1 Making a flap
I recommend making a flap with a Femtosecond Laser, the main type of Femtosecond Laser: IntraLase Fs Femtosecond Laser from AMO VisuMax Femtosecond Laser from Zeiss, etc.
At the same time, you can also make a flap with an IntraLase Fs Femtosecond Laser from AMO, and then make a flap with an IntraLase Fs Femtosecond Laser from Zeiss.
AMO's IntraLase Fs femtosecond laser is an infrared femtosecond laser to make corneal flap compared to the laminar knife with high precision, the error is about 5 microns. It is not easy to produce corneal flap flap making problems.
2 The flap is completed is the surgical laser.
I recommend using a wavefront phase contrast excimer laser: the American VISX STARS4 laser is the first choice. Wavefront phase contrast instrument with Wave Scan Wavefront phase contrast instrument Because VISX (VIS) excimer laser can produce different shapes of the spot, the largest 6.5mm minimum 0.65mm; spot smoothness is good, there are the advantages of large and small spot and can be tracked by the eye. Therefore, it is the first choice.
3 Surgery doctor: must choose a clinically experienced doctor.
Finally, I wish you good luck with your surgery!
