Preoperative preparation should improve the likelihood of successful trabeculectomy surgery. The team can reconsider the appropriateness of the proposed surgery, and steps can be taken to maximize the chance of a good outcome. For example, adjustments to anti-hypertensive or anti-coagulant medications may be made, and topical ocular medications adjusted. Choice of anesthesia technique is of par...

Peribulbar anaesthesia has been recommended as a safer alternative to retrobulbar anaesthesia. We report a case of perforation of the globe sustained during peribulbar anaesthesia which resulted in blindness. Orbital injections are potentially dangerous, be they peribulbar or retrobulbar. To minimise the risk, short, blunt needles are advocated for the peribulbar route.

BACKGROUND To eliminate complications of peribulbar and retrobulbar anesthesia and to achieve efficacy and safety for topical anesthesia with cataract surgery. METHODS We performed clear corneal phacoemulsification with foldable intraocular lens (IOL) implantation under topical anesthesia using preservative-free 2% lidocaine drops, without intracameral anesthetic supplementation. The exclusio...

Hyaluronidase is an enzyme that has temporary and reversible enzymatic effects on the matrix of connective tissue. When added to local anesthetics in pain treatments, it enhances their infiltration and dispersal into tissues. It is widely used in anesthesia for ocular, dental, and plastic surgery. Reports of drug hypersensitivity to hyaluronidase are rare and are usually confined to peribulbar ...

PURPOSE The purpose of this study is to assess the efficacy and safety of intracameral mydriatic solution, as compared to preoperative topical mydriatics, in patients undergoing manual small incision cataract surgery (MSICS) under peribulbar anesthesia. To assess the sustainability of intracameral mydriasis in MSICS by monitoring pupil size at specific junctures during the surgery. METHODS Th...
