# What is ocular response analyzer?

An ocular response analyzer is a device that measures eye pressure and corneal biomechanics in more detail.

## How the ocular response analyzer works

Similar to a puff test, it sends a rapid air pulse to the cornea. Sensors then record how the cornea bends in and out, giving information about its stiffness and true pressure.

- The test is quick and non-contact, using air rather than instruments
- It provides two pressure readings and corneal hysteresis values
- Results are especially helpful in glaucoma assessment
- You can resume normal activities immediately afterwards

## Benefits of this advanced measurement

Corneal properties can affect standard pressure readings. Understanding these factors helps the clinician judge your real risk of optic nerve damage more accurately.

- Useful for patients after laser vision correction or with unusual corneas
- Supports tailored treatment decisions in glaucoma care
- Helps track changes in corneal biomechanics over time
- Can be combined with other tests for a complete risk profile
