Cirrus 6000 Beats Siblings for Efficiency

The workflow efficiency of three Zeiss high definition optical coherence tomography (HDOCT) devices, the Cirrus 4000, 5000 and 6000, have been compared in a randomised, prospective, single-centre, clinical trial.

Reportedly the first workflow efficiency study to compare three OCT devices by the same manufacturer, it measured time taken for scan acquisition report generation. A technician imaged 43 subjects, primarily with retinal disease in at least one eye, in a randomised order on the same day. Patients were not dilated and were representative of those attending a general ophthalmology practice.

The scan acquisition duration on the Cirrus 6000 was significantly shorter than the Cirrus 5000 and Cirrus 4000, with faster speed observed in individual scans, and a common clinical scan protocol. This was the case regardless of patient age, (older subjects can be challenging and frequently require additional time).

The longest duration for a Cirrus 6000 was three minutes to scan both eyes, whereas the Cirrus 5000 and Cirrus 4000 were five and six minutes, respectively. This equates to a saving of at least 30 minutes per day for a 15-patient practice and at least 90 minutes per day for a 45-patient practice, helping decrease patient wait times and increase time for doctor consultation.

Additionally, the 6000 was 29% faster at saving reports for doctor analysis than the other devices. This increase in speed was achieved without compromising image quality.
