The 20-year-old Wang Ling now opens her eyes in the morning and can clearly see the park outside the window without wearing glasses The car's

LASIK for short) has become the most popular method at present.
The reporter learned that China introduced LASIK technology from the United States in 199. LASIK is "Laser" Abbreviation for -Assisted
in SituKeratomileusis", which means that the cornea is reshaped
without damaging the connected cell layers. As the axial length of the eye lengthens due to myopia, the lens of the eye becomes convex and the power of the eye increases. , so the light entering the eye
can only focus in front of the retina, making people unable to see objects clearly. LASIK surgery uses lasers to correct the patient's corneal surface
, flatten the center of the cornea, and reduce the patient's eye Diopter. In this way, when light enters the eye, it can be focused on the retina
and imaged, and people can see objects clearly.
LASIK surgery that is not covered by the basic medical insurance for urban residents is
a large expense for ordinary consumers. Taking Beijing as an example, the average cost of the surgery is about 8,000 yuan.
