title: [Preliminary clinical study of Descemet's stripping with endothelial keratoplasty for bullous keratopathy].
abstract: OBJECTIVE
  To investigate the indications, surgical procedure, clinical efficacy, and the prevention and management of complications of Descemet's stripping with endothelial keratoplasty (DSEK) for bullous keratopathy.
  
  
  METHODS
  In the nonrandomized retrospective consecutive case series, 8 patients (8 eyes) with bullous keratopathy at Zhongshan Ophthalmic Center between September 2006 and October 2007 underwent DSEK surgery. During the surgical procedure, the Descemet's membrane and abnormal endothelial layer were stripped from the central recipient posterior surface with 7.75 mm diameter, and then a specially designed scraper was used to roughen the peripheral recipient posterior stroma. Other surgical techniques were the same with routine DSEK surgery. The adherence of the donor lenticule to the recipient posterior stroma and postoperative donor lenticule dislocation were monitored in the early stage after surgery. Best spectacle-corrected visual acuity (BSCVA), graft clearance, corneal astigmatism and endothelial cell density (ECD) were observed over a 3-9 months follow-up period.
  
  
  RESULTS
  All donor lenticules were well adherent to the recipient posterior stroma and no graft dislocation occurred postoperatively. One patient had papillary block glaucoma at 1-day, and relieved after 48 hours postoperative. All grafts remained transparent, and had improved visual acuity. BSCVA was 0.3 - 0.7 postoperative. Six patients with preoperative pain had been pain free after DSEK procedure. Mean corneal astigmatism was (1.90 +/- 0.70) diopter (D). Mean ECD was (2014 +/- 192) cells/mm(2).
  
  
  CONCLUSIONS
  Compared with deep lamellar endothelial keratoplasty (DLEK), DSEK procedure is technically easier and less traumatic to recipient cornea and anterior chamber structures. The skill of roughening the peripheral recipient posterior stroma should prevent postoperative graft dislocation effectively.
