The postoperative pain of ophthalmic surgery has been widely concerned in recent years. Some patients show
enlarged painful areas and neurophotophobia postoperatively. This abnormal increase in noxious irritant signals
after surgery is called hyperalgesia. The development of hyperalgesia can result in delayed postoperative recovery
for patients. In addition, hyperalgesia can also cause discomfort for patients, and induce patients to use more
analgesics, which can have related side effects. TRPV1/TRPA1 is a nociceptor, which can be specifically activated
by nociceptive stimuli to induce hyperalgesia. Nevertheless, the pathogenesis of hyperalgesia after ophthalmology
surgery has not been fully elucidated, and the molecular signal pathway of how TRPV1 sensitizes and causes
hyperalgesia is not yet clear.
