This study was conducted at the Tianjin Medical University Eye Hospital (Tianjin, China) between March 2021 and September 2021. Twenty-six patients with unilateral mild to severe NK who had undergone neurosurgery for acoustic neuroma, trigeminal neuralgia, or neoplasm were recruited from the Neurosurgery Department of a tertiary hospital. All operations were finished by the same set of experienced doctors. The unaffected contralateral eyes of the patients with NK and 20 eyes from normal subjects were analysed as controls. Patients with NK caused by diabetes, herpes virus, the wearing of contact lenses, eye surgery, or other types of keratitis were excluded. This study was approved by the Ethics Committee Review Board of Tianjin Medical University Eye Hospital and adhered to the tenets of the Declaration of Helsinki. Written informed consent was obtained from all patients.
