From cocaine topical anesthesia, immobilized patients, and extracapsular technique on ‘ripe’ cataracts we advanced to retrobulbars, sutured incisions, and intracapsular technique. Today’s techniques recapitulate those of old, with topical anesthesia and intact capsular bag support of implants enabling virtually instant visual recovery, m...

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...

PURPOSE To present a case series on the use of dexmedetomidine (Precedex) sedation in painful posterior segment surgery performed under topical anesthesia, similar to its use in cataract surgery. METHODS A prospective review of cases that had posterior segment surgery under topical anesthesia and that needed sedation. Dexmedetomidine-loading infusion was 1 mcg/kg over 10 minutes, followed by ...
