title: [Capsular rupture in cataract operations with sponge surface and intra-anterior chamber anesthesia].
abstract: BACKGROUND
  Combined topical and intracameral anaesthesia has become increasingly popular in cataract surgery. The purpose of this study was to determine the risk of capsular lesions with an intact motility during surgery.
  
  
  METHODS
  In a prospective clinical study, we analyzed 2000 phacoemulsifications with IOL implantation performed by an experienced surgeon with combined sponge and intracameral lidocain anaesthesia. Preoperatively two grades of difficulty of the surgical procedure were defined.
  
  
  RESULTS
  Operations were carried out on 1,658 patients with a (grade 1) low degree and 342 patients (grade 2) with a high degree of difficulty (17.1%). Capsular lesions occurred in 17 operations (0.85%), 15 in cases with a high degree of difficulty (88%). In 12 of these, an anterior vitrectomy was necessary and in 1 operation a pars plana vitrectomy after application of additional retrobulbar anaesthesia was performed.
  
  
  CONCLUSIONS
  In this study the incidence of capsular lesions was not increased compared to other methods of anaesthesia. Anterior vitrectomy with the patient under combined sponge and intracameral anaesthesia, was possible without retrobulbar anaesthesia.
