Laser treatment of myopia, which originated in Europe and the United States, entered China 20 years ago. After 20 years of development around the world, laser treatment of myopia has become more mature and has attracted attention. Millions of people around the world easily fulfill their dreams every year. Nevertheless, ordinary people's concerns have not been completely eliminated, and people expect the operation to be safer and more effective!

"Full laser" is a gospel for myopia patients in the recruitment. Compared with traditional LASIK and femtosecond laser surgery, "full laser" does not cut the cornea and does not make corneal flaps. After surgery, patients are not afraid to bump or bump, even It is no problem to perform the most brutal special training and air flight, so it is especially suitable for myopia patients who want to be soldiers.

In response to the requirements of the new recruiting medical examination standard, Applicants who have undergone excimer laser surgery to correct vision, the interval between the operation time and the application time should be more than half a year. Myopic patients who have undergone surgery do not see any myopic surgery.

One: 20 years of traditional myopia laser and 10 years of femtosecond laser, but there are still insufficient

In the past 20 years, the development of laser treatment of myopia is divided into two parts:

1. Instruments and equipment are constantly updated: The excimer lasers of the 1990s have the basic performance of correcting myopia. After 2000, with the advancement of science and technology, the laser instrument has continuously completed many high-tech intelligent features, "infrared radar pupil tracking technology", which avoids laser deviation caused by eye movements due to tension during laser surgery; "Iris fingerprint technology" can accurately detect the rotation of the eyeball, ensuring the accuracy of treatment of patients with myopia and astigmatism; "wavefront aberration technology", known as space vision, this technology can ensure that the corneal surface is very smooth after laser treatment.

2. Surgical technology update: From PRK after 1990 to LASIK after 1995 to femtosecond laser LASIK after 2005, the vision recovery after laser treatment is getting faster and faster after all, although femtosecond laser caters to There is no psychological need for a knife, but femtosecond LASIK, like traditional LASIK technology, requires incision of the cornea before correction of myopia. The two are just the difference between a laminectomy and a femtosecond laser incision. "The incision of the cornea may lead to a reduction in corneal compression and the potential for potential corneal detachment," limiting people's choice of myopic laser.

Two: "full laser"-painless, knife-free, no need to cut the corneal flap, more secure

The traditional myopia laser LASIK and femtosecond laser LASIK both need to cut the cornea. After the corneal flap is cut, there are general concerns about the hidden danger of corneal compression loss and corneal flap detachment, and some patients have not opened the corneal flap within a few years. Complete healing, so patients after traditional LASIK and femtosecond laser LASIK surgery are often told not to rub their eyes, engage in strenuous exercise, military training and ball sports for weeks to prevent accidents.

"Full laser" for myopia, also known as "full excimer laser", this technology fundamentally abandons the key defect of "cutting the corneal flap". The basic principle of "all laser" for treating myopia is to use special The laser is directly applied to the corneal surface, so the "full laser" technology combines the advantages of PRK, traditional LASIK, and femtosecond laser LASIK, and the process is extremely simple, without any discomfort during the operation, and LASIK and femtosecond laser LASIK are completely avoided. Possible human error effects during the incision of the corneal flap. In foreign countries, the powerful advantages of "all-laser" have already attracted people's attention, and they have begun to be used and popularized.

Three: "All-Laser"-the preferred treatment method for students who love sports, military training, and military schools

Because "full laser" does not require incision of the corneal flap, the operation is simpler and safer. Therefore, you can engage in strenuous exercise and various military training 3 days after surgery. You do not need to worry about the possibility of the corneal flap falling off due to accidental injury to the eyeball during surgery. Occurrence of posterior dry eyes is rare, and combined with infrared radar pupil tracking technology, iris fingerprint technology and wavefront aberration technology, the visual quality after treatment is higher. Postoperative ease of movement, long-distance flight, swimming in the sea, etc. are not restricted. After "laser" myopia treatment, it can not only engage in common arms, such as special forces, submarines, and aviation. It is believed that it will soon replace femtosecond laser and traditional LASIK as the mainstream technology of myopia laser.

Four: the difference and comparison of "full laser" and femtosecond laser, full femtosecond laser

When it comes to myopia surgery, the most commonly heard is "femtoseconds". Is femtosecond perfect? At present, there is more and more publicity of femtoseconds. This reason is very complicated. It is driven by the interests of individual hospitals and invaded by Western cultures. The introduction of femtoseconds in some hospitals is also guided by public opinion. The second is not much different from the traditional myopic laser LASIK. Both are to cut the cornea to correct myopia, but the surgical patient needs several times the price. So, is there any better surgical equipment besides femtoseconds? Analyzed from the principle of surgery and safety, there is no doubt that "all-laser" is a more advanced surgical method. Femtosecond is only a transitional stage of myopia surgery. It is the general trend to be replaced by "all-laser".

In order to let everyone understand the advantages and disadvantages of the three all-laser myopia surgery more intuitively, the following introduces the differences between the three types of all-laser myopia surgery.

1. Applicable scope of surgery. 3 is the widest and 1 is the smallest.

2. The incidence of intraoperative complications. 3 points are the least, 1 points are the most.

3. Patient comfort during the operation. 3 points are the best and 1 point is the worst.

4. Time for postoperative vision recovery. 3 is the fastest, 1 is the slowest.

5. Postoperative corneal biomechanical changes. 3 is divided into the smallest, 1 is divided into the largest.

6. The incidence of postoperative dry eye. 3 points are the least, 1 points are the most.

Changzhou Puri Eye Hospital:

In 2011, the Changzhou Municipal Party Committee and Municipal Government organized a number of general hospitals in the east, west, south, and north areas of the city in order to meet the growing medical needs of the people in the Changwu area and facilitate the people's medical treatment. At the same time, in 2012, the Wujin District government approved the project of Changzhou Berui Eye Hospital, which is located in Wujin District, Chengnan, Changzhou. Some ophthalmologists led by renowned eye specialists Chen Bing, Lu Shuyu, and Fang Guoxin introduced the hospital. Ophthalmic specialty equipment was set up. The eye hospital currently has cataract department, glaucoma ophthalmology department, pediatric ophthalmology department, corneal disease department, myopia laser specialty, fundus internal medicine, fundus surgery and other specialties. Possessing total excimer laser treatment apparatus imported from the United States, American wavefront aberration apparatus, Olympus HD surgical microscope, German BAUSCH & LOMBMILLENNIUM cataract phacoemulsification all-in-one machine, France Everbright fundus photocoagulator, Germany Zeiss fundus imaging contrast device, Zeiss New equipment such as retinal optical coherence tomography (OCT). At the same time, Beijing, Shanghai and other external experts regularly visit the hospital every week, so that Changwu people will no longer have to travel to Shanghai, Nanjing and other big cities to treat eye diseases.

The hospital pursues the strategy of leading technology and expert presence, and introduces advanced equipment from the world. It has specialized eye diseases such as myopia laser specialty, cataract specialty, diabetic ophthalmology specialty and optometry specialty to meet different patients. The needs of the "corneal transplant specialist" to be established will fill this gap in the field of ophthalmology in the city.

He has been employed as the surgical guidance expert by more than 20 hospitals in Zhejiang, Jiangsu, Inner Mongolia, Shanghai, and Shaanxi.

Full femtosecond laser myopia (full femtosecond laser micro-incision corneal stromal lens resection) combines all the advantages of excimer and femtosecond technologies to perform laser blasting in the complete cornea to make pre-designed micro lenses , And take out the small incision to complete the correction of refractive error, surgery is safer and more perfect.

Five unique advantages of full femtosecond lead laser surgery to new heights safely!

Advantage one: original technology, no flap, minimally invasive.

Advantage 2: unique 3D cutting, more accurate surgical prediction.

Advantage three: reduce infection and postoperative complications.

Advantage four: The larger treatment range has the advantages of accurate cutting and high predictability.

Advantage five: stable postoperative refractive error, no regression, to ensure the safety of myopia patients.

Of course, not everyone can perform full femtosecond surgery. To perform full femtosecond myopia laser surgery, the patient's myopia degree must be within 900 degrees, and the degree must be stable for two years. In addition, patients with eye diseases such as dry eye, exophthalmia, and eyelid insufficiency, glaucoma, monocular patients, etc. are not suitable for surgery, and patients with corneal thickness below 450 microns are not suitable for surgery!
