The small side of the Sensor Strip should be placed on the lower eyelid, with the end of
the Sensor Strip placed under the center of the eye. The side with the connection tab
should be located near the temple.
Align the Sensor Strip such that there is no hair beneath it.
LKC Technologies recommends the use of NuPrep
®
(made by Weaver and company and
sold on the LKC store, https://store.lkc.com), to prepare the patient’s skin in the
electrode contact area. Use of NuPrep will achieve electrical impedance levels
comparable to corneal contact electrodes and improves adhesion on subjects with
adhesion issues. Alternately, soap and water, or an alcohol wipe may be used but will
result in increased impedance. Use alcohol-based products with caution, as the alcohol
fumes may cause irritation to the eye.
If adhesion is still a problem after using NuPrep a medical grade adhesive tape at the
ends of the Sensor Strip can be used.
