That is the therapeutic keratoplasty, the treatment of the primary disease or the preservation of the ultimate goal of the eye, but also to obtain vision.

Partially penetrating keratoplasty visual acuity can be corrected, when the correction and postoperative refractive changes and other issues, are doctors and patients are concerned. At present, there are no reports of refractive changes after partial penetrating keratoplasty in our country. We conducted regular follow-up of the cases after the penetrating keratoplasty. The changes of refractive changes of the 55 patients who were followed up for 3 years with complete data were summarized The report is as follows: Clinical data 55 patients (all monocular surgery), 43 males and 12 females, the youngest 8 years old, the largest 55 years old, 20 ~
