What this means for you

Our assessment, not the agency’s: severity 3/5 (High).

Our severity reasoning: The recall is classified as FDA Class II, and the defect involves incorrect medical data (IOL power) which poses a risk of harm to patients, but no injuries or illnesses have been reported in the source text.
