Which is better, wavefront aberration technology guided surgery or femtosecond laser surgery

Femtosecond is a thing, that is, the hospital in order to make a profit to launch to fool patients, femtosecond is also a kind of excimer laser surgery, not much different from traditional laser surgery, mainly the equipment for making the valve is different, but the parameters of the valve are the same as ultra-thin LASIK surgery, but the charge is indeed several times that of the latter. In fact, people who are attentive can see the problem: basically all public hospitals do not have this equipment, you can see if the hospital around you thinks is the most awesome has this equipment.

Why? Because the clinical experience with this technology is still too short only 2 years. As for some people saying that this equipment is very expensive, not all hospitals can afford it, will public hospitals run out of money?

Will there be no money? On the contrary, which private hospital owners can afford it? Whether you believe it or not, I believe it anyway, hehe!

Wavefront aberration technology is the first to be able to accurately measure myopia in different areas of the same eyeball, which is not possible with ordinary surgery. Then the wavefront aberration software in the computer depicts a "personalized" wavefront aberration graphic, the color and shape of the graph are determined according to the degree distribution of the eyeball, and after the graphic data is input into the excimer laser system, the intelligent variable spot is guided to truly "personalize" the myopia degree in each different area of the eyeball**, so that the eyeball can reconstruct the most perfect and smoothest visual sphere. However, it is necessary to choose the appropriate surgery in combination with the examination.

Boeing aberration femtosecond technology is the first to accurately measure myopia in different areas of the same eyeball, which is not possible with ordinary surgery. Wavefront aberration technology forms 1250 different oak analysis points on the cornea, so as to establish a 3D map of each person's special eye aberration, highly accurately record the aberration of each eye, and carry out personalized excimer laser surgery, so as to reduce the postoperative visual quality problems caused by ordinary excimer laser, so as to achieve better visual results. If you need to correct your vision, it is recommended to go to Guangzhou C-MER Ophthalmology.

Advantages of wavefront aberration guidance: Wavefront aberration-guided femtosecond surgery is based on the refractive data of the patient's eyeball"Tailor-made"The designed cutting scheme: the wavefront aberration technology is used to accurately measure the high-order aberration and low-order aberration of the eyeball, combined with computer technology to create a quantitative, intuitive and easy-to-understand three-dimensional family three-dimensional eye aberration map, and guide the femtosecond laser to personalize the ultra-small spot flying spot cutting, eliminate the human eye aberration, not only correct the visual impairment, but also improve the overall visual quality

The visual field is clearer, the visual sensitivity is improved, and the night vision is significantly improved, which improves the stability and stability of the operation.

Guangzhou C-MER Ophthalmology.

The medical team is strong, with an international advisory group composed of international ophthalmology experts from many countries, focusing on the diagnosis and treatment of difficult eye diseases such as vitreous and retina, glaucoma, macular beam and ear lesions, refractive correction, prevention and control of juvenile myopia, cataract, and has rich clinical diagnosis and treatment experience in other ophthalmic diseases. <>

Wavefront aberration femtosecond laser technology is a good **myopia surgery. Aberrations refer to the refraction of light by the cornea, lens, aqueous humor and vitreous humor in the eye, and if one or more of them are irregular, the image may be blurred.

Aberrations are divided into two types: low-order aberration is the so-called refractive errors such as myopia, farsightedness and regular astigmatism, while higher-order aberration is like irregular astigmatism. These aberrations can lead to a decrease in the clarity of vision, affecting the quality of vision.

The wavefront aberration technology is to summarize and correct the patient's high- and low-order aberrations, so as to effectively improve the postoperative visual quality and night vision, and greatly reduce the probability of postoperative glare.

Wavefront aberration femtosecond laser surgery is performed under the guidance of a wavefront aberration meter. After a series of preoperative examinations of femtosecond laser surgery, the wavefront aberration can be guided by wavefront aberration, which can reduce the factors that lead to the increase of postoperative aberration, such as intraoperative laser off-center cutting and unsmooth corneal cutting surface, so that the personalized cutting technology can reach a new height, and the real "eye measurement" surgical method can be reduced.

Nowadays, developed countries such as the United States and the United Kingdom have begun to carry out wavefront aberration-guided femtosecond laser surgery among their fighter pilots and marines to improve the night vision and fine imaging capabilities of soldiers.

Excimer laser surgery and iris positioning wavefront aberration myopia surgery are better ways to get rid of myopia, in which iris positioning wavefront aberration myopia surgery can provide higher quality skin slag vision for myopia patients. Then the following is a detailed answer by the optometry experts of Xiamen Eye Center. The iris positioning technology can automatically adjust the emission angle of the excimer laser according to the patient's iris image, so as to ensure that the state of the patient's eyes when the laser is emitted is consistent with the state of the patient's preoperative examination, and avoid the data failure caused by the axial rotation of the patient's eyeball.

This further improves the precision of personalized excimer laser surgery** for myopia, astigmatism and farsightedness, providing a more perfect and safe outcome for myopia patients. People who are suitable for myopia surgery guided by wavefront image filial piety: (1) People who pursue high visual quality, such as:

pilots, painters, marksmen, actors, pilots, etc.; (2) The diameter of the "pupil" at night is greater than 6mm, because the wavefront technology can overcome the night glare to the greatest extent and improve the night vision; (3) People with astigmatism greater than 75 degrees or more, because the wavefront technology can improve the accuracy of the astigmatism axis and the laser is more accurate, so as to improve the correction effect; (4) Within 1200 degrees of myopia, 600 degrees of astigmatism, and 600 degrees of hyperopia, and after strict preoperative examination; (5) For those whose best-corrected visual acuity is lower than the following, because wavefront technology can correct high-order aberrations that cannot be corrected by ordinary lenses, the quality of uncorrected visual acuity after surgery can generally exceed that of preoperative glasses; (6) Irregular astigmatism after other refractive surgeries can only be treated with wavefront technology; (7) Complications (such as glare, etc.) that occur after previous excimer laser surgery can be accurately corrected.

Personalized femtosecond lasers include wavefront aberration and iris localization technology. They are subject to a rigorous examination before surgery.

Femtosecond advantage: guess the potato.

1. Higher surgical safety. This is especially true for thin corneas and curved corneas.

For myopia surgery patients with large rate variation. 2. Better vision after surgery. It is for patients with myopia.

It provides a platform for maximum laser vision correction and optimal visual quality. 3. Corneal cutting is more accurate. Its accuracy exceeds that of traditional mechanical corneal lamellar knife several times, from the actual.

On the elimination of the possibility of serious complications and infections of the vision of the Wairang Zhao. 4. The process is more.

Safe. Designed for individual corneal conditions, a smoother corneal flap is created under computer control.
