The PachPen provides the following general features:
- Multi-segment high-resolution LCD screen with control buttons to provide an intuitive user interface
- Long-lasting lithium battery power source
- 18.4 cm x 3.2 cm x 3.2 cm (7 1/4” X 1 1/4” X 1 1/4”) size, and 85 g (3 oz.) weight make the unit very portable
- Ergonomic design that fits comfortably into the hand for fast and accurate measurements
- Allows entry of Intraocular Pressure (IOP) and provides Corrected IOP based on corneal thickness measurements
- The body of the PachPen is angled from the probe tip, and both the body and the tip have sighting lines that allow easy visualization of the cornea, facilitating both centration and perpendicularity
- User controlled speed of sound
- Display of measured corneal thickness, entered IOP, Corrected IOP, and average for all stored measurements
- Automatically capture and store up to nine measurements, along with the running average of all measurements taken
Measurements
The high accuracy of the PachPen measurements is provided by the following:
- High-resolution, real-time waveform analysis
- High-speed signal digitalization that acquires over 4,000 points per signal waveform
- Automatic gain control to acquire the optimum signal
- Highly sensitive 10.5 MHz composite probe
- 20 individual signals acquired and analyzed to produce each measurement
