Tonometers are highly effective devices used for treating eye related disease

Tonometers |
Tonometers measure intraocular
pressure in the eye. Accurate measurement of this pressure is important for
diagnosing and managing glaucoma. They are available in many forms, from
well-established instruments to newer, less invasive devices. Each one has its
benefits and disadvantages and is used for different purposes and patient
populations.
They come in a variety of styles
and prices. Some are able to measure intraocular pressure without touching the
eye. A new version of the Perkins Mark 2 Tonometer has an ergonomic design and
a tonogrip prism holder.

Non-contact tonometry reduces the
risk of transmission of disease to the eye. Non-contact tonometry uses the
contour-matching principle and eliminates mechanical changes. Another new model
is called a Dynamic Contour Tonometer, or DCT. This device is similar to a
Goldmann applanation tonometer but is not a variable-force tonometer. They can
be used to diagnose or treat various eye conditions. However, it can be a good
option for a patient with a narrow range of IOP. There are different types of tonometers,
including the GAT, the Non-contact Tonometer, and the Goldmann Applanation
Tonometer. The latter uses a disposable metallic probe and colbalt blue filter.
These methods are less invasive and more convenient. Non-contact tonometry is
often used in pediatric care, and it is easy for doctors to perform it in
children.
Non-contact one are needs to be cleaned
and disinfected regularly. In general, non-contact tonometers
underestimate high IOP and overestimate low IOP.
Handheld one can be used to
measure IOP. They are portable and use a combination of applanation and
indentation to measure the IOP. This device has a small plunger and a footplate
that curves upward to contact the cornea. The weight of the plunger is
adjustable from 5 to fifteen grams. The amount of indentation the tonometer
creates is proportional to the IOP.
