Micrometer knives are designed for:
- refractive procedures such as radial and astigmatic keratotomy
- epikeratophakia
- corneal or scleral procedures requiring precise measurement of depth.

These knives can also be used in cataract and glaucoma procedures where the desired incision depth can be set using the micrometer.
- Incision depth from 0 to 1.5 mm by increments of 0.01 mm, turn micrometer thimble (2)
- Very precise ± 5/1000 mm
- Entirely in highest quality stainless steel
- Zero setting: under the microscope by means of the adjusting screw (1), at any time
- Fast retraction of the blade by bayonet push button system (3)
- Utilization of the blade at the required depth only by extension from the handle by pushing the button (3), the cutting depth remaining at the preset depth
- Available with different guards and foot plates.
