There are two main surgical methods.
1, laser surgery, including full femtosecond laser surgery, femtosecond laser combined with excimer laser surgery, and full excimer laser surgery.
2. Intraocular lens implantation for phakic eyes.
Adaptive population of laser orthodontics.
1, age > 18 years old, myopia 150~ 1500 degrees, hyperopia 100~ 1000 degrees, astigmatism ≤600 degrees.
2. Some patients with thin cornea and high myopia are suitable for femtosecond laser surgery.
3, the eye fissure is small, the corneal diameter is small, and the cornea is flat, so it is impossible to use a mechanical metal knife as a flap.
4. The first choice of traditional under-correction and over-correction after Lasik.
5. It is especially suitable for patients who are afraid of cutting cornea with mechanical corneal lamellar knife.

Prediction of myopia surgery prospect.
Because femtosecond laser surgery is not omnipotent, technical limitations cannot cover all myopia patients. At the same time, the high price of femtosecond laser surgery has also discouraged some patients.
In this case, SBK surgery came into being. Through technical improvement and innovation, the effect of SBK surgery is improved to almost the same level as that of femtosecond laser surgery, which provides a new surgical method for patients who missed femtosecond laser surgery at a reasonable price.
From the surgical effect, SBK surgery effectively fills a technical gap between other types of LASIK surgery and femtosecond laser surgery. From the technical advantages of SBK, it is possible to completely replace other types of LASIK surgery in the near future and become an advanced myopia correction surgery alongside femtosecond laser surgery, which will be a trend of laser myopia surgery in the future.
