The Contrastive Study Of Deep Lamellar Keratoplasty And Penetrating Keratoplasty In Treating Keratoconus

ObjectiveTo observe the changes of visual acuity, keratometry values and corneal endothelial cells after deep lamellar keratoplasty or penetrating keratoplasty in keratoconus.MethodsTo divide the keratoconus patients who accepted operations from January 2003 to December 2004 into two groups: one group accepted deep lamellar keratoplasty (n=9), the other one accepted penetrating keratoplasy (n=9). Postoperative uncorrected visual acuity,best corrected visual acuity, corneal topography and corneal endothelial cells were observed.ResultsIn deep lamellar keratoplasty group, postoperatively the patients saw 4 lines more with no correction, 7 lines more with best correction and there was no rejection. In penetrating keratoplasty group, postoperatively the patients saw 5 lines more with no correction, 8 lines more with best correction and there were two patients had rejection. There were no difference in corneal cylinder and speed of decline of corneal endothelial cells after keratoplasty between the two groups.
