Comparison of Lidocaine Gel–Assisted Transconjunctival and Transcutaneous Local Anesthesia for Outpatient Eyelid Surgery

Abstract

Transconjunctival local anesthesia in conjunction with topical anesthesia with 2% lidocaine gel provides a clinically and statistically significant decrease in perceived pain when compared with transcutaneous anesthesia in patients undergoing outpatient eyelid surgery.

The Effectiveness of 2% Lidocaine Gel Compared to 0.5% Tetracaine Eye Drop As Topical Anesthetic Agent for Phacoemulsification Surgery

“…However, the absorption and duration of this agent is slower in comparison with gel preparation. Therefore, the 0.5% tetracaine eye drop must be administered repeatedly with the risk of corneal epithelial damage due to its toxic reactions, including punctate keratopathy, persistent epithelial defect, ring shaped stromal infiltration, corneal edema, Descemet’s membrane filding, endothelial cell loss to neurotrophic ulcer, stromal melting, secondary infectious keratitis, corneal scarring, and corneal perforation (2, 3). …”
