Thinking about the advanced technology brought back from the other world, Xiao Feng feels that it is really not difficult to get a dentistry!

Especially in terms of creating new dental diagnosis and treatment methods, there is no need to develop more advanced technology than Japan's, and even as long as he can get the same technology as Japan, it will be enough for his dentistry to be opened in the mainland.

After all, that's a position ahead of your opponent!

With the platform of their Sunshine Burn Scald Hospital to boost, the dentistry he wants to open starts more than twice as high as that of others!

Success is even more easy!

The longer the business is done, the more confident Xiao Feng is in his vision!

The dental industry, as Li Ran said, is indeed very promising, and the profits are still very high.

The most important thing is that the entry threshold for this field is relatively low, strictly speaking, it is a branch of orthopedics, and the general large general hospitals do not pay much attention to it.

So this is a very good opportunity for private capital to enter, although it seems that the market competition is fierce.

But if he has a dental practice, and his skills are really higher than others, he thinks that success is not a difficult task!

Another point is ophthalmology, which is indeed a very popular concept in recent years.

In major cities across the country, especially near schools, there are a large number of optical stores, with vision correction institutions of various names.

And these institutions are also very profitable!

Even the 315 party a few years ago has exposed some of these optical stores, or vision correction institutions' money-making methods.

But in the face of huge interests, these institutions are repeatedly prohibited, and so are the management departments...

Xiao Feng wanted to reverse this situation, because this time he brought back from the other world, there happened to be a drug that could effectively treat myopia.

"Li Ran, tell me what kind of means are generally used to treat myopia in the current regular ophthalmology?"

"At present, the most effective way to correct myopia on the market is surgery. At present, there are three mainstream surgical methods, namely TPRK also known as Trans-PRK, and the other two are ReLEx laser surgery Smile and laser Lasik method!"

Li Ran is really professional, and when he introduces it, Xiao Feng listens very carefully.

"The main principle of the TPRK method is to use a certain thickness of excimer laser to cut the corneal epithelium, cut off part of the Descemet's matrix, so that the corneal epithelium and the Descemet's layer matrix are completely removed, expose the stromal layer, and then use the excimer laser to cut the stromal layer according to the preoperative degree design to achieve the effect of correcting myopia. The cut corneal epithelium will grow completely in about 2-3 days. However, it will take three months of hormone drops after surgery to fully recover. The disadvantages are also very obvious, the recovery time is long, the recovery of vision is slow, and it is necessary to take medication for a long time. The advantage is that the difficulty is low, the price is cheap, and it can be done in 4000-10000 courtyards!"

Xiao Feng listened and nodded, it is estimated that there will not be too many people doing such an operation now, after all, the recovery time is too long, and it is too guilty.

"The other full femtosecond laser surgery, Smile, uses a femtosecond laser system instead of a mechanical lamellar knife to create a corneal flap. Under the precise control of the computer program, the cornea can be cut at any depth and shape, so the femtosecond laser can not only produce an ultra-thin corneal flap, but also pre-set the thickness and diameter of the corneal flap, the position of the corneal pedicle and the angle of the edge incision according to the requirements of the surgeon, so as to achieve personalized cutting according to different patient conditions. This surgery is actually a knifeless extension of the Lasik method, and the only difference from the Lasik method is that the surgery does not require the flap to be lifted. This method is also the most mainstream myopia correction surgery method at present......"

Li Ran is very familiar with these kinds of vision correction surgeries, and it is not difficult to introduce them.

He said it in simple terms, and Xiao Feng basically understood it.

In fact, the principle of these kinds of surgery, the TPRK method is to increase the angle of light scattering, so as to enhance the effect of on-retinal imaging, the disadvantage is that the postoperative recovery time is long and painful.

The advantages are that the difficulty is low, the safety factor is high, and the price is cheap!

The ReLEx laser surgery Smile, the laser Lasik method is actually to polish the lens on the eyeball thinner, and adjust the lens power according to the degree of myopia, which is like repolishing the convex lens in the eye to enhance the permeability.

The disadvantage is that the price is relatively expensive, and the advantage is that the recovery is fast and it does not hurt.

"At present, Smile is the mainstream operation in the vision correction industry, and the price of a single operation will range from 8,000 to 30,000 depending on the hospital and the patient's condition. ”

Xiao Feng listened to Li Ran's introduction and nodded constantly.

"The risk of sequelae after these surgeries... ”

"Uh... There are still some of this, such as the TPRK method, which will have the risk of eye deformation after this surgery. The other two also have such risks, and the most terrifying thing is that these three techniques cannot avoid recurrence. And once the myopia recurs, surgery can no longer be used to treat it, because it will increase the risk of retinal detachment!"

"And what is the approximate recurrence rate?"

Xiao Feng felt that he had grasped the key point, and then asked again.

Li Ran looked embarrassed, and after coughing twice, he said: "It depends on the patient's postoperative eye condition, if you take care of it, then the risk of recurrence is smaller." If you overuse your eyes, you will have a recurrence rate of 20 percent within three years, and after 10 years, the basic recurrence rate will be 50 percent, and after 20 years... We don't have detailed statistics for this data... ”

Xiao Feng nodded, although Li Ran said a lot of words, he basically understood that with these three surgical methods for correcting vision, the risk of recurrence after surgery is very high.

"You said that if we invented a liquid, similar to a liquid contact lens, and dropped it into the eye, it would ensure that the strength returned to normal, what do you say?"

Xiao Feng asked Li Ran with a smile.

When he came back from the Otherworld this time, when he was searching the medical cabin in Dragon City, he really found such a potion.

When he got it back, the robot Hubble simply told him that it was an eye drop.

And when he returned to the Copper Country and studied this potion, he found out that this is an ordinary potion? This is clearly a super bull potion?

It turns out that after the Falkens entered the interstellar age, they also often traveled between the universes.

However, people piloting starships often encounter various sudden bursts, or eruption rays.

For example, when a meteor hits a planet or a star, it will suddenly burst out with various super cosmic rays, and human beings who are caught off guard will inevitably be damaged when they see such rays.

In addition, some of the mechanics on the spacecraft often have to repair the machine in the dim cabin, although there is lighting, they still cannot ensure the normal use of the eyes, so the vision will also be damaged in a large area.

In order to protect people's eyesight, the people of Falken invented this super eye drop!

In fact, the principle of eye drops is very simple, that is, after this special eye drop is dropped into the eyelid, this eye drop will form a thin film in front of the human eyeball.

This film will have a similar effect to contact lenses, which can not only protect the eyeballs, but also automatically adjust according to the individual's myopia to become the most suitable contact lens for personal use.

One drop lasts for eight hours, and after eight hours you rest, you don't need to put it in, or you can choose to wear glasses.

Anyway, it's a pretty magical eye drop!

At that time, after Xiao Feng saw it, he immediately regarded this eye drop as a miracle medicine!

The key is that this potion can not only be used as a contact lens, but also has quite powerful medicinal uses, such as treating cataracts, glaucoma and other eye diseases.

Because the potion contains a bacterium, and the effect of this bacterium is so powerful that it is as powerful as a medical nanobot that can repair the human body!

It was this magical potion that made Xiao Feng move his mind to enter ophthalmology at this time!

After researching and understanding the magic and power of this potion, he hadn't thought about opening an eye hospital or anything.

But now that Li Ran has reminded him, he really thinks it's a good idea!

If you understand this eye drop, and then open an ophthalmology department in the Sunshine Burn Hospital, with the help of the platform of this Sunshine Burn Hospital, then it will be easy for this ophthalmology department to succeed!

And at this time, after he told Li Ran about the effect of this eye drop, Li Ran was already dumbfounded when he heard it!

"Mr. Xiao, I'm afraid you're not kidding me, right? If this potion really exists, then the entire world of ophthalmology will be subverted by you again!"

Li Ran's words are not joking, nor are they sycophants!

He was serious, if there really was such a miraculous potion, it would be a great blessing for all myopic eyes!

A drop of eye drops can cure myopia, without surgery, and without worrying about eye deformation and the risk of myopia recurrence, then this eye drop must be the first choice for all myopic eyes!

"Ha, what I'm talking about is just an idea! I invested in a scientific research team when I was abroad, and there was a project in this team to develop this eye drop. The last time I was in contact with their project leader, he told me that this eye drop was almost developed. And today you happened to come up with the idea of opening an ophthalmology department with me, so I just said it casually!"

Although Li Ran doesn't know much about Xiao Feng, he has a very good relationship with Guan Zhenhai, and he has vaguely heard some news about the big boss from Guan Zhenhai.

For example, the big boss has a special scientific research team abroad, and the research and development is all kinds of cutting-edge technology.

For example, the special scald cream currently used in their Sunshine Burn Scald Hospital was developed by the medical team!

If that team does develop these eye drops, oh my God!
