Femtosecond laser personalized flap making + excimer laser personalized cutting, creating perfect visual effects Dalian San Hospital Laser Myopia Treatment Center, using the latest generation of the United States Intralase femtosecond laser system, and excimer laser perfect combination to achieve the true meaning of all-laser myopia surgery. I. Femtosecond laser and excimer laser perfect combination to achieve a true sense of all-laser myopia surgery Femtosecond laser blade-free myopia surgery is currently the most cutting-edge technology for laser myopia correction. LASIK surgery is a two-step procedure: the first step is to create a corneal flap; the second step is a laser for refractive correction. Under computer guidance, the surgeon uses the femtosecond laser to precisely create the flap instead of the traditional mechanical knife, which is more than 100 times more accurate. Femtosecond laser flap creation has the following advantages: Advantage 1: Significantly improves surgical safety and avoids the risks associated with mechanical knives. Advantage 2: Increased surgical precision due to the full laser procedure. Advantage 3: Reduced postoperative aberrations and better visual quality. Advantage 4: Embedded corneal flap, more accurate and stable reset. Advantage 5: Non-contact corneal flap making, avoiding medical source infection. Advantage six: personalized corneal flap production, a wider range of treatment. Second, the characteristics of femtosecond laser femtosecond laser completely replace the traditional mechanical knife, with more than ten years of mature experience. Femtosecond laser is fully certified by FDA and SFDA of China. Femtosecond laser has become the mainstream surgery for myopia correction, which can be described as “customized” to create a more accurate and perfect personalized corneal flap, and its accuracy is more than 100 times that of traditional surgery. Femtosecond laser technology has been used by millions of myopic patients worldwide. NASA and the military have uniquely approved femtosecond laser technology for vision correction for astronauts and pilots.
