The authors analyzed three full-thickness corneal buttons and two corneal scleral rims obtained 5 1/2 to 44 months after three trapezoidal keratotomies (Ruiz), one "L," and one "TL" procedure. The indications for the penetrating keratoplasty were photophobia, corneal edema, and loss of best-corrected vision after the astigmatic keratotomy procedures. Epithelial plugs were seen in all five specimens. Complete basal lamina lined the wounds in two cases. Tangential incisions of the Ruiz procedure were shallower and demonstrated more advanced wound healing than the corresponding semiradial incisions. Two of the three Ruiz procedures demonstrated peripheral separation of the semiradial incisions. Wound healing events after astigmatic keratotomy procedures appear similar to those reported previously after standard radial keratotomy with the exception that tangential incisions appear to heal faster than the semiradial incisions.
作者分析了3个全层角膜纽扣和2个角膜巩膜缘组织块，这些组织是在3次梯形角膜切开术（鲁伊斯术式）、1次“L”形手术和1次“TL”形手术后5个半月至44个月获取的。穿透性角膜移植术的指征为畏光、角膜水肿以及散光性角膜切开术后最佳矫正视力丧失。在所有5个标本中均可见上皮栓。2例标本的伤口处有完整的基底膜。鲁伊斯术式的切线切口较浅，与相应的半放射状切口相比，显示出更高级的伤口愈合。3例鲁伊斯手术中有2例显示半放射状切口出现周边分离。散光性角膜切开术后的伤口愈合情况与之前报道的标准放射状角膜切开术后的情况相似，不同之处在于切线切口似乎比半放射状切口愈合得更快。
