| Objective To evaluate the epidemiologic characteristics of patients who receivedpenetrating keratoplasty (PKP) in our hospital from Jan.2005 to Dec.2006, and study themain causes, effects and complications of penetrating keratoplasty.Methods Retrospective analysis of 49 cases of penetrating keratoplasty.ResultsCauses: infectious keratitis 33 cases(67.35%), ocular trauma and correlative cornealleucoma 6 cases(12.24%), primary corneal endothelial decompensation after the firstpenetrating keratoplasty with chilled corneas 3 cases(6.12%), grafts rejection 2 cases(4.08%),degeneration and dystrophy 2 cases(4.08%), bullous keratopathy 1 cases(2.04%),keratoconus 1 cases(2.04%), iridocorneal endothelial syndrome 1 cases(2.04%).Effects: grafts are transparent in 41 eyes(83.67%), turbid in 8 eyes(16.32%). Visual acuity:hand move 2 cases(4.08%), finger count 6 cases (12.24%), 0.1~0.3 23 cases(46.94%),0.4~0.8 18 cases(36.73%).Complications: immune rejection 19 cases(38.78%), shallow anterior chamber 3cases(6.12%), secondary glaucoma 1 cases(2.04%).Conclusion penetrating keratoplasty is an effective means for disorders of cornea.Prevention and treatment of immune rejections are the key to the success of operations. |
