title: Postoperative inflammatory response to phacoemulsification and extracapsular cataract surgery: aqueous flare and cells.
abstract: OBJECTIVE
  To compare the postoperative blood-aqueous barrier (BAB) breakdown induced by phacoemulsification with continuous curvilinear capsulorhexis (CCC) and by extracapsular cataract extraction (ECCE) with a linear capsulotomy.
  
  
  METHODS
  Cataract and Refractive Surgery Research Unit, Department of Ophthalmology, St. Thomas' Hospital, London, United Kingdom.
  
  
  METHODS
  Anterior chamber flare and cells were measured preoperatively and 1 day, 1 week, and 1 and 3 months postoperatively in two parallel groups of 31 consecutive cataractous eyes. In Group 1, one surgeon performed ECCE with a linear capsulotomy; in Group 2, a second surgeon performed divide and conquer phacoemulsification with CCC. The preoperative, intraoperative, and postoperative medication regimen was the same in both groups.
  
  
  RESULTS
  Group 2 eyes had significantly lower anterior chamber flare and cell measurements in the first postoperative month than Group 1 eyes (.01 < P < .00001).
  
  
  CONCLUSIONS
  Phacoemulsification with CCC induced a less severe BAB breakdown than ECCE with a linear capsulotomy. Phacoemulsification with CCC may be preferable in high-risk eyes such as those with glaucoma, diabetes, or uveitis, which are prone to complications resulting from postoperative BAB breakdown.
