Safety Information
The section lists:
• Specific safety precautions associated with the AccuPen
• General safety precautions
Safety Issues to Consider When Using the AccuPen
The AccuPen is noninvasive. The strain gauge sensor probe tip, covered with a
single-use latex disposable, touches the surface of the anesthetized cornea during
the scanning process.
Indications for Use
This instrument is used for measuring the intraocular pressure (IOP) of the eye.
It is to be used in a medical setting and only by physicians, optometrists, and
technicians who are experienced in IOP measurement techniques.
CAUTION: General indications for use of the AccuPen include on external, structurally
intact areas of the eye globe and orbit only.
Battery Disposal
Follow the procedure outlined below for proper disposal of lithium batteries.
1. Guidelines for the disposal of lithium batteries are continually under review.
Waste-management companies can provide assistance in the disposal of
these cells and batteries.
2. Disposal should be done in accordance with applicable regulations,
which vary from country to country. In most countries, disposal of used
batteries in the trash is forbidden. Disposal can be done through nonprofit
organizations mandated by local authorities or organized by professionals.
3. Cells and batteries should not be incinerated unless suitable procedures
are followed and appropriate precautions have been taken by qualified
handlers. Exposure of these cells to high temperatures or fire can cause the
cells to vent and/or rupture.
4. Used batteries should be shipped with the same regulations as those for
new lithium/thionyl chloride batteries.
5. Accutome recommends that cells and batteries for disposal should be
collected, transported, and disposed of in a manner that will prevent short-
circuit (the terminals taped).
6. Handling of used cells and batteries should be done according to the safety
instructions of fresh cells.
7. Recycling of the cells and batteries should be done in authorized facilities,
through a licensed waste carrier. A recycler in United States is listed below.

Accutome AccuPen User’s Guide
4www.accutome.com • [phone] US & CA • [phone] International • [phone] Europe
Disposal in Europe
The European Community (EC) has
issued two directives; 91/157/EEC
and 93/86/EEC. These directives are
implemented by each member country
in a different way. Thus, in each country,
the manufacturers, importers, and
users are responsible for the proper
disposal or recycling.
In accordance with these directives, the
AccuPen lithium cells do not contain
dangerous substances. The reaction
products are inorganic and do not
represent environmental hazards once
the decomposition or neutralization
process has terminated.
Disposal in the United States
Lithium batteries are neither specifically
listed nor exempted from the federal
Environmental Protection Agency
(EPA) hazardous waste regulations,
as conveyed by the Resources
Conservation and Recovery Act (RCRA).
The only metal of possible concern
in the cell is the lithium metal that is
not listed or characterized as a toxic
hazardous waste. Significant amount
of spent cells and batteries that are
untreated and not fully discharged
are considered as reactive hazardous
waste. Thus, hazardous waste of spent
cells and batteries can be disposed of
after they are first neutralized through
an approved secondary treatment prior
to disposal (as required by U.S. Land
Ban Restriction of the Hazardous and
Solid Waste Amendments of 1984).
Disposal of spent batteries should be
performed by authorized, professional
disposal company that is familiar
with the requirements of the federal,
state, and local authorities regarding
hazardous materials, transportation,
and waste disposal. In any case, it is
recommended to contact the local EPA
office.
