For myopic dogs
Take off your glasses to see that everything is a natural mosaic
Myopia causes us to do whatever we do
It's not good, that's it
Myopia can also hurt our eyes
Increases the risk of many eye fundus diseases
Myopia for a long time, especially envious of good vision of the small partner, feel not myopic they are the chosen son! I believe that every myopic friend knows about myopia surgery and wants to do myopia surgery from the bottom of his heart!
However, every time I think about it, there are 1,000+ worries in my heart. Anyway, before doing it, let's take a look at myopia surgery!
1. What kind of person is suitable for surgery?
Friends who are willing to take off their glasses, or friends who want to restore their vision and have a clear vision because of factors such as examination, influence, do not want to wear invisible, work reasons, etc.
In addition, some conditions need to be met. Surgery may be considered for those who are generally at least 18 years old and whose number varies by no more than 50 degrees per year for two consecutive years. Otherwise, the surgery here has just been done, and your degree has risen again over there, then it is not the operation done in vain, and the glasses have to be put on again.
Usually requires myopia within 800 degrees and astigmatism within 600 degrees.
However, it is also necessary to combine the thickness of the cornea and the requirements for the degree of different surgical methods, so a detailed preoperative examination is needed first.
2. What preoperative tests do I need to do?
Preoperative examination is very important and serves two main purposes:
Exclude people who are not suitable for surgery
Choose the surgical option that's right for you
The specific preoperative examination items I will give you a brief list, according to the different circumstances of the individual will be different.
Optometry: Computer refraction will be done first, and then the optometrist will give you the main sensory refraction. The purpose is to obtain an accurate degree situation to ensure the effect of surgery;
Corneal thickness: Laser surgery is mainly to cut the cornea, therefore, there is a requirement for corneal thickness, and the thickness of the cornea and the difference in thickness will affect the choice of surgical method and whether it can be operated.
There are about 20 preoperative examinations. In general, if you have fundus lesions in your eyes, there are immune diseases such as diabetes and lupus erythematosus, and women are not suitable for surgery during pregnancy and lactation.
A detailed preoperative examination is performed, and the doctor can discuss which surgery to perform with you based on these indicators, as well as your specific needs, budget, etc.
3. Current mainstream myopia surgery
First, femtosecond laser myopia surgery:
Boai full laser femtosecond myopia surgery is a computer to control the depth and range of cutting, the whole process of using femtosecond laser and excimer laser to make corneal flaps and cut cornea, in the center of the cornea to make a smooth surface, change its corneal curvature, so that the light is directly focused on the retina, restore clear vision.
Femtosecond laser surgery advantages:
High stability of surgical operations;
Embedded reset, not easy to slip flap and shift;
The whole process does not use a "knife";
It is less affected by corneal curvature and has a wide range of corrections.
II. ICL lens implantation:
ICL, that is, implantable endocular contact lens, which is implanted into the eye by minimally invasive surgery, especially suitable for people with high myopia and ultra-high myopia, and high visual quality after correction.
Advantages of ICL lens implantation:
Can be used for myopia and astigmatism in a larger correction range (myopia 50-1800 degrees, astigmatism 50-600 degrees);
icl implantation is also reversible, and the crystals can be removed if necessary without causing changes in the structure of the eye.
Whether you can do surgery requires coming to the hospital for a detailed preoperative examination to know what kind of surgery is suitable!
