The "sublingual troche" Dr. Berdahl uses generally is given in one-, one-and-a-half or two-tablet dosages. He estimates 40% of his cataract patients get one tablet, 30% get one and a half and the other 30% get two tablets before surgery. The dosage is driven primarily by age. "The older the patient, the less sedation they receive," says Dr. Berdahl. The final and, according to Dr. Berdahl, potentially greatest big-pic- ture benefit of oral sedation options is that they're opioid-free. "The ability to avoid fentanyl in cataract procedures is important," says Dr. Berdahl. "The literature shows patients who receive opioids only once can face problems of dependency."
