为观察板层角膜移植治疗翼状胬肉及角膜皮样瘤的疗效,我们对17例(17只眼)翼状胬肉患者及5例(5只眼)角膜皮样瘤患者进行了板层角膜移植。术后随访1～4年。翼状胬肉组和角膜皮样瘤组植片透明率分别为82.4%及100%。翼状胬肉组排斥反应发生率为17.6%,角膜皮样瘤组无一例发生排斥反应。所有病例角膜中央厚度手术前后差异无显著性意义(P>0.05)。两组病例术后角膜散光均较术前降低,差异均有显著性意义(P<0.05)。两组病例术后视力均有不同程度提高。翼状胬肉组术后复发率为11.8%。结果表明板层角膜移植可使角膜完整、植片透明、减少散光、提高视力并降低术后翼状胬肉的复发率,是一种理想的治疗方法,值得推广。
To observe the efficacy of lamellar keratoplasty in the treatment of pterygium and corneal dermoid tumors, we performed lamellar keratoplasty on 17 patients (17 eyes) with pterygium and 5 patients (5 eyes) . Follow-up 1 to 4 years after surgery. The transparence rates of the pterygium group and the corneal dermoid tumor group were 82.4% and 100% respectively. The incidence of rejection in the pterygium group was 17.6%. No rejection occurred in the corneal dermoid tumor group. There was no significant difference in central corneal thickness between before and after surgery (P> 0.05). Corneal astigmatism in both groups was lower than that before operation, the differences were significant (P <0.05). Visual acuity in both groups increased to varying degrees. Pterygium recurrence rate was 11.8%. The results show that lamellar keratoplasty can corneal integrity, transparency of the graft, reduce astigmatism, improve visual acuity and reduce the recurrence rate of pterygium after surgery, is an ideal method of treatment, it is worth promoting.
