FDA's MAUDE database holds 493 reports that name the brand "Lasik" (lasik), received between April 2000 and August 2026; the manufacturer given most often on reports is Lasik. Spellings of one product vary from report to report.

7 reports arrived in the 12 months to August 2026, down 61% from 18 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 (90.3%), other (4.5%) and malfunction (1.8%); across all excimer laser system reports (product code LZS) death is recorded in 0.1% and malfunction in 14%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are insufficient device problem information (41.8%), patient-device incompatibility (6.9%) and device operates differently than expected (5.3%). The patient problems coded most often are visual impairment, dry eye(s) and halo. 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."

Through FDA MedWatch (Form FDA 3500 for health professionals and consumers), or to the manufacturer. See the guide on how to report.

Where this comes from. Counts are built from the openFDA Device Adverse Event (MAUDE) bulk export released 28 Sep 2026, which holds reports FDA received through 31 Aug 2026. Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
