Abstract:
Objective:Through research of corneal transparency and related influential factors,the authors try to look for some clinical variety regulations after penetrating keratoplasty(PKP) in order to enhance the rate of surgery success.Methods:104 blind patients due to corneal disease (107 eyes) undergone PKP were followed up on months 1,3,6,12,18,24 and 36.Clarity of cornea,corneal endothelial cells and all kinds of complications were recorded besides regular examinations.Results:Grafts were transparent in 82 of 107 eyes on month 1(76.6%),in 69 of 90 eyes on months 6 (76.7%),in 51 of 81 eyes on months 12(63%),in 26 of 40 eyes on months 12 (65%) after PKP.Corrected vision were improved especially in patients of grafts transparency.Vision of patients with transparent grafts were more than 0.1 in 67 of 82 patients(82%) on month 1,in 59 of 63 patients(94%) on months 3,in 66 of 69 patients(96%) on months 6.Conclusion:PKP is an important method to corneal disease blind patients.Rejection was the major cause affecting graft transparency.
