Conscious Sedation Efficacy of the MKO Melt (Midazolam, Ketamine, Ondansetron)

Conscious Sedation Efficacy of the Novel Medication, MKO Melt (Midazolam, Ketamine, Ondansetron), During Cataract Surgery

The investigators hypothesized that the combination of Valium, Tramadol and Zofran is superior to the substantially more expensive MKO melt in patient satisfaction after cataract surgery.

The MKO melt is being marketed as an anesthetic medication for cataract surgery that has the advantage that it eliminates the need for an IV in 85% of patients although that number was established anecdotally. This alternative, however, is very cost limiting.The investigators wanted to see if the current regimen (valium only) or a combination similar to the MKO melt (valium + tramadol + zofran) are as good if not better than the MKO melt for anesthesia and how many patients could have indeed gone with an intravenous line (didn't need any extra medications).
