Eye surgeons who routinely use injection anesthesia may find it helpful to utilize a device to shield the globe and periocular structures.
The Retrobulbar Guide (Rhein Medical) was developed for such a purpose.
I have found these injections to be very well tolerated with the addition of a preparatory skin wheal and mild intravenous sedation. With the latter, it is rare for a patient even to remember the injection at all. Occasionally, a very small orbit requires a peribulbar placement. Complications have been extremely rare.
I would recommend this instrument to anyone looking for an easier and safer way to perform retrobulbar or peribulbar injections. This instrument also can be used with a blunted retrobulbar needle for additional safety, if desired.
