Ophthalmic Tonometer

Ophthalmic tonometers are medical devices used to measure the intraocular pressure (IOP) of the eye. They are part of the supply class Ophthalmic Instruments, Equipment, and Supplies, which falls under the supply group Medical, Dental, and Veterinary Equipment and Supplies.

The intraocular pressure is the pressure inside the eye, and it is an important measurement in diagnosing and managing conditions such as glaucoma. Ophthalmic tonometers are used by ophthalmologists and optometrists to accurately measure the IOP.

There are several types of tonometers available, including:

1. Applanation tonometers: These tonometers use a small probe to gently touch the cornea and measure the force required to flatten a small area of the cornea. This measurement is then used to calculate the IOP.

2. Non-contact tonometers: Also known as air-puff tonometers, these devices use a puff of air to measure the IOP. The tonometer emits a quick burst of air onto the cornea, and the device measures the change in the cornea's shape to determine the IOP.

3. Rebound tonometers: These tonometers use a small probe that is gently applied to the cornea. When the probe touches the cornea, it rebounds, and the device measures the speed of the rebound to calculate the IOP.

Ophthalmic tonometers are essential tools in eye care practices as they help in the early detection and management of conditions like glaucoma. They are typically used in conjunction with other ophthalmic instruments and equipment to provide a comprehensive eye examination.

Please note that the specific features and functionalities of ophthalmic tonometers may vary depending on the manufacturer and model. It is always recommended to consult the user manual or seek guidance from a healthcare professional for proper usage and interpretation of tonometer readings.
