Intraocular foreign body from a nylon line grass trimmer.

Nylon line grass trimmers are commonplace in America's lawn armamentarium. As their number has increased, so has the potential for ocular injury from objects thrown from these tools. A patient of ours was injured by an intraocular piece of nylon line thrown from one of these tools. The patient required removal of the foreign body, lensectomy, and anterior vitrectomy to rehabilitate her eye. This report again demonstrates the need for eye protection when using any type of lawn equipment. We think manufacturers of these products should label them to show that eye protection is necessary for the safe use of these tools.
