In addition to being more comfortable, the
true benefit of the VisuMax’s curved contact surface is that it allows one to maintain visual fixation due to its minimally-induced pressure. This allows the VisuMax laser treatment to be properly-aligned on one’s
“true visual axis”, rather than one’s pupil as a landmark as with all other femtosecond lasers. This
alignment feature, combined with
ideal spatial-positional accuracy, explain why only the VisuMax is solely-capable of a single-step femtosecond laser refractive procedure, such as SMILE, which would be impossible without these capabilities.
