Supports intramuscular dexmedetomidine 1.0 μg·kg⁻¹ for IOP reduction and sedation in day-case cataract surgery; extends RCT evidence for its perioperative ophthalmic use.
Does intramuscular dexmedetomidine reduce intra-ocular pressure and provide sedation in patients undergoing day-case cataract surgery?
Intramuscular dexmedetomidine at 1.0 micrograms.kg-1 effectively reduces intra-ocular pressure and provides moderate sedation with minimal hemodynamic side effects in outpatient cataract surgery.
