"Edge Pharmacy Services worked with us in developing our block mixture over 2 years ago. Since that time we have performed over 20,000 blocks at various sites in New York and New England. The performance of the blocks has been outstanding. We receive our blocks in a timely and secure manner. Given the recent environment surrounding the compounding of medications and the challenges providers face, Edge Pharmacy Services has allowed us to continue to provide our patients and centers with the quality and safety they deserve."

"The improved efficacy of retrobulbar block by the addition of hyaluronidase to the local anesthetics was clearly demonstrated by the trial."
"Originally the authors were skeptical that any difference at all would be demonstrated, and a far larger trial had been contemplated. However, on completion of this number  it was clear that to continue to perform retrobulbar block without the addition of hyaluronidase would be unjustified."

"Each time a needle is introduced into the orbit, there is a small but definite risk of complication. Successful block from a single injection is therefore desirable. Our study has shown that this is most likely to be achieved when hyaluronidase is added to the solution."

"The addition of hyaluronidase significantly improved the success of the motor block."
"Supplementary blocks were needed significantly more often when the local anesthetic solution was hyaluronidase-free."
