title: Inflow of ocular surface fluid into the anterior chamber after phacoemulsification through sutureless corneal cataract wounds.
abstract: OBJECTIVE
  To report inflow of extraocular fluid after phacoemulsification with use of sutureless corneal incisions.
  
  
  METHODS
  Interventional case series.
  
  
  METHODS
  setting: Wilmer Eye Institute, Johns Hopkins Hospital, Baltimore, Maryland. patients: Eight patients (three women), aged 58 to 91 years, showing minimal bleeding from the limbal capillary bed during phacoemulsification. intervention: Surgery was performed through a 2.8-mm limbal incision. External pressure simulating patient manipulation was applied before and after wound hydrosealing with an irrigation cannula. main outcome measures: Inflow of blood-tinged tear fluid into the anterior chamber through the wound was monitored by using digital video.
  
  
  RESULTS
  Inflow of extraocular fluid was observed in all eyes when the cannula was released, even after wound hydrosealing. Two patients showed spontaneous fluid inflow.
  
  
  CONCLUSIONS
  Tested sutureless corneal incisions allow inflow of extraocular fluid into the anterior chamber after phacoemulsification. This may permit intraocular contamination leading to endophthalmitis.
