摘要
目的观察应用飞秒激光技术辅助行穿透性角膜移植手术（FS．PKP）的初步临床疗效。方法回顾性病例研究。分析6例（6眼）行FS—PKP术的患者，术前视力从手动到0．05不等，病变均累及角膜全层。根据病变性质及范围不同，利用飞秒激光制作不同形状的植片和植床，2例患者行Zig—Zag（之字形）切割，1例行Zig-Square（上方之字形，下方方形）切割，1例行蘑菇形切割，2例行礼帽型切割。术后均按常规穿透性角膜移植术进行治疗。结果随访期间，视力均较术前有不同程度提高，视力达0．5及以上者3例．其中1例患者视力恢复至1．0。术后1年时6例患者散光值在2．25～5．00D之间。1例Zig．Zag型切割患者术中发生偏中心切割，术后10个月完全拆线后行飞秒激光散光矫正术；1例礼帽型切割角膜移植患者术后早期出现高眼压。余患者未见明显并发症。结论应用FS-PKP术治疗角膜病变，可操作性强，切削精确，瘢痕轻，术后散光小。
Objective To report the clinical results of femtosecond laser assisted penetrating keratoplasty （FS-PKP）. Methods It was a retrospective case series study. Six eyes of 6 patients who treated with FS-PKP were enrolled in this study. The vision of them were from hand moving to 0.05, and opacities were all from epithelium to endothelium. During the operation, the grafts were prepared to different shapes according to the character of the affections： 2 cases with Zig-Zag shape, 1 case with Zig-Square, 1 case with mushroom, and another 2 cases with hat shape. Results During the follow-up period, the visions of all patients were better than preoperative ones. Three of them were better or equal to 0.5, and one was even to 1.0. The astigmatisms were from 2.25 D to 5.00 D at one year after operation. During the operation of one case with Zig-Zag shape, the meta-central cut were happened. Another patient with hat shape experienced high intraocular pressure early after operation. Conclusion The FS-PKP appears to be a good alternative surgical method for patients of corneal diseases because of the great manipnility and excellent postoperative results.
