PurposeTo describe a method of deep sedation without adjunctive periocular injection in phacoemulsification with a scleral tunnel technique.MethodsAll patients undergoing phacoemulsification with a scleral tunnel and foldable intraocular lens for cataract between May 2011 and November 2014 received deep sedation including a bolus of midazolam and fentanyl followed by a continuous perfusion of dexmedetomidine throughout the surgical procedure. The patients and medical team evaluated pain, sedation, clinical status of the patient, and surgeon comfort.ResultsOne thousand and five hundred patients were included, representing 1763 eyes. Ramsay's sedation score was 2 in 7.13% of cases and 3 in 86.3%, which allowed surgery to be performed under very satisfactory conditions. On a scale of 1 to 10, intraoperative pain was less than or equal to 1 in 81.2% of cases. The bradycardic and hypotensive effects of dexmedetomidine were appreciable, while respiratory depression was not observed. Only 1 case of severe agitation during surgery directly resulted in a vitreous issue. Some simple precautions allow optimization of the advantages of this method of anesthesia.ConclusionThe deep sedation method including bolus injections of midazolam and fentanyl and continuous perfusion of dexmedetomidine affords a certain comfort to the patient as well as the surgeon in phacoemulsification of cataract through a scleral tunnel without adjunctive periocular injection.Copyright © 2015 Elsevier Masson SAS.
