Evaluation of Effectiveness and Safety of Lidocaine Gel as Anesthetic Agant in Phaco Cataract Surgery with Corneal Incision

Backgroud and objectives: With surprising advances in cataract surgery techniques, reviewing and try to making better the anesthetic procedures is obviously mandatory.To evaluate safety and efficacy of lidocain gel in cataract surgery by phacoemulsification with corneal incision is in this background and have been done for this aim. Setting: Nikookari Eye Center, TUMS, Tabriz, Iran. Materials and method: We operated 25 cataract patients with lidocaine 2%gel as topical anesthetic agent in phacoemulcification, and foldable lens implantation procedure with corneal incision.23 other patients who had the same conditions, operated with traditional retrobulbar injection anesthesia. Sedation by intravenous midazolam also used in magority of the cases. Patients asked for pain and satisfaction at the end of procedure,and recorded in a questionare. Surgeon’s satisfaction and intra and/or postoperative complications also included in the same sheet. Results: All but one of the patients in the gel group tolerated the procedure well, and satisfied well. Pain score was sever in 1, moderate in 18, and weak in 6 cases in gel group, but all the retrobulbar group had sever pain at the time of injection, (p < 001).The differenc between patient’s and surgeon’s satisfaction was also statisticaly meaningful, (p < 001). We had one case opening of posterior capsule in each group, and there was no post operative complication other than mild and transient corneal edema that resolved soon, and it was not apparent in second visit one week later. Conclusion: 2% Lidocaine gel can be used as an effective and safe anesthetic agent in phaco cataract surgery with corneal incision.
