In 9\/11 eyes, multiple caterpillar hairs could be detected in the superficial and deeper cornea. Hair removal was attempted in 8\/9 eyes; in one eye hair removal was impossible due to its deep stromal location (lost-to-follow-up). Entire hair removal was successful in 2\/9 eyes, hence, six eyes with persisting hairs within the cornea were followed. Stromal haze developed adjacent to the hairs in all eyes and individual hairs disappeared (n\u2009=\u20094) and\/or showed migration within the cornea (n\u2009=\u20093). Until 2023, the number of patients with OPC-associated ocular complaints decreased continuously.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Ophthalmologists should be aware of the possibility of caterpillar hairs in patients with acute eye symptoms after outdoor acitivities, especially in early summer; the incidence may fluctuate, though.
