Abstract

Purpose: To evaluate the efficacy of topical anesthesia; topical Benoxinate 0.4% (Oxybuprocaine) and Xylocaine (Lidocaine) gel, in selected cataract patients as an alternative to peribulbar or retrobulbar block anesthesia during cataract surgery.

Materials and methods: Prospective non-comparative evaluation of patients' and surgeon's satisfaction at the end of the procedure. Three hundred patients (300 eyes) were included in the study. The procedure was explained to patients with details regarding what will happen and what to expect during surgery. All patients received topical anesthesia with Benoxinate 0.4% eye drops and Xylocaine gel 2%. All surgeries were done by the same surgeon using the same machine (updated LEGACY phacoemulsifier, Alcon) and approach (clear corneal incision) and followed by a foldable intraocular lens (IOL) implantation.

Results: None of the patients had severe pain during the procedure; only 2% (six of 300) required use of intravenous sedation (Propofol), both the surgeon's and the patients' satisfaction were high. Eye movements and blepharospasm were not significant problems, and no serious complications occurred. Rate of vitreous loss due to posterior capsule tear/rupture was within literature reported range and not different from our previous experience.

Conclusion: Topical anesthesia is a satisfactory and safe alternative to retrobulbar and peribulbar anesthesia for clear corneal phacoemulsification and intraocular lens implantation in selected cataract patients in the hands of experienced cataract surgeon.

Keywords: Clear cornea phacoemulsification; patient and surgeon satisfaction; sedation; topical anesthesia.
