Zeiss VisuMax femtosecond laser can create the protective layer of the corneal tissue in a safe, reliable, quick and painless manner. This underpins the excellent results of IntraLASIK and IntraLASIK Wavefront methods. Everything is painless and without using any sharp instruments. During conventional LASIK-type surgery, the protective layer in the form of corneal flap is surgically created by means of mechanical microkeratome with a sharp vibrating blade. Although the surgery is extremely safe and reliable, the idea of a vibrating blade working on their eye is not acceptable for a number of patients.
