Perforating eye injury while working with a powered mower in two face-shield wearers

Purpose : To report two cases who were hit by flying foreign body in the eye while working with power grass cutters even though they were wearing a face shield. Cases : Both were males aged 51 and 61 years respectively. In the first case, the foreign body penetrated the shield, a broken piece of which injured the left cornea. He was successfully treated by suture of the corneal wound and vitrectomy. In the second case, a foreign body injured the left cornea after passing through the space between the shield and his face. He was successfully treated by suture of corneal wound, phacoemulsification-aspiration, and implantation of intraocular lens. Conclusion : Wearing a face shield may not fully protect the eye when working with power grass cutter. The eyes can be better protected by eyeglasses made of polycarbonate.
