same time change the refraction of light, it is necessary, the implanted lens can also be taken out again, more test of the doctor's skills.

1. ReLEx laser surgery: This type of surgery is completely completed with femtosecond laser, which uses femtosecond laser to scan twice between the corneal layers to form a lens, and the lens is removed through a micro-incision, and the operation can be completed. Its biggest advantage is that there is no need to make a corneal flap, and there is no need to worry about the risk of corneal flap displacement caused by eye trauma.

2. Excimer laser surgery: The principle of this type of surgery is to cut the surface or stromal layer of the cornea through excimer laser, which can change the refractive state of the cornea, so as to achieve the purpose of correcting myopia.

3. Intraocular refractive surgery: The principle of this surgery is to implant an intraocular lens containing a prescription in the eye, so as to change the refractive state of the eye in this way, so as to achieve the purpose of correcting myopia.

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.

If you need vision correction, we recommend Guangzhou Yinghua Ophthalmology. [Click to test whether I am suitable for myopia surgery].

The four common types of myopia surgery are as follows:

1. Myopia surgery includes corneal refractive surgery. Corneal refractive surgery is a surgical method to change the morphology of the corneal surface to correct refractive errors, including myopia, farsightedness, and astigmatism.

2. Myopia surgery includes phakic intraocular lens implantation. For patients with high myopia, phacoemulsification of the lens is now suitable for implantation of an intraocular lens in the posterior chamber type, and there is no need to wear a mirror after surgery.

3. Myopia surgery and intraocular lens implantation after cataract surgery. Implantation of an intraocular lens during cataract surgery is necessary because the lens is present in itself and must be replaced with something else.

4. Myopia surgery on the sclera, you can operate on the anterior cornea, and the lens and sclera can be operated on, which is one of the first laser myopia surgeries. This method is suitable for patients with a diopter power of less than 600 degrees, a stable power for more than 2 years, and a patient older than 18 years of age.
