To determine the safety and efficacy of intracameral injections of unpreserved lidocaine to reduce intraocular sensation.
Carolina Eye Associates, Southern Pines, North Carolina, USA.
In this prospective study, 100 patients having phacoemulsification under topical anesthesia were randomly assigned to receive an intracameral injection of unpreserved lidocaine (0.5 cc of a 1% unpreserved solution) or balanced salt solution.
Ninety-three patients completed the study. There were no significant between-group differences in cell density parameters or Kowa laser flare-cell meter measurements. Seventy-eight percent of lidocaine patients and 56% of controls reported no sensation (P = .048, Fisher's exact test).
Intracameral injections of unpreserved lidocaine safely and effectively reduced intraocular sensation during phacoemulsification.
