The first invention of myopia treatment surgery is which country

Pioneering period : Excimer laser treatment equipment was invented in 1983 and applied to clinical treatment of myopia in 1985, which made the safety and accuracy of myopia treatment substantially improved. PRK is mostly applied to treat patients with low and medium myopia below 700 degrees, and the disadvantage is that there will be pain in a few days after the operation. However, due to the disruption of the normal anatomical structure of the cornea, complications such as corneal clouding, glare and refractive regression can occur after surgery.

Popularization period: the first LASIK (IK, excimer in situ keratomileusis) surgery was successfully carried out in 1997 in China, LASIK surgery was developed on the basis of PRK, the surgery avoids the corneal epithelial overgrowth and corneal haze turbidity phenomenon after PRK surgery, and it is favored by myopia patients because of its wider scope of adaptation and more stable effect.

Enhancement: LASEK (EK for short, excimer laser subepithelial keratomileusis) is a brand new laser treatment myopia surgery for patients with thin corneas, high and ultra-high myopia that can not be corrected by LASIK, and after the surgery, it can solve the problem of aberration and glare for patients with ultra-high myopia, and the safety has been increased.LASEK is a new laser treatment myopia surgery to solve the problem of high and ultra-high myopia, and it is the first time to solve the problem of high and ultra-high myopia. LASEK is an effective refractive surgery method for patients with high myopia and insufficient corneal thickness, with minimal fluctuation in refraction and minimal refractive regression after surgery.
