6 INSTALLATION AND CONNECTION

Steps What to do
1 Select the head
2a M2: Insert the
blade into the
blade housing of
the head
2b M2SU: lubricate
the head.
3 Assemble the
head into the M2
motor
4 Inspect the head
after assembly

IMPORTANT WARNINGS

• M2: select the appropriate pre-calibrated head. The microkeratome head is
labeled on its front side and indicates depth of cut.
• M2SU: select the appropriate pre-calibrated head. The microkeratome
head is labeled on its front side and indicates depth of cut. Disposable
M2SU heads are supplied sterile and for single use only. Check that
package is undamaged, unopened and within the expiration date.
• Lubricate the M2 head with balanced salt solution or another appropriate
ophthalmic solution.
• Inspect the blade and particularly the cutting edge before and after
insertion. Blades with spots, nicks, debris or other imperfections which
could compromise performance should be discarded.
• Insert the blade into the blade housing of the head, being careful not to
touch the front edge of the blade.
• Press gently on the blade and slide it completely into the head. In case the
blade does not slide smoothly into the head, check for debris or deposits
in the blade housing or on the blade itself. If, after careful checking of the
blade housing, it does not slide, replace the blade with a new one.
• Guide the blade into the head avoiding contact of the cutting edge with
metal part of the head.
• The blade design allows for only one direction for insertion and prevents
incorrect assembly.
• Before mounting the M2 head onto the turbine motor, make sure that the
blade holder slot is centered within the head (centered within the female
collar).
• M2SU heads are supplied sterile with pre-inserted blade to avoid blade
manipulation.
• Inspect the blade and particularly the cutting edge before and after
insertion. Blades with spots, nicks, debris or other imperfections which
could compromise performance should be discarded.
• Place the protective case on a flat surface and lift the top of package with
caution.
• Fill the cavity of the plastic package with balanced salt solution or another
appropriate ophthalmic solution to fully wet the head.
• Before using the M2 electrical motor ensure that the motor is clean and in
proper working order.
• Two different M2 motors exist: with and without the locking lever.
• M2: the electrical motor locks onto the keratome head:
o holding the microkeratome head, align the flat areas of the head and the
motor
o turn the head 1/4 turn counter-clockwise onto the nose of the motor
(finger tight only).
o check that the head is securely locked and tightened to the motor
• M2SU:
o keep the head in the package while setting it onto the motor.
o as for the reusable M2 head, screw the nose of the electrical motor
approximately 1/4 turn counter-clockwise onto the head
o keep the blister aside
• Check that the M2-M2SU head is securely locked to the electrical motor.
• If the head is not completely screwed on, the electrical motor will not drive
the blade holder and the blade will not move. Poor or irregular resection
can result from incorrect assembly.
• The head must be perfectly clean inside and outside and free from debris,
particles, oxidation and deposits. There should be no scratches on the
plates. If any, replace the head.
• After assembly and using a microscope, carefully inspect the blade under
high magnification to ensure that it is not damaged. If so: discard it (M2
blade, M2SU head) in an appropriate container and replace it.
