Technology

Create perfect flaps without tissue bridges

FEMTO VISUM

Nanojoules at megahertz

Low pulse energy

Low laser energy and small focus spot result in small cavitation bubbles and a thin cut.

Low roughness

Distance between laser spots is smaller than bubble size- no tissue bridges, smooth surface of the cut.

Reliability

No risk of flap perforation or complete separation.

Thin flaps

Very thin flaps of less than 90 um are delivered for sub-bowman FemtoLASIK.

Another lasers

Microjoules at kilohertz

Higher laser energy

Higher cavitation bubble volume, gas formation, tissue destruction, thick cut.

Tissue bridges

Low frequency and large distance between spots result in tissue bridges remained between the bubbles.

Surface roughness

Flap surface higher roughness results in longer recovery.

MULTI OVERLAY

Scanning lines are overlapped to assure the cutting efficiency.

EASY LIFT

Additional energy is applied near the flap edge to assure easy detachment.

SMOOTH LINES

Spot density is decreased at the area of the line overlapping to assure the uniform cut.
