What are the types of tonometers?
What are the types of tonometers?
Types of tonometry
- Goldmann and Perkins applanation tonometry. The Goldmann applanation tonometer measures the force necessary to flatten a corneal area of 3.06mm diameter.
- Non-Contact Tonometry. Air Puff Tonometer.
- Schiotz Tonometer.
- Pneumotonometer.
- Tono-Pen.
Which drug is used for Applanation tonometry?
Applanation tonometry Because the probe makes contact with the cornea, a topical anesthetic, such as proxymetacaine, is introduced on to the surface of the eye in the form of an eye drop.

What does a Pachymeter do?
Pachymetry – A Simple Test to Determine Corneal Thickness A pachymetry test is a simple, quick, painless test to measure the thickness of your cornea. With this measurement, your doctor can better understand your IOP reading, and develop a treatment plan that is right for your condition.
What is applanation tonometry and how does it work?
Applanation tonometry is based on the Imbert-Fick principle, which asserts that the pressure (P) inside a sphere equals the force (F) necessary to flatten its surface divided by the area (A) of flattening, P=F/A. 1 In practice, multiple methods use this concept of flattening the cornea to measure intraocular pressure.
What are the different types of fingerfingertip injuries?
Fingertip injuries can occur in accidents at home, work, or play. An injury can involve a sharp cut, a crushing injury, a tearing injury, or a combination of these injury types. An amputation can result from slamming your finger in a car door or catching your ring on a hook or nail.
What is the goal of treatment for a fingertip injury?
The goal of treatment is to have a pain-free fingertip that is covered by healthy skin and functions normally. Your doctor will try to preserve the length and appearance of your finger. Treatment for a fingertip injury or amputation depends on the angle of the cut and the extent of the injury.
How do doctors treat fingertip amputations in children?
Doctors treat fingertip amputations somewhat differently in children younger than 6 years of age. After thoroughly cleaning and preparing an amputated fingertip, the surgeon may reattach it to the finger. The fingertip may continue to grow relatively normally, even if bone was exposed.
