Photographs of the stung cornea in diffuse/slit illumination during approximately 1 month of follow-up. (A-C) Twenty hours after the injury: the deeply embedded stinger and the corneal epithelial defect are apparent around the site of injury. (D-F) Day 2 of follow-up (ie, the operation date). Note the corneal infiltration and edema, which led us to remove the stinger surgically. (G and H) Fourteen days after the operation: (G) before suture removal; (H) after suture removal. The infiltration is markedly reduced and the corneal epithelial defect is relatively healed. (I) One month after the operation: slight subepithelial scarring remains around the area of the stinger.

A 5 x 5 mm2 corneal epithelial defect was notable at the site of the sting (Figure 1A-C). External removal of the stinger was not possible because the tip of the stinger was not accessible (Figure 1C). Over the ensuing 2 days, corneal stromal infiltration and edema developed around the stinger site (Figure 1D-F), and visual acuity decreased to 100/200. Of note, the suture was removed 14 days after surgery ( Figure 1G and H). However, slight subepithelial scarring remained around the area of the sting (Figure 1I).
A demonstration of our surgical procedure (A-D: four steps) in removing the deeply embedded stinger on the second day of follow-up.

Thereafter, surgical removal of the stinger was suggested (Figure 2).
