Why didn t Ma Huateng have myopia surgery? 5

Non-surgical correction of myopia.

For most people, wearing glasses is a great option. However, be sure to go to a regular hospital or optician store when dispensing glasses. For school-age children and adolescents, optometry should be done after pupil dilation followed by glasses.

1) Eyeglasses have always been the main method of correcting myopic refractive error, and plastic lenses have been well popularized at present.

2) ContactLens (CL) CL is directly attached to the tear layer of the cornea to achieve the purpose of vision correction. Compared with orbital frame glasses, CL has a larger field of view, can maintain optical correction performance in all fixation directions, eliminates the triangular prism effect of glasses, eliminates oblique astigmatism, reduces binocular retinal aberration, maintains better binocular vision, is safe, convenient and beautiful to use, and there are some special lenses that can meet some special requirements.

According to the clinical report, compared with patients who wear glasses and orthokeratology lenses, the control effect of orthokeratology lenses is much greater than that of glasses (there are many clinical reports in this regard, and there is a certain gap between the results of different centers at home and abroad, the least reports of Beijing Medicine and the United States, the average annual growth rate is about 20 degrees, and the average annual growth of Sun Yat-sen Medical University in South Korea and Guangzhou is about 20 30 degrees, but there is still a big difference compared with children who wear glasses in the same period, and the annual growth of wearing glasses is generally 50 100 degrees). Our clinical experience is that most patients have significantly slowed down the progression of myopia, and many patients can completely control it.

Orthokeratology lenses use a special inverse geometry design of orthokeratology lenses, the inner surface of which is made up of multiple arcs (3-5 arcs). The uneven distribution of the lens and the tear layer, the resulting hydrodynamic effect changes the geometry of the cornea, and is worn in the front of the cornea while sleeping, gradually promoting the flattening of the optical area of the cornea and the shortening of the eye axis, thereby reducing the degree of myopia and astigmatism, and effectively correcting myopia and controlling its rapid development. In this way, it effectively prevents the development of myopia, and is known as "the technology that can control and correct myopia by sleeping".

The cornea is aspherical, and the vision is corrected with conventional methods such as frames, and the incident light is refocused on the retina at the cornea**, but is focused behind the retina in the mid-periphery. Leads to further growth of the eye axis. After orthokeratology, the cornea tends to be spherical, and the incident light falls on the retina at the cornea**, and the middle and periphery are refocused on or in front of the retina, which inhibits the further lengthening of the eye axis.

The age of myopia surgery correction is 18-45 years old, and he should not be able to do myopia surgery at his current age.

I'm older, and I don't have a plug-in

It is because there is no shortage of money that I do not have myopia surgery.
