Adopting new technology without sacrificing practice space

When optometrists make essential choices about including expertise to their apply, flooring house is usually a limiting issue. We search to equip ourselves to supply sufferers with the perfect care potential, and this typically entails weighing the impact of varied units on workplace format and affected person stream.

Eye care professionals have to do what is correct for the affected person. We construct affected person belief and we work onerous to maintain it. If a affected person has a situation we can’t confidently diagnose—and we don’t have the flexibility to carry out crucial additional testing—we are going to both refer the affected person out solely for testing or ship them to a specialist for care.

It could then prove that the issue might have been dealt with inside our workplace. And that might have saved the affected person the effort of getting to journey to a brand new workplace and familiarize themselves with new workers.

Because the tempo of expertise growth continues to speed up, increasingly units turn out to be out there that we might undertake. The excellent news is that, on the whole, the dimensions of units is reducing.

I’ve been within the trade for over 25 years and bear in mind coaching on the primary Humphrey Discipline Analyzer (HFA) by Zeiss, which was 5 ft tall and 5 ft extensive, with a giant bowl. Although nonetheless substantial, present HFA units are considerably smaller (see Determine 1). Lasers additionally used to require a big room. Now they’re typically moveable and could be taken from workplace to workplace.

The introduction of wearable units takes this dimension discount development to a brand new stage. In my apply, I exploit the Heru headset with visible area (see Determine 2), distinction sensitivity, and colour imaginative and prescient exams.

The platform is run by means of a headset that may be held on the wall. It creates its personal darkish surroundings, so no devoted darkish room is required. Which means including this highly effective expertise has no impression on flooring house.

Portability upside

The portability of latest diagnostic expertise, such because the Heru headset with a number of imaginative and prescient diagnostic exams, is extremely helpful to eye care professionals, as testing could be carried out on a affected person anyplace inside a apply.

As we navigate the COVID-19 pandemic, this offers clinicians the flexibleness wanted to keep away from transporting a affected person from room to room. The expertise involves the affected person, who could be in a clear room with the door closed.

One other essential issue is that the affected person is just not contaminating an extra testing room. As soon as a room is contaminated, it’s down till it’s cleaned. This entails a extra thorough, time-consuming clear than the one carried out earlier than the arrival of COVID-19, and testing rooms can turn out to be bottlenecks.

As practices sought to proceed functioning easily amongst new distancing and cleansing necessities, one step was typically to take a extra problem-focused method to exams.

Suppliers would ask whether or not an examination actually wanted to be completed throughout the go to or whether or not it will be potential to skip bringing the affected person to a testing room.

At our apply, we additionally moved tools round, anticipating the checks sufferers tended to want on the similar time, and attempting to place these units in the identical room.

On this surroundings, the flexibility to deliver devices right into a affected person’s examination room is of nice worth. It makes it simpler to hold out a broader vary of screening and testing and reduces the necessity to prohibit oneself to a reactive method.

If the affected person has a household historical past of glaucoma, I can have my technician run a fast visible area utilizing the Heru headset. I can even shortly do an unplanned screening if a affected person mentions complications and I need to rule out neurological elements.

A greater use of assets

Ready rooms typically characterize underutilized house inside a apply. With the introduction of wearables that create their very own testing surroundings, the ready room can turn out to be a testing space. That is additionally true of the dilation space, which is now typically not solely a testing station however a therapy space.

In small practices, for instance, meibography could be carried out within the dilation space. If applicable for the stream, meibomian gland therapy can even observe in the identical location through the use of both a conveyable or mounted digicam system.

TearCare (Sight Sciences) is a wearable eyelid expertise that gives warmth remedy, which practitioners can use on sufferers within the dilation space or examination room (see Determine 3). The guide expression of the meibomian glands will also be completed within the examination room through the use of a slit lamp.

Workers availability is a restricted useful resource in all practices, although it’s not associated to sq. footage. Wearables such because the Heru headset release technicians to hold out helpful actions within the apply whereas within the room with affected person. Previously, a visible area check required a darkish room, and the technician was sitting at nighttime and couldn’t multitask.

With the Heru headset platform, sufferers can placed on the headset and their surroundings will likely be sealed (see Determine 4). The platform includes a digital information that leads sufferers by means of the checks, whereas real-time gaze monitoring throughout the platform confirms the affected person’s fixation is all the time applicable.

Affected person-driven testing permits the technician to finish different duties, reminiscent of updating information, coming into medicine into the system, or ordering contact lenses.
Whereas the technician nonetheless must be within the room, they will nonetheless perform further actions.


One other development is multifunctionality. All kinds of diagnostic exams are being mixed into 1 system.

Optical coherence tomography (OCT) units are incorporating cameras, making it potential to seize a picture of the retina and the OCT. New OCT units are additionally in a position to make each anterior and posterior section photographs, with wide-angle imaging. Additional mixtures embody infrared autorefraction units which have digicam or meibography capabilities.

For glaucoma prognosis and monitoring, the Ocular Response Analyzer G3 (Reichert) measures each corneal hysteresis and corneal compensated IOP, giving a extra full predictor of glaucoma development than both IOP alone or IOP along with corneal thickness (see Determine 5 for the same system). The FAT1 (Falck Medical) measures ocular profusion along with IOP, ocular pulse amplitude, and the pulsatile drive of the central retinal artery.

Multifunctionality is being mixed with wearability. The Heru platform provides suprathreshold and full threshold visible fields, distinction sensitivity testing, and colour imaginative and prescient screening (each Ishihara and Farnsworth D-15 prolonged colour imaginative and prescient checks). The corporate has additionally simply added a brand new “quick sample” suprathreshold visible area check that takes solely 20 seconds.

After I first started utilizing Heru for visible area testing, I used the platform on a affected person with identified glaucoma and did an HFA visible area on the identical day. This confirmed me how constant the outcomes and the printouts have been. The digital platform has been proven to have a powerful correlation to the gold customary HFA.1

I just like the platform’s distinction sensitivity testing functionality, as a result of some sufferers are available in who’ve hassle seeing at evening. This often has to do with decrease macular pigment density, which I measure within the palm of the affected person’s hand with the Pharmanex BioPhotonic scanner (Determine 6).

That is one other system that is ready to be moved. I do fairly a bit of labor with nutraceuticals, so if I’ve recognized an issue with distinction sensitivity and the BioPhotonic scanner, I can begin sufferers on a nutraceutical after which see if their distinction sensitivity and pores and skin carotenoid ranges change.

Moreover, lenses now exist that assist with colour imaginative and prescient issues. I can use the Heru platform for colour imaginative and prescient screening to establish sufferers who may profit.

These VR platforms aren’t only for a youthful affected person inhabitants. Heru’s system has been clinically examined on sufferers between the ages of 15 and 95, and I’ve discovered that the checks are so intuitive that virtually anybody, at any age, can full them.

Two of the primary sufferers I examined with the platform, who have been of their 60s or 70s, stated they completely loved the interactivity.

A promising outlook

The long run seems to be vibrant for wearables. I envisage a state of affairs during which the affected person arrives within the ready room and a technician comes out with a wearable diagnostic system, enabling the affected person to stay sitting with out having to maneuver to an examination room.

A spread of screening checks could be carried out on the affected person to incorporate visible acuities, colour imaginative and prescient, pupil evaluation, and a fast screening visible area. As these are being uploaded to the system, the technician walks again and does a screening OCT or takes a photograph of the affected person’s optic nerve.

By the point the technician sits within the room with a affected person, they have already got an summary of preliminary information that may be shared when the doctor enters the examination room.

The quicker and extra environment friendly screenings and diagnostics are, the extra practical it’s to carry out them on sufferers not demonstrating points with their imaginative and prescient. Early prognosis of progressive eye situations permits optometrists to successfully deal with the illness.

Wearable diagnostic platforms and multifunctional units facilitate a extra environment friendly apply workflow and make it potential for even these with a small house to have an intensive assortment of devices with elevated diagnostic capabilities.
