Primacare Diagnostic Penlight


The PrimaCare Diagnostic Penlight is a tool that can be used by practitioners and patients alike. This disposable penlight can be used to measure pupil size, as well aid in the insertion of contact lenses.


**May be used in conjunction with the DMV Luma-Serter Plus by placing the Luma-Serter Plus on the lighted end of the pen.**



Instructions for use with the “Luma-Serter Plus”

CAUTION: Before using for the first time, clean the Luma-Serter Plus with alcohol and allow it to air dry.

Put the Luma-Serter Plus on the lighted end of the penlight. Place the contact lens on the center of the angled cup. Follow the lens preparation instructions provided by your eye care practitioner.

Turn on the penlight and gently move the lens toward the open eye by using the illuminated center of the cup as a guide. Hold the eye lids open with the other hand and place the lens on the cornea.

Once the lens has adhered to the eye, withdraw the Luma-Serter Plus. The light filter prevents contact lens solutions from passing through to the penlight.
