Principle of operation: The laser source in the VisuMax laser keratometer generates ultrashort-wave laser pulses (femtoseconds) in the near-infrared spectrum, which are transmitted to the laser output window through a series of various lenses in the beam scannerunit and laserarm. The laser source simultaneously emits a probe beam and a laser arm. The laser source emits both a detection beam and a treatment beam. The probe beam is used to adjust the focus of the laser on the z-axis relative to the plane of the negative pressure suction ring, and the treatment beam focuses the femtosecond laser pulse to a specific depth in the cornea, creating a photorefractive effect that separates the corneal tissue from the air bubbles.
Since the process of "Shen 5" to "Shen 16" series of manned spacecraft, there have been more than 400 Shenzhou heroes in the Shenzhen Boai Shuguang Ophthalmology Department of the diagnosis and treatment of correction, successful removal of lenses. At present, the hospital can carry out 16 mainstream myopia corrective surgeries such as German Zeiss full femtosecond smile3.0, American intralase150 semi-femtosecond, ICL crystal implantation, LASIK, etc., of which ICL and PRL crystal implantation have successfully corrected myopia for patients with 2,800-degree ultra-high myopia. The hospital has been awarded the title of "Youth Myopia Prevention and Control Alliance Hospital" and "Shenzhen Myopia High Risk Group Examination Designated Alliance Hospital".
