title: [Immediately sequential bilateral cataract surgery in dogs: a retrospective analysis of 128 cases (256 eyes)].
abstract: OBJECTIVE
  To describe postoperative complications and visual outcomes after immediately sequential bilateral cataract surgery (ISBCS) and to assess whether additional risk is incurred by operating on the fellow eye immediately following the first.
  
  
  METHODS
  A retrospective review of 128 dogs (256 eyes) that underwent ISBCS in three veterinary ophthalmology centers between May 2007 and December 2011 was performed.
  
  
  METHODS
  Visual status at final evaluation was recorded and intra- and postoperative complications were recorded and analyzed. Data for the first operated eye (FE) and then the second eye (SE) were statistically analyzed to assess whether performing surgery on the SE immediately after the FE resulted in any negative consequences for the second eye.
  
  
  RESULTS
  No serious intraoperative anesthetic incident occurred due to prolonged surgery. Phacoemulsification times were significantly shorter for the SE than for the FE. On final examination, 239 eyes out of 256 (93.36%) exhibited functional vision (score 2), and three dogs were completely blind due to long-term bilateral postoperative complications. The most common postoperative complications were uveitis (58 eyes, 22.66%), postoperative ocular hypertension (POH; nine eyes, 3.5%), glaucoma (nine eyes, 3.5%) and total retinal detachment (seven eyes, 2.73%). No case of endophthalmitis was reported. These results were no worse than those typically reported for unilateral phacoemulsification. In addition, the risk of blindness and other postoperative complications was not significantly increased in the SE.
  
  
  CONCLUSIONS
  The results of this study suggest that ISBCS is not associated with an increased incidence of intra- or postoperative complications compared to classic unilateral cataract surgery and might be a viable option for selected patients. The risk of blindness or postoperative complications was not higher in SEs than in FEs.
