Anonymous users2024-02-11Femtosecond laser treatment for myopia can greatly reduce the risk of surgery. Femtosecond laser is an all-laser LASIK procedure that uses femtosecond laser to perform corneal flaps. Since it does not require a mechanical blade to make a flap, femtosecond laser LASIK surgery can eliminate almost all serious complications caused by corneal flap making.
It's just slightly higher, you can decide according to your actual situation.

Femtosecond laser-guided LASIK surgery is currently the latest technology in refractive surgery in the world. Femtosecond laser is a laser that operates in the form of pulses, with a very short duration, only a few femtoseconds, and a femtosecond is 10-15 seconds, which is one quadrillion per second of a second, which is thousands of times shorter than the shortest pulse obtained by electronic methods, and the shortest pulse that human beings can obtain under experimental conditions. This is the first feature of femtosecond lasers.
The second feature of femtosecond lasers is that they have a very high instantaneous power, which can reach one trillion watts, which is 100 times more than the total power generated in the world at present. A third feature of femtosecond lasers is that they can focus into areas of space smaller than the diameter of a human hair, making the electromagnetic field several times stronger than the force exerted by the nucleus on the surrounding electrons.
Femtosecond laser has the advantages of high safety, low probability of infection, strong accuracy, wide correction range, and perfect postoperative results, and this technology can bring better visual quality to patients with unique 18 safety rings, and provide a safety guarantee for surgery.

Anonymous users2024-02-08The femtosecond laser treatment of myopia often refers to the femtosecond laser as a flap, and the excimer laser is used to treat myopia after the flap is lifted, and then the flap is reset.

Anonymous users2024-02-05Compared with traditional laser myopia surgery, femtosecond laser has incomparable safety and visual advantages, specifically with the following advantages:
1. The risk of surgery is greatly reduced.
The femtosecond laser is a cold laser that does not damage the tissue when making the corneal flap, and the duration is very short, only a few femtoseconds, and the safety is greatly improved.
2. Make an embedded corneal flap for more accurate reduction.
The corneal flap made by femtosecond laser and the base of the eye are embedded in the form of an "underground manhole cover", which is easy to reduce and occlude tightly without misalignment, which also makes the recovery speed and better after the femtosecond laser surgery, and is more suitable for myopia patients with a lot of exercise.
3. Do not use corneal knife to avoid medical source ** staining.
The da Vinci femtosecond laser made it possible for the first time to leave the lamellar knife in corneal surgery, and cross-infection during the operation became a thing of the past.
4. The visual quality of da Vinci femtosecond laser is more perfect.
The femtosecond laser can accurately open the molecular chain of the eye tissue to produce a more uniform and perfect corneal flap, avoiding glare and ambiguity under visual conditions such as foggy days, rainy days and night driving, so that myopic people can obtain perfect visual quality, which is also the first choice for young people who drive at night and have high requirements for visual quality.
5. "All-laser" surgery, the accuracy is increased by 100 times.
The da Vinci femtosecond laser can control the accuracy of corneal flap production to less than 5 microns, which is more than 100 times more accurate than lamellar knife, which is a safer option for all myopia patients.
6. It is not affected by corneal curvature, and the correction scope is wider.

Safety,"The commonly used laser surgery at this stage is superficial surgery, which only makes a fuss on the cornea. The myopia lens is a concave lens, and the procedure is to grind the middle of the cornea, which is equivalent to making a lens on the cornea. Zhai Changbin said, "Comparing the eyeball to a basketball, surgery is equivalent to scraping on the surface, and it has no effect on the ball." >>>More
Depending on the type of surgery, femtosecond laser treatment for myopia ranges from 3k to 12k.
A femtosecond laser is a laser that operates in the form of pulses, with a very short duration, only a few femtoseconds, and one femtosecond is 10 to the minus 15th power, that is, 1,1000 trillion seconds, which is thousands of times shorter than the shortest pulse obtained by electronic methods, and almost the shortest pulse that human beings can obtain under experimental conditions at present. This is the first feature of femtosecond lasers. The second feature of femtosecond lasers is that they have a very high instantaneous power, which can reach one trillion watts, which is 100 times more than the total power generated in the world at present. >>>More
Judging from your description, considering that it may be related to long-term sleep deprivation, unreasonable eye use, and lack of movement caused by the change of the eye axis, the above two types of myopia laser surgery are currently the types of myopia laser surgery, they both change the refraction through the change of corneal thickness, but neither can completely restore myopia, only change the refraction. In general, femtosecond laser surgery uses femtosecond laser throughout the operation, while femtosecond laser surgery mainly uses laser when making corneal flaps and excimers when cutting corneas.
It is to cut a layer of your cornea with a razor blade, and then apply a laser on it to make the cornea thinner. And then cover that half... Myopia ......... achieved by changes in corneal curvature
