The Occuity
PM1 Pachymeter
The world’s only non-contact, handheld optical pachymeter, the Occuity PM1 pachymeter will make it easier, faster and safer to diagnose glaucoma by measuring corneal thickness in just a few seconds.
NB. The Occuity PM1 is due to launch in 2023 after CE marking is achieved. Details on this page are subject to change /and are for guidance only.
The first of Occuity’s revolutionary handheld optical ophthalmic devices, the PM1 pachymeter allows both clinicians and technicians to take a corneal centre thickness measurement quickly and easily.
Simple to use, the PM1 pachymeter is held in front of the subject’s eye at a comfortable working distance. To take a measurement, the operator simply touches the screen to put the pachymeter in scanning mode and holds it up to the patient’s eye.
There is no need to anaesthetise or touch the eye, removing the risk of infection transmission and making the whole process much more comfortable, safer and quicker for both the operator and subject.
Features & Benefits
The Occuity PM1 pachymeter will provide the measuring and non-contacting capabilities of existing optical desktop devices at a price point comparable to the handheld contacting ultrasound devices.

Non-contact
A better clinician and patient experience
The PM1 pachymeter’s non-contact capabilities make it totally pain-free and a much better experience for both the clinician and the patient.
Accurate
Measure Corneal thickness, accurately, reliably and repeatably
In-house testing indicates the Occuity PM1 pachymeter will be capable of delivering reliable, repeatable measurements with a target accuracy of +/- 10 microns.
The PM1 will be undergoing clinical trials and CE certification in 2022.


Handheld
Desktop capability, handheld utility
The PM1 pachymeter’s compact design makes it easy to carry and store. You can use it handheld or if you prefer, in a slit-lamp mounted cradle, making it perfect for both clinical and non-clinical settings.
Reduce Chair Time
Results in just a few seconds
As the PM1 pachymeter is non-contacting, there is no need for anaesthetic eye drops. This significantly reduces the overall time it takes to make a measurement.


Easy to operate
Intuitive design means no training is required
The PM1 pachymeter’s touchscreen interface has been thoughtfully designed making it easy and intuitive to use. Clinical staff and technicians can become proficient with just a few minutes of practice.
Safer
Reduced risk of disease transmission and injury
With its generous working distance, the PM1 never touches the eye – removing the potential risk of cross infection and accidental damage to the cornea. In particular, the PM1 pachymeter’s non-contacting capability enhances COVID-19 safety.


No consumables
No waste, No waiting
Removing the need to contact the eye, removes the need for anaesthetic eye drops, waiting and cleaning times. This reduces costs, waste, downtime, and the risk of damaging equipment through cleaning. The PM1 pachymeter was designed with sustainability in mind. A quick wipe to remove any dust from the lenses is all that is required.
Wireless Charging
Ready when you need it
The Occuity PM1 pachymeter will always be ready thanks to the innovative wireless charging cradle.
The cradle also contains a built-in reference artefact so the device can perform a basic self-test before use.

Cost Effective
Desktop Performance, Handheld Pricing
Enjoy the accurate measuring and non-contact capabilities of expensive optical desktop devices at a price point comparable to existing contacting ultrasound devices.

Portable
Take it with you, safe and secure
The PM1 pachymeter's robust travel case (included) safely and securely holds the PM1, its charging cradle and Instructions for Use (IFU). Not only does the case provide protected storage, it allows the PM1 to be safely taken on appointments.
Included in the case is the charging cradle, cleaning cloth and Instructions for Use (IFU).

Precision Optical System
The patented optical technology within the Occuity PM1 pachymeter uses a tightly focused beam of light to scan the eye. When the focus passes through a surface a bright reflection is seen which allows the meter to know exactly where that surface is. The PM1 pachymeter collects the reflections from the front and back surfaces of the cornea, allowing a very precise measurement of corneal thickness.
With our expertise in optics and miniaturisation, Occuity’s proprietary technology ensures that in addition to being accurate, the PM1 pachymeter is also compact and very cost-effective.
The following videos show the PM1 in operation and an existing ultrasound pachymeter being used to take a corneal measurement. As you can see, the entire process takes seconds with the PM1, whilst the ultrasound takes a considerable amount of time and uses disposable resources.
SL1 - Slit Lamp Adapter
Use the PM1, at your convenience
Whilst the PM1 Pachymeter is perfect for handheld use, it can also be used on a slit lamp thanks to the simple but effective SL1 slit-lamp adapter.
The SL1 slit-lamp adapter can be purchased separately
