Carl Zeiss, the world's leading manufacturer of optical instruments and equipment, has recently produced a globally unique full-femtosecond laser refractive surgery system, "VisuMax", which has led corneal refractive surgery into the era of full-femtosecond laser. The VisuMax is the first full-femtosecond laser system in the world.
Currently, the role of the majority of brands of femtosecond laser systems in keratoconus surgery is only to replace the corneal knife to make a corneal flap, after the flap is made, but also to use the excimer laser to ablate part of the thickness of the corneal stroma layer, reducing the corneal curvature (curvature), so as to achieve the purpose of correcting myopia. The "VisuMax" system from Carl Zeiss, however, uses a femtosecond laser to make the flap and reduce the corneal curvature (radius), making keratoconus laser surgery the first time that excimer lasers have been said goodbye.
In addition, the VisuMax system can be used not only for keratoconus surgery, but also for new clinical applications such as corneal transplantation.
