The US Food and Drug Administration announced a Class I recall of lot no UD30654 of Healon D, an ophthalmic viscosurgical device (OVD) manufactured by Advanced Medical Optics Inc (AMO) of Santa Ana, California.

OVDs are viscoelastic materials used to maintain space in the eye during surgery. Typically, OVDs are pre-packaged in a syringe and are applied using a small tube.

On October 30, 2008, AMO voluntarily recalled all 4,439 units of Healon D lot no. UD30654 of Healon D, due to complaints of inflammation after eye surgery, including Toxic Anterior Segment Syndrome (TASS). At that time, AMO informed customers of the number and nature of adverse event reports associated with OVD from that lot, and included a fax reply form for quick communication.

However, as of December 3, 2008, AMO had retrieved only 964 units of the 1,450 that had been distributed in the United States.

AMO received 66 adverse event reports associated with the recalled products. Tests of this lot revealed elevated levels of endotoxin, which has been associated with post-operative intraocular inflammation and TASS.

TASS is a post-operative, acute inflammation of the anterior segment of the eye (the front third of the eye including the cornea, iris and lens). TASS has been linked to solutions and devices used during eye surgery, such as OVDs, intraocular lenses and irrigation solutions.

The FDA urges anyone in possession of any units from the recalled lot, whether units were purchased from the company or provided as a sample by a sales representative, to remove them from inventory, and contact AMO at 1-877-AMO-4Life to make arrangements for return. The lot number of the device is displayed on the side panel of each unit.
