1,960 medical device reports received by FDA name the brand "Tecnis 1 Multifocal" (multifocal iols); the manufacturer given most often on reports is Abbott Medical Optics; received from January 2012 to December 2020. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (93.5%) and malfunction (6.4%); across all lens, multifocal intraocular reports (product code MFK) death is recorded in 0% and malfunction in 16.6%. Event type is the reporter's classification of the report, not a verified outcome.

The patient problems coded most often are halo, blurred vision and visual disturbances. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
