Objective perimetry has long been desired. Now, with more than 12 years research and over 17,000 exams performed, Konan introduces the objectiveFIELD analyzer (OFA®).  Estimated availability Q4 2019.

objectiveFIELD FAQs

Thank you for your interest in the objectiveFIELD Analyzer (OFA). The acquisition of this exciting new technology has very recently been completed and we are hard at work preparing to commercialize the device.

objectiveFIELD is FDA 510(k) Cleared and CE MARK activities have been initiated.

We will be updating the website as information becomes available.

In the meantime, we would be happy to add you to the OFA email list so that you are among the first to know about important updates  / product availability. Please scroll to the bottom of this page and complete the form or call +1 (949) 576-2200.

How does objectiveFIELD work?

A: It uses a novel stimulus strategy, an example of  which you can see here. Pupillary responses are measured objectively using infrared video cameras.

How long does a test take?
A: The current full threshold test is approx. 7 mins for both eyes (binocular test) There are shorter protocols (as short as 80 seconds) that will be available in the future, timing TBD.
How does objectiveFIELD compare to conventional perimetry?
A: It is objective, binocular, and very easy for patients to take and for techs to administer on patients. While it performs tests out to 30 degrees (29.5 degrees) and macular tests, OFA uses a completely different stimulus strategy  – here is a link to a video of an example of what the patient sees. Responses are measured objectively using a patented “Clustered Volley”, multi-focal pupil objective perimetry method. ObjectiveField stimuli cover more than 99% of the 30-2 retinal area, while SAP Goldman III stimuli only sample approximately 0.5% of the 30-2 area with the assumption that the remaining 99.5% of the non-sampled central area is well represented by the small stimuli.
How Does objectiveFIELD compare to the HFA?
A: The HFA was the predicate device used in the FDA 510(K).
Are there any disposables used?

A: No. There are no disposable parts. Similar to many diagnostic devices, the forehead rest can be sanitized in between patients using alcohol wipes.

Can the device accommodate smaller faces?
A: The human interface design is designed for a wide range of human morphology.
What refractive correction is needed?
A: Trial lenses are used for larger refractive errors.
What is the price of objectiveFIELD and when will it be available?

A: The device has not yet been commercialized, pricing and availability will be announced in Q3 2019.
