摘　　要：目的探讨在施行偏中央的治疗性穿透性角膜移植术时，恢复视力和减少角膜散光的有效方法。方法标记植孔中央所在的子午线及在该子午线上植孔外缘与角膜缘的距离（两点标记法）；在供眼取相同位置的植片，按标记移植和缝合，对２３例偏中央的角膜溃疡穿孔患者施行偏中央的治疗性穿透性角膜移植术，术后随访３个月至２年。结果１８例移植片透明，１６例裸眼视力０．１以上，６例０．４以上，２例达１．０。结论采用两点标记法施行偏中央的治疗性穿透性角膜移植术，能有效地减少角膜散光，且获较佳视力。此法简单，易于掌握。Objective To study the effective ways to restore sight and control the postoperative corneal astigmatism in eccentric penetrating keratoplasty. Methods Marks were made on the meridian where the center of recipient bed was located, and at that meridian the distance between the external edge of recipient bed and the limbus (two point marking technique) was also marked. Afterward, the donor graft was cut down from a donor eye at the corresponding position and sutured on the recipient bed. This technique was performed on 23 cases with eccentric corneal ulcer and perforation, and they were followed up for 3 months to 2 years. Results The grafts of 18 eyes remained transparent. The visual acuities were obtained > 0.1 in 16 cases, > 0.4 in 6 cases. Among them, visual acuity of 1.0 was obtained in 2 cases. Conclusions Two point marking technique can reduce the postoperative corneal astigmatism and obtain satisfactory visual acuity in eccentric penetrating keratoplasty. This technique is simple and easy to perform.
