Chapter 37 Vision Correction
At present, there are nearly 45 billion people in the world who need vision correction, accounting for 63% of the total population, and 25 billion people have uncorrected vision!
Unfortunately, Zhao Ping'an is one of these 45 billion people. Although he also wears myopia glasses, it is not a real correction at all, and his eyesight has deteriorated over the years.

People with normal eyesight can never appreciate the feeling that the whole world is covered with a layer of tulle after taking off their glasses, nor can they understand how disgusting it is to have a pair of cold brackets on the bridge of the nose from time to time things.

Therefore, for the secondary purpose of saving himself and the vast majority of human beings, Zhao Pingan has a very bold idea - to design a product that can correct vision, and even achieve the goal of a complete cure!
At this stage, there are two most obvious vision correction methods in the world, one is laser in situ corneal ablation, and the other is orthokeratology.

Laser in situ corneal ablation, the English abbreviation is LASIK, currently LASIK surgery is mainly divided into two types due to the different lasers used, one is excimer laser, and the other is femtosecond laser.

Excimer laser, a kind of ultraviolet light invisible to the human eye produced by the mixture of fluorine and argon gases after being excited, has a wavelength of only 193nm and will not penetrate into the eye. It is a cold laser with no thermal effect and can be irradiated with 'The way to precisely gasify the human corneal tissue can achieve the purpose of 'cutting' and 'sculpting' the cornea without damaging surrounding tissues and other organs. Its unique properties are very suitable for corneal refractive surgery.

Femtosecond laser, a kind of infrared laser that operates in the form of pulses, has a wavelength of 1053nm and a very short duration, only a few femtoseconds (one femtosecond is 1000 trillionth of a second), which can realize different layers of the cornea. Cutting under arbitrary control.The femtosecond laser can be focused on a multi-space area smaller than the diameter of a hair, which is used for micro-fine processing. In the laser correction of refractive error surgery, a more uniform and perfect corneal flap required for surgery can be produced, so as to obtain more Good visual quality.

Generally speaking, femtosecond laser surgery is more advanced than quasi-fractional laser surgery, and its uses are more diverse, but it is not without risks. In addition to the most common undercorrection and overcorrection, there is still a chance of eye defects after surgery. Dryness, corneal flap opacity, vision regression and many other complications.

Orthokeratology lens, commonly known as "ok lens", is a kind of high oxygen permeable rigid contact lens with specially designed multi-arc inner surface. The eyesight above standard 600 can effectively curb the deepening of the degree. It is suitable for the age of 1-2. It only needs to be worn at night, without any dietary and eye taboos, and it can bring your life convenience to the greatest extent.

OK mirror is undoubtedly a very good vision correction device. Wearing it at night can achieve normal vision during the day without worrying about the danger of surgical complications, but its shortcomings are also obvious.First of all, the price is expensive. The price of a custom-made OK lens ranges from a few thousand yuan to tens of thousands of yuan, and it needs to be replaced every few years. In addition, the vision correction effect of the OK lens is reversible. If you give up using it After that, it will quickly bounce back to the state before using it.

So to sum up, so far, there is no vision correction method without drawbacks on the earth.

And this is undoubtedly a huge business opportunity!

It is conceivable that it is difficult to successfully solve this kind of problem that countless scientists have tried their best to overcome. I am afraid that ordinary people dare not even think about it, but Zhao Pingan has no idea of ​​retreating in spite of difficulties. Excited, because only such a product is what he urgently needs!

With the direction, the rest is research.

In fact, not only lottery draws are addictive, but sometimes scientific research is the same. Although it is very tiring, the joy after overcoming a world-wide problem is something ordinary people will never be able to experience.

Zhao Pingan found out very sadly that maybe he was born with the characteristics of an otaku, so he could only drift away on this road, and walked to the dark.

……

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

The company has relocated as a whole. Except for some people who continue to maintain the operation of the new village factory, others, including all scientific researchers, have all moved into high-end and atmospheric new buildings. Anping Science and Technology Research Institute has gradually gained popularity. Like before, she was so clear that she couldn't even see a ghost.

However, in the S area on the second floor of the research institute, it is still abnormally quiet. The door of the only laboratory in the entire area is closed, and no one dares to walk around here. Many people wonder what the purpose of this laboratory is. what?Especially those rookie researchers who are optimistic about the company's prospects and have just joined. 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. He is too young and wants to see the front of Lushan. .

Unfortunately, to their disappointment, the research institute has been officially put into use for more than a week, but the door of the laboratory, which is always brightly lit, is still closed, and there is no intention of opening it.

In addition to doubts in everyone's mind, there is more admiration. As the saying goes, no one's success is casual. People only see the glamorous side of the so-called geniuses, and they will never understand what they put behind them.

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

Zhao Ping's over-investment has also alarmed several high-level executives of Anping Technology. Cao Zheng and Zheng Xiling have visited him more than once and persuaded him not to work so hard, but Zhao Pingan 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 vision, starting with laser in situ corneal ablation, to see if it can be improved, so as to completely curb the occurrence of complications.

For this reason, 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 is better To avoid the shortcomings of the two, the laser rotary epidermotomy is used to "make an active epithelial flap" on the corneal epithelium, with a thickness of only more than 50 μm, which "saves" the corneal thickness to the greatest extent.

However, this approach still has flaws.

In the live experiments on animals, Zhao Ping'an found that since the rotation and deformation of the eyeball cannot be controlled when the eyeball is operated in the supine position, the accuracy of the operation is difficult to guarantee. Therefore, although the Epi-LASIK operation can reduce postoperative irritation, It can even reduce the incidence of corneal opacity, and can also inhibit myopia regression to a certain extent, but it is still not perfect.

So later, Zhao Pingan combined Epi-LASIK surgery with information technology in a whimsical way, creating a new type of laser surgery guided by the Trace positioning system. Before the surgery, Tracey/iTrace wavefront difference inspection, corneal topography Image inspection and iris photography, and then input the data into a special software system for online comparison.

In this way, no matter how the eyeball rotates or deforms, the laser can be positioned according to the inspection results, completely avoiding errors caused by eyeball deformation and rotation, and making laser refractive corneal surgery truly perfect.

It stands to reason that such a technology is enough to shock the world. It has successfully overcome the worldwide problem of perfect vision correction, but Zhao Pingan thinks it is still not good enough!

There are two reasons. The first is that it is too complicated. Such a brand-new vision correction device is not so easy to popularize, even if it is produced. There is a gap in time with Zhao Ping'an's plan; It is a matter of cost. If you want to perform such a vision correction surgery, the cost will be at least tens of thousands of RMB, which will undoubtedly make it lose its popularity.

Therefore, after much deliberation, Zhao Pingan made a move that might make people all over the world want to cut him alive!
He directly discarded this technology, everything returned to the starting point, and started all over again!

ps: I have been telling myself that this is a sci-fi work, and the necessary rigor and logic are still required, but writing it like this is really useless!Especially for handicapped people like me, how many hours I wrote these two chapters today (Chapter 2 is halfway through) I even forgot how many hours I have written, my heart is full!Recently, I have a mosquito leg, and I don’t expect to be rewarded. The recommendation ticket does not cost money. I hope that with the support of the brothers, remember to collect this book, otherwise the task is not up to standard, and I may run naked next week. Think about it Blush! (cover face)
