title: [Results of surgery on white cataract using trypan blue capsule staining to visualize capsulorrhexis].
abstract: OBJECTIVE
  To evaluate surgery on white cataracts using trypan blue capsule staining.
  
  
  METHODS
  A retrospective study comprised 64 eyes of 60 patients with white cataract that had surgery with trypan blue capsule staining. The average age was 62.4 years and progress observation periods were 5.6 months. The rate of successful continuous curvilinear capsulorrhexis(CCC), complications, visual acuity, intraocular pressure(IOP), flare value, and corneal endothelial cell loss were studied.
  
  
  RESULTS
  The CCC was completed uneventfully in 93.8% eyes. Posterior capsule rupture occurred in 2 eyes, and early perforation in 1 eye. Accidental vitreous staining and endothelial staining with trypan blue were observed in 1 eye each. There were no postoperative complications associated with trypan blue. Forty-five eyes had a best corrected visual acuity of 0.8 or better at the last visit. Twelve eyes had some ocular pathology resulting in visual loss, and a reliable visual acuity test could not be performed in 6 eyes. The mean postoperative IOP was within the normal range. The mean postoperative flare returned to within normal range 1 month after surgery. The mean corneal endothelial loss was 13.7%, and that of eyes with nucleus of grade 2 or softer was only 2.9%.
  
  
  CONCLUSIONS
  Cataract surgery using trypan blue was safe and effective in managing white cataracts.
