title: [A long-term evaluation for opticfull-thickness lamellar keratoplasty].
abstract: OBJECTIVE
  To investigate the long-term optic effects of optic full thickness lamellar keratoplasty (OFLK) and penetrating keratoplasty (PKP) and compare their effects.
  
  
  METHODS
  44 cases (48 eyes) with stromal disorder with normal endothelial function were treated by OFLK (25 eyes) or PKP (23 eyes). The optic effect of OFLK group was compared with that of the PKP group, and the endothelial density in partial cases was observed.
  
  
  RESULTS
  The rate of transparent graft of OFLK group was 84.0%, and that of PKP group was 69.6% at postoperative 2 - 3 years, the rate of escaping blindness being 80% and 78.3% respectively. The rate of obtaining more than 0.3 vision in OFLK group was 40.0%, and in PKP group was 21.7%. Postoperatively, the endothelial cell density tended to decrease with time in PKP group, but was relatively stable in OFLK group.
  
  
  CONCLUSIONS
  The results show that the optic effect of OFLK group is similar to that of PKP group, and the safety, less complications of OFLK group are the same as that of lamellar keratoplasty. It is considered that OFLK might have a bright future and the operative technique should be further studied.
