At present, nearly 4.5 billion people in the world need vision correction, accounting for 63% of the total population, of which 2.5 billion people have no vision correction!

And Zhao Ping'an is unfortunately one of the 4.5 billion people, although he also wears myopia glasses, but that is not a real correction at all, and his eyesight has deteriorated over the years.

People with normal vision will never be able to appreciate the feeling that the whole world is covered with a thin veil when they take off their glasses, nor can they appreciate how abhorrent it is to have a cold brace on the bridge of their nose all the time.

Therefore, for the secondary purpose of saving himself and the vast majority of human beings, Zhao Ping'an had a very bold idea - to design a product that can correct vision, and even achieve the goal of complete cure!

At present, there are no more than two most obvious vision correction methods in the world, one is laser in situ corneal excision, and the other is orthokeratology lenses.

Laser in situ corneal aluminescence, abbreviated as LASIK, is currently divided into two types of LASIK surgery due to the different lasers used, one is excimer laser and the other is femtosecond laser.

Excimer laser, a kind of ultraviolet light that is invisible to the human eye after being excited by the mixture of two gases of fluorine and argon, its wavelength is only 193nm, it will not penetrate into the eye, it is a cold laser, no thermal effect, and can accurately vaporize the corneal tissue of the human eye in the way of 'irradiation', so as to achieve the purpose of 'cutting' and 'carving' the cornea, without damaging the surrounding tissues and other organs, and its unique properties are very suitable for corneal refractive surgery.

The femtosecond laser, an infrared laser that operates in the form of pulses with a wavelength of 1053 nm and a very short duration of only a few femtoseconds (one femtosecond is one quadrillion second), can be used to arbitrarily control the cutting of different layers of the cornea. Femtosecond lasers can focus on multi-space areas smaller than the diameter of a hair, and are used for micro-fine processing to produce a more uniform and perfect corneal flap for the purpose of laser correction of refractive errors, so as to obtain better visual quality.

In general, femtosecond laser surgery is more advanced and versatile than fractional laser, but it is not without risks, and in addition to the most common undercorrection and overcorrection, there is still a chance of multiple complications such as eye dryness, corneal flap opacity, and vision regression after surgery.

Orthokeratology lens, commonly known as 'OK lens', is a kind of high-oxygen permeability rigid contact lens with a multi-arc area specially designed on the inner surface, which is characterized by the ability to enable myopic patients below 600 degrees to quickly reach the international standard of 1.0 or more within 1-2 weeks, effectively curb the deepening of the degree, suitable for 6-40 years old, only need to wear it at night, without any dietary and eye contraindications, and maximize your life convenience.

OK glasses are undoubtedly a very good vision correction equipment, worn at night, you can achieve normal vision levels during the day, and you don't have to worry about the danger of surgical complications, but its shortcomings are just as obvious. First of all, the price is expensive, and the price of a pair of customized OK lenses ranges from thousands of yuan to tens of thousands of yuan, and it will have to be replaced every few years; In addition, the vision correction effect of OK lenses is reversible, and if you abandon the use of the glasses, they will soon return to the state before use.

So to sum up, so far, there is no blind vision correction method on the earth.

And this is undoubtedly a huge business opportunity!

If you want to successfully solve this kind of problem that countless scientists can't overcome with all their efforts, the difficulty can be imagined, and ordinary people may not dare to think about it, but Zhao Ping'an has no idea of retreating, but feels very excited, because only such a product is what he urgently needs!

With direction, all that's left is research.

In fact, it's not just the lottery that is addictive, sometimes scientific research is the same, although it is very tiring, but the joy of overcoming the world's problems is also something that ordinary people can never experience.

Zhao Ping'an was very sad to find that maybe he was born with the characteristics of an otaku, so he could only drift away on this road and go to the dark.

……

Half a month later, Anping Science and Technology Industrial Park was successfully completed.

The company has carried out the overall relocation, in addition to leaving some people to continue to maintain the operation of the new rural plant, other people, including all scientific researchers, have all moved into the high-end atmosphere of the new building, Anping Science and Technology Research Institute has gradually gained popularity, no longer as clear and clear as before, not even a ghost can be seen.

However, in the S area on the second floor of the research institute, it is still quiet and abnormal, the door of the only laboratory in the entire area is closed, and no one dares to walk around here at will. Especially those rookie researchers who are optimistic about the company's prospects and have just joined, and at this time, the old employees will always tell them mysteriously: there is the exclusive laboratory of the founder of Anping Technology!

For this mysterious founder, many new employees have never even seen it, everyone is very curious, it is rumored that their big boss is just a college student who has just graduated, and he is a little too young, and he wants to see Lushan in front of him.

It's a pity that to their disappointment, the research institute has been officially put into use for more than a week, but the laboratory with always bright lights is still closed, without the slightest intention of opening.

In addition to doubts, there is more admiration in everyone's hearts, as the saying goes, no one's success is casual, people see only the glamorous side of those so-called geniuses, and never realize what they have paid behind them.

And this sentence is undoubtedly the most appropriate for their boss.

Zhao Ping'an's excessive investment also alarmed several senior executives of Anping Technology, Cao Zheng and Zheng Xiling have visited more than once, and have also persuaded him not to work so hard, but Zhao Ping'an didn't listen at all, because his research has reached a crucial stage!

For more than half a month, he has been exploring the possibility of using new technologies to correct his vision, starting with laser in-situ corneal extraction to see if it can be improved to completely curb the occurrence of complications.

To this end, he combined laser reduction keratomileusis (LASIK) and laser subepithelial in-situ keratomileusis (LASEK) in excimer laser surgery to create a new surgical method Epi-LASIK, which better avoids the shortcomings of the two, and uses the laser rotating epithelial knife to 'make an active epithelial flap' in the corneal epithelial layer, with a thickness of only more than 50 μm, which maximizes the 'saving' of corneal thickness.

However, there are drawbacks to this procedure.

In vivo experiments on animals, Zhao Ping'an found that because the rotation and deformation of the eyeball cannot be controlled during the recumbent surgery of the eyeball, the accuracy of the operation is difficult to guarantee, so although the Epi-LASIK procedure can reduce postoperative irritation, and even reduce the incidence of corneal opacity, it can also inhibit myopia regression to a certain extent, but it is still not perfect.

Therefore, Zhao Ping'an whimsically combined the Epi-LASIK procedure with information technology to create a new type of laser surgery guided by the Trace positioning system, in which Tracey/iTrace wavefront phase contrast examination, corneal topography examination and iris photography were performed before the operation, and then the data was entered into a special software system for online control.

In this way, no matter how the eye rotates or deforms, the laser can be positioned according to the examination results, which completely avoids the error caused by the deformation and rotation of the eyeball, and also makes the laser refractive corneal surgery truly perfect.

It stands to reason that such a technology is enough to shock the world, and it has successfully overcome the worldwide problem of perfect vision correction, but Zhao Ping'an feels that it is still not good enough!

There are two reasons, the first is that it is too complicated, not to mention the popularization of such a new vision correction equipment, even if it is produced, it is not so easy, and there is a gap between it and Zhao Ping'an's plan in terms of time; The second is the cost, if you want to carry out such a vision correction operation, the cost will be at least tens of thousands of yuan, which will undoubtedly make it lose its extensiveness.

Therefore, after careful consideration, Zhao Ping'an made a move that was spread out and was probably made people all over the world want to cut him alive!

He simply threw away the technology and returned to the starting point, starting over!
