Although difficult, recurrent forms of pterygium are seldom seen in central Europe, they cause considerable therapeutic problems because they cannot be cured by simple dissection and conjunctivoplasty. A useful method of treatment in these cases is the marginal, lamellar keratoplasty, which, according to the type of involvement, can take the shape of a sector, ring, horseshoe, or semicircle. If the pterygium is extensive and affects the center of the cornea, a subtotal, lamellar keratoplasty can be performed. The rate of recurrence in the group of 35 lamellar keratoplasties which we performed amounted to a satisfactory 31%. Only rarely did a pronounced astigmatism cause a decrease in the visual acuity postoperatively. Essential for the success of the procedures are exact surgical techniques and local use of atropine and cortison postoperatively. Just as with other surgical procedures, however, the lamellar keratoplasty cannot be considered the perfect method for all pterygiums.
虽然翼状胬肉的复发性形式在中欧很少见，但由于简单的切除术和结膜成形术无法治愈，它们会引发相当大的治疗难题。在这些病例中，一种有效的治疗方法是边缘板层角膜移植术，根据受累类型，其形状可以是扇形、环形、马蹄形或半圆形。如果翼状胬肉范围广泛并累及角膜中央，则可进行次全板层角膜移植术。我们实施的35例板层角膜移植术中，复发率令人满意，为31%。术后仅有极少数情况下，明显的散光会导致视力下降。手术成功的关键在于精确的手术技术以及术后局部使用阿托品和皮质类固醇。然而，与其他外科手术一样，板层角膜移植术不能被视为适用于所有翼状胬肉的完美方法。
