If it’s not iLink®,
it’s not FDA approved

Don’t settle for less. There are several unapproved cross-linking procedures that healthcare providers might recommend or use without your knowing. These unapproved drugs and devices can put your patients’ safety, as well as your and your practice’s reputation, at risk.
Peschke Trade GmbH Import Alerts
The FDA has issued import alerts that include Peschke cross-linking devices and riboflavin. These products are illegal for importation and sale in the United States unless they are for a clinical investigation that is part of an FDA-approved investigational new drug (IND) application.

Not all cross-linking procedures are the same
Using any drug and device combination for corneal cross-linking other than iLink® is not just off-label,* it’s unapproved.†
The following chart compares the benefits of iLink® with the risks of unapproved cross-linking. Keep scrolling to see more unfold.

Unapproved devices may be modified or illegally imported with no postmarket surveillance1 |
