Medical laser device recalled for inadequate safety operating instructions
Ithera Medical is recalling the MSOT Acuity Echo medical laser device worldwide due to inadequate instructions for safe operation. Previous user manuals contained an incorrect Nominal Ocular Hazard Distance value.
What this means for you
Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.
Our severity reasoning: FDA Class II recall with no reported illnesses or injuries. The hazard involves inadequate safety instructions for a Class 4 medical laser device with an incorrect critical safety parameter (NOHD). This represents a significant risk of eye injury, meeting the rubric criterion for risk-of-harm products without reported injury.
