Manufacturers of punctum plug technology continue to improve their offerings, making their products easier to insert with better retention. This overview highlights new punctum plugs or plugs modified over the past year.
Among those with new products is FCI Ophthalmics, which began selling the Snug Plug last fall. "It's a one-size-fits-all punctal plug, and I stress punctal because it fits in the punctum and is not intracanalicular," said Anne Bohsack, vice president. "The Snug Plug has a collar that rests on the eyelid surface so you can have control over it, you can move it if necessary, and you know that it's there."
In mid-2006, Medennium introduced a second-generation design of its SmartPlug, based on 5 years of clinical experience, according to Steven Zhou, PhD, vice president of research and development.
Medennium also has introduced Xsorb, an absorbable plug effective for up to 90 days. This plug comes in 0.3-, 0.4-, and 0.5-mm diameters and is indicated for temporary alleviation of dry eye symptoms, Dr. Zhou said.
