The data was analyzed using professional statistical methods.Results: There were 28 patients included in this study, including 16 males and 12 females, with an age range of 21-73 years. The corneal thickness, corneal endothelial cell density, corneal curvature and corneal astigmatism at 1 month, 3 months, 6 months and 1 year after surgery were significantly different from preoperative values (P<0.05). Patients' postoperative visual acuity improved significantly, with mean 精品文档---下载后可任意编辑visual acuity of 0.5, 0.6, 0.7 and 0.8 at 1 month, 3 months, 6 months and 1 year after surgery, respectively (P<0.05).Conclusion: Secondary penetrating keratoplasty can significantly improve corneal parameters and visual acuity. It is a feasible treatment option for patients with corneal disease.Keywords: keratoplasty, penetrating, secondary, corneal parameters, visual acuity recovery
