title: Topical anesthesia for transpupillary silicone oil removal combined with cataract surgery.
abstract: OBJECTIVE
  To assess safety of topical anesthesia for transpupillary silicone oil removal in combination with cataract surgery.
  
  
  METHODS
  Department of Ophthalmology Mannheim, University of Heidelberg, Mannheim, Germany.
  
  
  METHODS
  The clinical interventional study included 37 consecutive patients having transpupillary silicone oil removal combined with cataract surgery. Without exception, surgery was carried out in topical anesthesia for all patients. During the study period, there were no patients having transpupillary silicone oil removal in another type of local anesthesia than topical anesthesia. Topical anesthesia was achieved with oxybuprocaine 0.4% eyedrops installed 4 to 5 times prior to surgery. Cataract surgery was performed using the clear cornea technique with implantation of a foldable intraocular posterior chamber lens. Silicone oil was released through a planned posterior capsulotomy during cataract surgery prior to implantation of the intraocular lens (IOL).
  
  
  RESULTS
  For all patients, surgery could be carried out in topical anesthesia without switching to peribulbar or any other type of anesthesia. None of the patients complained about severe pain intraoperatively or postoperatively. No severe complications such as expulsive hemorrhage, luxation of the IOL, or iris incarceration were encountered in any of the surgeries.
  
  
  CONCLUSIONS
  Transpupillary silicone oil through a planned posterior capsulotomy during cataract surgery may be performed in topical surgery.
