In certain usage environments, when the 3d oct-1 is used over a prolonged period of time, dust can penetrate into the optical system and adhere to the surface of the lens. this dust accumulates gradually over time and this can cause a whitish shadow artefact to occur in centre of the image and potentially create a blurry background. if this occurs, the reduced image quality is an obvious anomaly noticed during clinical assessment which cannot be mistaken for patient pathology.

Topcon Corporation will perform a retrofit to block the penetration points to prevent dust from entering into the optical system. In order to do this, Device Technologies will organise the return of affected machines to the manufacturer for the upgrade. A loan unit will be provided for the site whilst their machine is being upgraded. The corrective retro-fit action will be performed in a systematic manner, over a period of time due to the limited number of loan units available. Although affected systems may not exhibit any evidence of this artefact, it is recommended that all units undergo this preventative measure. Customers may continue to use their machine as usual until a loan unit is available for the site.
