[Treatment of hypermetropia using the Holmium laser--laser thermokeratoplasty (LTK)].

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.
