The most advanced myopia surgery treatment in the world is LASIK, which is a combination of advanced technologies such as femtosecond laser (4th generation Intralase femtosecond laser), wavefront aberration (Wave-scan) and iris positioning (VISXStarS4IR), etc. The function of wavefront aberration is to reduce glare and make night vision more perfect; the function of iris positioning is four-dimensional The advantage of the femtosecond laser is that the flap is made and the embedded corneal flap heals more firmly. Therefore, in the United States, femtosecond laser surgery has become the first choice for myopia treatment, and in China, more and more myopic people are choosing to undergo femtosecond laser myopia surgery to successfully remove their glasses and embrace a clear vision. Femtosecond laser combined surgery has the following 6 irreplaceable advantages: 1. Femtosecond laser energy is uniformly and precisely distributed at low temperatures, taking care of every corneal endothelial layer cell. Femtosecond laser with top technology can optimize the shape and position of each laser beam and the repetition rate of emission, which basically does not increase the corneal temperature during the cutting process and reduces the cutting treatment time, making the surgery safer and the post-operative recovery faster. Second, the most advanced wavefront aberration technology can revolutionize the post-operative night vision of patients. ”Femtosecond laser flap making combined with Nuctech’s VISX wavefront aberration-guided LASIK technology can correct the patient’s high and low order aberrations through wavefront aberration technology, which is a milestone in improving the patient’s night vision compared to the previous lasik surgery. Third, the precise pupil automatic positioning technology can be perfectly matched to the optical center of the pupil. Pupil center automatic positioning technology is a key technology that is missed by many ophthalmologists. The surgeon needs to find the center of the pupil before performing myopia surgery so that the center of the excimer laser cutting can coincide with the optical center of the pupil. Fourth, femtosecond laser flap making is the safest. Femtosecond laser can produce corneal flap with more uniform thickness and perfect refractive index, which can avoid complications such as broken flap, free flap, button flap and medical aberration that may occur during metal keratome flap making, allowing patients to obtain better visual quality after surgery. V. Three-dimensional tracking technology strictly locks the optometric center of the eye. During myopia surgery, the patient’s eyes may swing or tremble involuntarily, making the laser not cut accurately to the intended point. The three-dimensional automatic tracking technology, combined with the pupil center automatic positioning technology, ensures that each laser cutting can reach the predetermined point more accurately. Sixth, the iris precision recognition function opens a new chapter of personalized treatment. The iris image of the eye, like a fingerprint, is unique to each individual. The iris positioning technology automatically adjusts the angle of laser emission during surgery based on the patient’s iris image, ensuring that the state of the patient’s eye at the time of laser emission exactly matches the state of the patient at the time of preoperative examination.
