What a report is

A report is not proof that the device was the cause of the event.

FDA says:

Adverse event reports submitted to FDA do not undergo extensive validation or verification. Therefore, a causal relationship cannot be established between product and reactions listed in a report. While a suspected relationship may exist, it is not medically validated and should not be the sole source of information for clinical decision making or other assumptions about the safety or efficacy of a product. Additionally, it is important to remember that adverse event reports represent a small percentage of total usage numbers of a product. Common products may have a higher number of adverse events due to the higher total number of people using the product.

FDA also says:

Although MDRs are a valuable source of information, this passive surveillance system has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data. In addition, the incidence or prevalence of an event cannot be determined from this reporting system alone due to potential under-reporting of events and lack of information about frequency of device use.

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.

Reports on file

From February 2015 to September 2026, FDA received 2,428 medical device reports that name the brand AcrySof IQ Natural Singlepiece IOL. A brand name is as the reporter or the manufacturer wrote it, so one product can have more than one spelling.

FDA received 105 reports in the 12 months to September 2026 and 165 in the 12 months before. FDA releases MAUDE data every month. Reports can arrive months after an event, so the newest months grow in later releases.

Of the 3,444,740 device reports that FDA received in the 12 months to September 2026, 105 (under 0.1%) name the brand AcrySof IQ Natural Singlepiece IOL. Manufacturer reports were 100% of the reports that name this brand and 94.9% of all device reports.

The number of people who use the product is not in the data. A count is not a rate. A count of reports is not a count of events or of patients, because one event can have more than one report.

What an MDR is

A medical device report: one submission to FDA about one event. It has the brand name, the generic name, the manufacturer, the product code, the event type and coded problems. Manufacturers and user facilities must send reports.

Data version

openFDA MAUDE release of 23 Oct 2026. Reports received through 30 Sep 2026.
