To evaluate the efficacy of automated lamellar therapeutic keratoplasty (ALTK) in the treatment of anterior to mid-stromal corneal pathologies.
A prospective clinical study was undertaken in 15 eyes of 15 patients who underwent ALTK using the ALTK System (Moria/Microtek Inc., Doylestown, Pennsylvania, USA). The parameters evaluated were uncorrected and best corrected visual acuity (BCVA), keratometry, pachymetry, contrast sensitivity, glare acuity, intraoperative surgical time and complications, postoperative time to epithelialization, graft clarity and postoperative complications.
The mean surgical time was 46 +/- 9 mins. The BCVA, contrast sensitivity and glare acuity significantly improved at 6 months postoperatively. The mean decimal BCVA was 0.08 +/- 0.03 preoperatively, which improved to 0.33 +/- 0.30 at 6 months, when 11 eyes had BCVA > or = 6/18. The median epithelialization time was 3 days (range 1-10 days).
Automated lamellar therapeutic keratoplasty appears to be safe and effective for diseases affecting the anterior to mid-stroma of the cornea.
评估自动板层治疗性角膜移植术(ALTK)治疗角膜前基质至中基质病变的疗效。
对15例患者的15只眼进行前瞻性临床研究,这些患者使用ALTK系统(美国宾夕法尼亚州多伊尔斯顿的Moria/Microtek公司)接受了ALTK治疗。评估的参数包括未矫正和最佳矫正视力(BCVA)、角膜曲率测量、角膜厚度测量、对比敏感度、眩光视力、术中手术时间及并发症、术后上皮化时间、植片清晰度和术后并发症。
平均手术时间为46±9分钟。术后6个月时,BCVA、对比敏感度和眩光视力显著改善。术前平均小数视力BCVA为0.08±0.03,6个月时提高到0.33±0.30,此时11只眼的BCVA≥6/18。上皮化时间中位数为3天(范围1 - 10天)。
自动板层治疗性角膜移植术对于影响角膜前基质至中基质的疾病似乎是安全有效的。
