Today, many surgeries of the eye can be performed using techniques
that allow your ophthalmologist (Eye M.D.) to use just topical drops or injectable
anesthetics to completely numb your eye before your surgical procedure
rather than putting you to sleep using general anesthesia. If you are not an ideal candidate for topical anesthesia, peribulbar anesthesia is an excellent option.
Peribulbar anesthesia is the injection of a local
anesthetic around the eye that completely numbs the eye. First, your
ophthalmologist applies a topical anesthetic (eye drops) to numb the injection site between your eye and the lower lid. Then, the ophthalmologist introduces a needle to inject a local anesthetic. In some cases, a second
injection is required at another site. Your eye is completely numb, and
you feel no pain during surgery. The anesthetic also immobilizes your
eye so that your ophthalmologist can perform your surgery quickly and
easily.

By using peribulbar anesthesia, your ophthalmologist ensures that
you are as comfortable as possible during and following surgery. Since
you will not be put to sleep using general anesthesia, your recovery
time after surgery will be much quicker, and you will be able to go
home the same day.
Though very safe, there are some risks associated with peribulbar
anesthesia, as there are with most medical procedures. These risks are
due to the anesthetic, as well as to the injection procedure itself.
These risks include hemorrhage in the eye socket, perforation of the
eyeball, and damage to the optic nerve. Should you experience any
complications due to this procedure, it is possible that your doctor
will have to cancel and reschedule your surgery.
