Working as an assistance under a certified ophthalmologist has had its own benefits and I sure have understood a lot about how eye specialists are able to give the best treatment to their patients. So many years of study and practice has given them the ease to handle with patients and their apprehensions on getting eye treatment done. There are also other things – instruments – ophthalmic instruments that are a huge assistance when it comes to treating complicated operations and are of extreme help to the doctor.


Below I am sharing some of the optometric equipment I think you should know about so that you are aware of what is treating you next time you visit your doctor:

Ø  Retinal Camera

The retinal camera is a specialized, low-power microscope equipped with a camera that has been designed to take pictures of the interior surface of the eye. This allows doctors to take a close look at the patient’s retina, macula, optic disc, posterior pole and other parts of the eye. Today’s retinal cameras are equipped with digital cameras that provide high definition photographs for doctors to examine. All of this data obtained from retinal cameras helps doctors/ophthalmologists to diagnose and monitor the advancement of the eye disease.

Ø  Photocoagulation Laser

A corneal cell counter is optometric equipment which is another type of advanced imaging microscope used by ophthalmologists to examine a patient’s internal eye structures. Unlike the retinal camera, however, a corneal cell counter employs advanced spatial techniques to render the images it takes as three-dimensional structures. Ophthalmologists can then use these 3D renditions to analyze and monitor diseases. Many of today’s corneal cell counters can also conduct automatic cell-analyses and other analytical functions to help detect ailments.

Ø  Wavefront Aberrometer

A wavefront aberrometer is a piece of equipment that combines different kind of imaging technologies, including pupillometry, keratometry, wavefront imaging, autorefraction and topography. The job of the wavefront aberrometer is to detect if there are any aberrations in the eye. The images obtained are displayed on an LCD screen at high-contrast, so that the aberrations can be easily zeroed down on and easily analyzed. 

Ø  Laser Ophthamoscope

I am sure you must have seen at least an ophthalmoscope. They are shaped very small, handheld devices that the doctors use to shine a light into your eyes during routine physical exams. The ophthalmoscope allows doctors to take a look on the inside of your eye to make sure it looks healthy. Laser ophthalmoscopes are advanced models of traditional microscopes that use laser light absolute detail and accuracy.

Getting ready for cloud data-driven healthcare

Getting ready for cloud data-driven healthcare
 Joe Gaska, CEO of GRAX, tells us how healthcare providers can become cloud-based and data-driven organisations

As healthcare continues to recognise the value of data and digital transformation, many organisations are relying on the cloud to make their future-forward and data-centric thinking a reality. In fact, the global healthcare cloud computing market was valued at approximately $18 billion and is expected to generate around $61 billion USD by 2025. 

At the forefront of these changes is the rapid adoption of cloud-based, or software-as-a-service (SaaS), applications. These apps can be used to handle patient interactions, track prescriptions, care, billing and more, and the insights derived from this important data can vastly improve operations, procurement and courses of treatment. However, before healthcare organisations can begin to dream about a true data-driven future, they have to deal with a data-driven dilemma: compliance. 

Meeting regulation requirements

It’s no secret that healthcare is a highly regulated industry when it comes to data and privacy – and rightfully so. Patient records contain extremely sensitive data that, if changed or erased, could cost someone their life. This is why healthcare systems rely on legacy technologies, like Cerner and Epic EHRs, to manage patient information – the industry knows the vendors put an emphasis on making them as secure as possible.

Yet when SaaS applications are introduced and data starts being moved into them, compliance gets complicated. For example, every time a new application is introduced into an organisation, that organisation must have the vendor complete a BAA (Business Associate Agreement). This agreement essentially puts the responsibility for the safety of patients’ information — maintaining appropriate safeguards and complying with regulations — on the vendor.

However, even with these agreements in place, healthcare systems still are at risk of failing to meet compliance requirements. To comply with HIPAA, U.S. Food and Drug Administration 21 CFR Part 11 and other regulations that stipulate the need to exercise best practices to keep electronic patient data safe, healthcare organisations must maintain comprehensive audit trails – something that gets increasingly difficult when data sits in an application that resides in the vendor’s infrastructure.

Additionally, data often does not stay in the applications – instead healthcare users download, save and copy it into other business intelligence tools, creating data sprawl across the organisation and exposing patient privacy to greater risk. 

With so many of these tools that are meant to spur growth and more effective care creating compliance challenges, it begs the question: how can healthcare organisations take advantage of the data they have without risking non-compliance?

Data ownership

Yes, healthcare organisations can adhere to regulations while also getting valuable insights from the wealth of data they have available. However, to help do this, organisations must own their data. This means data must be backed up and stored in an environment that they have control over, rather than in the SaaS vendors’ applications.

Backing up historical SaaS application data directly from an app into an organisation’s own secure cloud infrastructure, such as AWS or Microsoft Azure, makes it easier, and less costly, to maintain a digital chain of custody – or a trail of the different touchpoints of data. This not only increases the visibility and auditability of that data, but organisations can then set appropriate controls around who can access the data.

Likewise, having data from these apps located in one central, easily accessible location can decrease the number of copies floating around an organisation, reducing the surface area of exposure while also making it easier for organisations to securely pull data into business intelligence tools. 

When healthcare providers have unfettered access to all their historical data, the possibilities for growth and insights are endless. For example, having ownership and ready access to authorised data can help organisations further implement and support outcome-based care. Insights enabled by this data will help inform diagnoses, prescriptions, treatment plans and more, which benefits not only the patient, but the healthcare ecosystem as a whole. 

To keep optimising and improving care, healthcare systems must take advantage of new tools like SaaS applications. By backing up and owning their historical SaaS application data, they can do so while minimising the risk to patient privacy or compliance requirements. Having this ownership and access can propel healthcare organisations to be more data-driven – creating better outcomes for everyone.
