Battery performance is impacted by multiple variables.

Temperature: Ideally room temperature. Avoid exposure to excess temperatures.

Charge rate: Only use the charger supplied to ensure optimum charge rate

Depth & Frequency of charge / discharge cycles: Lithium ion batteries prefers

partial discharge to deep discharge, so it’s best to avoid taking the battery all the

way down to zero. Since lithium-ion chemistry does not have a “memory”, you do not harm the battery pack with a partial discharge.

Storage: Ideally your battery should be used regularly. However, if you’re going to store a backup battery for a long time, charge the battery halfway and then turn it off. Every six months charge it back to 50% and then turn it off again.

Expected useful life: The useful battery life of Lithium Ion batteries will be impacted by the variables above and will vary significantly from person to person. As a rule of thumb, a well-cared for Lithium Ion battery should achieve 80% of its capacity even after 2-3 years of regular usage.

The Vorotek O Scope has been designed to deliver the ideal level of magnification (2 or 3 dioptre) at a close-up working distance of 20-40cm. This is combination of magnification & working distance is ideal for almost all Ear, Nose & Throat procedures.

For the simple convergence system that O Scope is, it is proven to be counterproductive to have more magnification than that.Magnification (x) is inversely proportional to the working distance and affects the clarity/depth in the narrow cavity such as earcanal. Having an optical system to blow up the canal 4 or 5 times, leaves a little clarity and depth of the structures beyond second bend and was rejected by most ENT’s in the past. That is why the O Scope was designed to be a 3Diopter system, roughly magnifying up to x1.75. However, you are close enough to the ear to see everything and not too close, not to be able to provide effective earcare

A key benefit of the O Scope is the user can be and should be much closer to the patient compared to Loupes or an operating microscope. This improved proximity to the patient means less magnification is required to do the same job if you were further away. The ideal working distance for ear & nose work with the O Scope is around 25cm -30cm. The 3D works perfectly at this distance. ENT’s doing mouth work want to be a little further away and so they often prefer 2D which increases the working distance a little (around 40 cm).

The only option to achieve clarity/depth with more magnification is multi lens system that the full blown microscopes are.

The published range for the Interpupillary Distance (IPD) adjustment of the OScope is 58mm to 70mm. However, it is worth noting that there are some successful users, whose IPDs deviate approximately 2-3mm higher or lower than this range.

For instance, we have observed users with very narrow IPDs measuring between 55-56mm who have effectively utilised the OScope. While these users may experience a marginally smaller field of view, it does not impede their ability to clearly observe the ear canal.

O Scope is a true binocular convergence system, which is revolutionary concept in ear canal visualisation by portable means. No wonder >90% of Australian ENT Surgeons use O Scope in their clinics for grommet insertion and ear canal work. Originally developed by Dr John Vorrath MD, the aim was to deliver the optical benefits of an operating microscope with the convenience and affordability of a head-worn, fully portable device.  In the same way a microscope works, the Vorotek O Scope’s optical pathway converges the eyes to just 12mm apart.  This allows both eyes to reach the bottom of narrow cavities and deliver excellent depth perception.

The result is consistently improved diagnosis and more effective instrumentation. This Unique Converged Optical Pathway is what differentiates the O Scope from Loupes, which are unable to achieve depth perception in narrow cavities

Not sure if you can compare a convergence optical system that our headworn microscope is, with the loupes.

With the individual prisms on each eye, the dominant eye tends to form the image on the retina, giving you largely monocular optical perception. It is same as the Stenger effect for sound where if you put a headphone on your ears with a louder sound in one ear than the other, the brain only perceives it as monoaural sound in the ear with louder sound.

The Vorotek O Scope provides converged binocular vision and 3 dioptre magnification. This is essential to achieve the binocular vision and depth perception in narrow cavities. e.g. Ear, nose, throat. Converged optical pathways are also a feature of operating microscopes

3D model has a working distance of around 20-25 cm, which is ideal for the ear and nose work. For throat work, sometimes a longer working distance is required. 2D model has a longer focal length of 40-45cm and is suitable for throat work. However, it is largely dependent on personal preference as well.

Headband can be worn over your own prescription glasses and can be easily shared with colleagues. Specframe is idea for individual use. It comes with neutral glasses as standard but can easily be fixed on prescription glasses either by your own optician or we can organise that for you as well in with our partner optician.

If you are using Specframe, make sure you use sufficiently “high-index” plastic lens materials that bend light more efficiently. High index lenses are made up of thinner and lighter plastic materials that bend light more efficiently.

Setup is really simple and instructions are given in the technical manual here and/or see the setup videos here

If you are new to O Scope, it is best if you try to get your eyes adjusted to the optics before using it in clinic. So, it works better if you first try to just focus your eyes and head position to the view with some inanimate objects in the clinic and looking at the ears of friends and family. You should be able to have a great view right up to the eardrum if you move your head in, as you try to look past the second bend.

As the focus is fixed with O Scope, you will have to move your head slightly towards the ear (about an inch difference in head position between the view at the lateral end of the earcanal and at the eardrum), as you look further inside in the earcanal. When using the instruments, make sure that the tip of the instrument is well focused by adjusting your head position, according to where excatly in the ear you are. When near the eardrum, please keep in mind the usual 60 degree slant of the eardrum.

Again, 3D O Scope’s focal length is around 25-30 cm and it offers a magnification of around x1.75. It takes a few minutes to get used to the smaller size and the depth as clear as this. However, as you are close enough to the ear interms of the working distance, the overall effect is superb and you should fall in love with the clarity straightaway.
