Abstract Purpose: To report 3 cases who were suspected of body movement and who received cataract surgery under intravenous infusion of dexmedetomidine(DEX).

Cases: A 65-year-old male showed marked anxiety. Cataract surgery was performed without body movement under use of DEX. Another 75-year-old female showed anxiety and senile dementia. She tried to get up after start of intravenous DEX. Cataract surgery could be performed without body movement thereafter. The other 41-year-old male had hypermature cataract, subluxation of the lens, and acute chamber angle closure. He showed ocular pain and anxiety. Cataract surgery was started under DEX but had to be switched to general anesthesia after body movement due to ocular pain.

Conclusion: Intravenous DEX infusion induced sedation during cataract surgery in patients with anxiety or senile dementia. Its use was limited in a case with ocular pain.
