    Author: Lebuisson DA, Lim P, Mary JC, Jolivet MC.
    Journal: J Fr Ophtalmol; 1996; 19(3):181-9. PubMed ID: 8731767.
    Abstract:
    PURPOSE: This prospective study compares the analgesia obtained by topical anaesthesia versus a single peribulbar anaesthesia. The comparison is made during clearcornear phacoemulsification in adult patient. METHODS: Ninety-six eyes are operated with Lidocaine 2% (66) or Tetracaine 1% (30) topical anaesthesia, 38 eyes received an unique anterior periocular injection. The same surgeon performs the phacoemulsification in 2 different centers. Analgesia is evaluated in the per and post operative period by the surgeon and a nurse. RESULTS: Four cases (4.2%) in the topical anaesthesia group required a complementary subconjonctival anaesthetic injection. Seven cases (7.3%) had pain during surgery but without any need for a complementary injection. In the other group 1 injection was necessary (2.5%). A slight pain was felt by 5% of patients during surgery. CONCLUSION: Topical anaesthesia is reliable but needs a patients selection, a well trained staff and a non beginner surgeon. The advantages are obvious for out patient surgery if no premedication is associated. Many doctors will continue to ask for an akinesia during cataract surgery even is the analgesia is obtained.
