角膜神经

English: Corneal Nerves, Corneal Innervation

中文： 角膜表层感觉神经主要来自三叉神经眼支，密度高、痛觉敏锐。泪膜局部破裂或浅层点状损伤时，轻微刺激即可引发闪电样、瞬间消失的刺痛。

English: Sensory fibers to the cornea arise mainly from trigeminal V1 and are highly pain-sensitive. Tear-film breakup or superficial punctate injury can fire a lightning jab that fades almost immediately.
