目的探讨深板层角膜移植治疗圆锥角膜的价值。方法采用深板层全厚角膜供体植片治疗圆锥角膜22例(25眼),对其疗效进行观察、分析。结果术后平均随访5-26个月,术后裸眼视力≥0.2者20例(23眼)矫正视力≥0.4者17例(19眼),矫正视力≥0.7者3例(4眼),发生排斥反应3例(4眼),植片透明20例(23眼),植片半透明2例(2眼)。结论深板层角膜移植治疗圆锥角膜具有对材料要求条件低,不涉及前房及排斥反应低,治疗效果好等优点,在临床上值得推广应用。
Objective To investigate the value of deep lamellar keratoplasty in the treatment of keratoconus. Methods 22 cases (25 eyes) of keratoconus were treated with deep layer full-thickness corneal donor grafts. The curative effect was observed and analyzed. Results The mean postoperative follow-up was 5-26 months. There were 17 cases (19 eyes) corrected visual acuity ≥ 0.4 in 20 cases (23 eyes) and 3 cases (4 eyes) corrected visual acuity ≥ 0.7 in the patients with uncorrected visual acuity ≥0.2. There were 3 cases (4 eyes), 20 transparent cases (23 eyes) and 2 translucent cases (2 eyes). Conclusion Deep lamellar keratoplasty has the advantages of low material requirements, low anterior chamber and low rejection, and good curative effect. It is worthy of clinical application.
