With the FEMTO models, tunnel incisions may be shaped and positioned with a very high degree of precision.

Tunnels for Intracorneal Rings

Enhance your treatment options.

The FEMTO models create smooth customized tunnel resections to make the ring and inlay insertion easy. Their integrated OCT enables for more precise positioning of tunnel resections in the required depth and is helpful in cases with previous scarring. 

Benefits at a glance

  • Pre-programmed trajectories for most ring models
  • Individual customization for new ring models
  • One or two individual tunnels possible of up to 360 degrees
  • Individual resection depths and tunnel entries for both tunnels
  • Reverse side-cut (tunnel entry) possible to avoid ring segment extrusion
The FEMTO models offers multiple applications that can be customized for your surgical needs and it grows as your practice and technology advances.

Femtosecond Laser-Assisted Intracorneal Ring Segment Implantation

Customization

  • The depth, the inner and outer diameters of the tunnel incisions, the axis, as well as the entry incision angles can be customized to best fit the patient's surgery plan and to avoid any migration of the ring segments
  • For convenience, the FEMTO models include a pre-loaded library of ring models with its laser settings
Customization of the intracorneal rings - the depth, the inner and outer diameters of the tunnel incisions, the axis, as well as the entry incision angles can be customized to best fit the patient's surgery plan and to avoid any migration of the ring segments.

Centration and Rotation

  • With the FEMTO models, the tunnel incisions can be precisely centered on the monitor for more predictability in the outcome

Visualization after docking

  • The incisions can be easily viewed and adjusted on the TopView image and/or OCT even after docking
