The results of two year follow-up after Holmium LTK are presented. The choice of the technique was justified based on experimental, technical and anatomo-pathological data as well as on the property of the corneal collagen fibers to shrink at a temperature of 60-70 degrees C. Although the immediate results were encouraging, we found an important regression after two years follow-up, resulting in a final correction of maximally 1.5 D, independent on the degree of hypermetropia to be treated. These results were obtained with the "contact" method, which is in our experience slightly superior to the "non-contact" technique. The question is whether the regression will continue with time or will stabilize and remain at 1.5 D of hyperopic correction.
本文展示了钬激光热角膜成形术（Holmium LTK）两年随访的结果。基于实验、技术、解剖病理学数据以及角膜胶原纤维在60 - 70摄氏度会收缩的特性，该技术的选择是合理的。尽管即时效果令人鼓舞，但我们发现在两年随访后有显著回退，最终最大矫正量为1.5 D，与待治疗的远视度数无关。这些结果是通过“接触”法获得的，根据我们的经验，该方法略优于“非接触”技术。问题在于这种回退是否会随时间持续，还是会稳定下来并维持在1.5 D的远视矫正量。
