The description details a traditional opto-electronic system with an on-board microprocessor converting photodiode readings to IOP. There is no mention of AI, ML, or related concepts.
No.
The device is indicated for "measuring intraocular pressure ... to aid in the screening and diagnosis of glaucoma," not for treating or preventing a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "to aid in the screening and diagnosis of glaucoma." This indicates a diagnostic purpose.
No
The device description explicitly details hardware components such as an air generation system (vacuum diaphragm pump, air reservoir, solenoid valve), a light source, and an opto-electronic platform, indicating it is not a software-only device.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The device description clearly states that the Pulsair Tonometer measures intraocular pressure without contacting the eye. It uses a puff of air and light reflection to determine the pressure within the eye. This is a direct measurement on the living body, not an analysis of a biological sample taken from the body.
- The intended use is for measuring intraocular pressure. This is a physical measurement of a physiological parameter, not a test performed on a specimen to diagnose a condition.
Therefore, the Pulsair IntelliPuff and Pulsair Desktop Tonometers are medical devices, but they do not fit the definition of an In Vitro Diagnostic device.

Device Description
The Keeler Pulsair Tonometer product family are non-contact tonometers and are used to measure intraocular pressure without contacting the eye to aid with the screening and diagnosis of glaucoma. The product family consists of the Pulsair Intellipuff (Hand Held device) and the Pulsair Desktop which is mounted on a desk. The Pulsair Intellipuff Tonometer has been designed using the same ergonomics as the predicate device described in 510(k) submission K990257 whilst the Pulsair Desktop Tonometer ergonomics have been adapted to suite the Desktop mounted market place. Both products use the same concept of measurement as the predicate device and contain many common components. All of the products consist of an air generation system in the form of a vacuum Diaphragm pump, an air reservoir, a solenoid valve, a light source and an opto-electronic platform which is used for position detection and IOP measurement.
The basic concept of operation is the same. The user positions the instrument close to the patient's cornea using a targeting system. As the user moves the instrument closer to the patient, the reflection off the cornea from the built in light source increases until the predefined firing thresholds on the built in photodiodes have been met. Once this condition has been met, a quantised puff of air is automatically projected toward the patient's cornea. As the cornea flattens due to the force of the puff of air, the light being reflected off of the cornea changes shape which in turn changes the profile of the light being reflected back onto the photodiodes. The rate of change of this reflection is monitored by the photodiodes and converted into intraocular pressure in units of mmHg by the on board microprocessor.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Clinical Trial: A new independent clinical study was conducted on the Keeler Pulsair IntelliPuff Tonometer to show the design compliance of the Pulsair Tonometer against a reference Tonometer (Goldmann Tonometer). The study requirement for design compliance as specified in the ANSI Z80.10-2003 and ISO 8612:2001 stipulates that no more than 5% of the paired differences between the reference Tonometer and the Pulsair Tonometer should be outside the ±5mmHg tolerance in the three IOP ranges. The study showed that the readings obtained using the Pulsair Intellipuff were not significantly biased relative to those obtained using the Goldmann Tonometer, and the paired differences between the Intellipuff and Goldmann were within ±5mmHg for over 95% of the eyes tested. The Pulsair Intellipuff readings tended to fall slightly below the Goldmann readings at IOP's exceeding 30mmHg, but the difference was not clinically significant.
To demonstrate equivalence between the Pulsair Intellipuff Tonometer and the Pulsair Desktop Tonometer an additional small scale trial was conducted within a clinical environment on 28 eyes. The trial compared readings between the Pulsair Intellipuff, Pulsair Desktop and the Goldmann Tonometer. The results obtained from the trial demonstrate that the readings obtained using the Pulsair Desktop Tonometer were not significantly biased relative to those obtained using the Goldmann Tonometer, and the paired differences between the Desktop and Goldmann were within ±5mmHg for over 95% of the eyes tested. Further the results obtained from the trial demonstrate that the readings obtained using the Pulsair Desktop Tonometer were not significantly biased relative to those obtained using Pulsair Intellipuff, and the paired differences between the Desktop and Intellipuff were within ±5mmHg for over 95% of the eyes tested. We therefore conclude that the Pulsair Intellipuff and Pulsair Desktop tonometers are clinically equivalent.
Bench Testing: The performance of the Pulsair Desktop and Pulsair IntelliPutf Tonometer were tested under laboratory test conditions using and industry approved test set-up. The results of bench testing show that Keeler Pulsair Intellif and Keeler Pulsair Desktop do produce repeatable and comparable measurements.

7. Technology Characteristics and Equivalence to Predicate Device
. .
3
A description of the main changes introduced in the Pulsair IntelliPuff and Pulsair desktop in relation to the FDA approved predicate device Keeler Pulsair 3000 Non-Contact Tonometer are as follows:-
-
A sub-miniature Halogen bulb (note: visible light filtered out. Wave length of 680nm and above used) is replaced by a 720nm LED.
-
Air puff control introduced i.e. softer puff used to obtain measurements on patients with IOP less than 23mmHg. This improves patient comfort.
-
Photo sensors changed due to obsolescence of previously specified components.
-
Smaller and quieter pump used to reduce environmental noise.
-
Introduction of a user menu that allows the practitioner (user) to set the instrument to individual requirements.
-
The instrument continuously compares measurements and when enough measurements have been taken, the instrument indicates this fact to the user via audible sound. This ensures that the patient does not receive more measurements than is absolutely necessary.
9. Technological Equivalence between Pulsair IntelliPuff and Pulsair Desktop
Keeler Pulsair IntelliPuff and Pulsair Desktop have similar technological features with regards to the optical system, optoelectronic devices, electronics, pneumatic system, contained software, measurement technique, calibration technique, safety, effectiveness and intended use.
Minor differences between Pulsair Desktop and Pulsair IntelliPuff are listed in the table below:
| Pulsair IntelliPuff | Pulsair Desktop |
|---|---|
| Hand Held | Desk mounted & Joystick driven |
| Operator view through an eye | |
| piece | Operator view through a Camera and |
| TFT Screen | |

| Instrument goes to sleep mode | |
| on returning the hand unit to its | |
| cradle | Instrument sleeps after 5 minutes of |
| inactivity | |
| Left/right eye selection is | |
| manual | Left/Right eye selection is automatic |
10. Calibration
The Pulsair Tonometer is an eye pressure measuring device. For this purpose, the system is equipped with an internal pressure transducer which is calibrated against an external pressure transducer, which in turn is calibrated against a known standard. The calibration process involves calibrating the optical and pneumatic systems of the instrument in various stages. The Keeler Pulsair IntelliPuff and Desktop are calibrated in the same manner as the predicate device Pulsair 3000 non-contact Tonometer.

11. Performance testing
Device performance: Risk management completed as per BS EN ISO 14971:2001(IntelliPuff) and BS EN ISO 14971:2007 (Desktop), which analyses and evaluates risks associated to the product and preventive actions to mitigate each risk. The Pulsair IntelliPuff and the Pulsair Desktop have been tested in accordance with BS EN ISO 15004 -2:2007 and are within the limits specified for Optical radiation Hazard. The Pulsair IntelliPuff and Desktop uses a medically approved Power supply (Keeler Ref: EP29-3277) which is compliant with BS EN 60601-1 and 60601-1-2. Pulsair Desktop and IntelliPuff have been tested for electrical safety to BS EN 60601-1 and Electromagnetic compatibility to BS EN 60601-1-2.
Software Development & Performance: Pulsair IntelliPuff and Pulsair Desktop software are derivatives of Pulsair 3000 non-contact Tonometer which was granted FDA approval in 1999. The algorithm for IQP calculation remains the same. Keeler sub-contracted the further development of this software for the Pulsair Intellipuff to an external development organisation. The organisation were employed to develop the functionality and usability of the existing software based on an initial Product Design Requirements Specification developed by Keeler for the Pulsair Intellipuff non contact Tonometer. They generated the subsequent documentation and conducted the various development activities associated with software and hardware development. All change control was managed by them until transfer into the Keeler QMS in 2007. All subsequent changes have been controlled under the Keeler Change Control Process. The software for the Pulsair Desktop non contact Tonometer was designed under Keeler design and development processes. The products have had numerous validation and verification activities conducted including bench and clinical testing. The results are included in this 510(k) submission.
The software for both the Pulsair Intellipuff and Pulsair Desktop are considered 'Moderate' level of concern.
Clinical Trial: A new independent clinical study was conducted on the Keeler Pulsair IntelliPuff Tonometer to show the design compliance of the Pulsair Tonometer against a reference Tonometer (Goldmann Tonometer). The study requirement for design compliance as specified in the ANSI Z80.10-2003 and ISO 8612:2001 stipulates that no more than 5% of the paired differences between the reference Tonometer and the Pulsair Tonometer should be outside the ±5mmHg tolerance in the three IOP ranges. The study showed that the readings obtained using the Pulsair Intellipuff were not significantly biased relative to those obtained using the Goldmann Tonometer, and the paired differences between the Intellipuff and Goldmann were within ±5mmHg for over 95% of the eyes tested. The Pulsair Intellipuff readings tended to fall slightly below the Goldmann readings at IOP's exceeding 30mmHg, but the difference was not clinically significant.
To demonstrate equivalence between the Pulsair Intellipuff Tonometer and the Pulsair Desktop Tonometer an additional small scale trial was conducted within a clinical environment on 28 eyes. The trial compared readings between the Pulsair Intellipuff, Pulsair Desktop and the Goldmann Tonometer. The results obtained from the trial demonstrate that the readings obtained using the Pulsair Desktop Tonometer were not significantly biased relative to those obtained using the Goldmann Tonometer, and the paired differences between the Desktop and Goldmann were within ±5mmHg for over 95% of the eyes tested. Further the results obtained from the trial demonstrate that the readings obtained using the Pulsair Desktop Tonometer were not significantly biased relative to those obtained using Pulsair Intellipuff, and the paired differences between the Desktop and Intellipuff were within ±5mmHg for over 95% of the eyes tested. We therefore conclude that the Pulsair Intellipuff and Pulsair Desktop tonometers are clinically equivalent.
5
Bench Testing: The performance of the Pulsair Desktop and Pulsair IntelliPutf Tonometer were tested under laboratory test conditions using and industry approved test set-up. The results of bench testing show that Keeler Pulsair Intellif and Keeler Pulsair Desktop do produce repeatable and comparable measurements.
12. Conclusions
Based on the product verification and product validation activities we conclude that the Pulsair Intellipuff and Desktop Tonometers are substantially equivalent to the predicate device described in 510(k) K990257. The clinical trials conducted demonstrate the measurements obtained by the product are not significantly biased relative to those obtained by the established, gold standard Goldmann Tonometer and with no adverse customer feedback from sales of units throughout the EU demonstrate that both products are safe and effective.
