Traditional LASIK surgery can deal with 90%-95% of the lower order aberrations (such as myopia, hyperopia, astigmatism), but 5%-10% of the higher order aberrations (spherical aberration, comet aberration, cloverleaf aberration) are not corrected, and night glare, halos, double vision, irregular astigmatism, contrast sensitivity and night vision loss occur in some people. The proportion of new higher-order aberrations created during surgery is significantly reduced with the wavefront aberration technique, and the residual higher-order aberrations are significantly reduced after surgery, resulting in a more reasonable combination of all levels of aberrations in the eye after surgery. The majority of myopic patients who undergo “personalized” wavefront aberration-guided surgery have less significant differences in vision from traditional LASIK surgery within one to two months after surgery, and often show improvements in higher-order aberrations around six months after surgery. Iris positioning is iris recognition technology, the texture of the human iris is as unique as a fingerprint, each myopic person is equipped with a unique computerized identification treatment card, the machine identifies and then performs the surgery and records the data from the patient’s examination, fundamentally ensuring a high degree of safety in the surgery. Applicable objects: 1.Pursue quality vision, such as pilots, marksmen and painters; 2.Pupil diameter greater than 6mm at night, wavefront aberration can improve nighttime halos and glare phenomenon; 3.Myopia, farsighted people with astigmatism higher than 150 degrees; 4.After preoperative general optometry, wear lenses to correct visual acuity lower than 1.0
