【 摘 要 】

Purpose . Comparative analysis of long-term clinical and functional results of the intra-stromal MyoRing implantation according to standard techniques and optimized technologies using a femtosecond laser (FSL) in patients with keratoconus (KC), stages II and III. Material and methods . Results of surgical treatment of 60 patients (64 eyes) were analyzed in patients with KC of stages II and III. Depending on the technique of the operation, all patients were divided into  two groups. The group I consisted of patients with KC, who underwent the MyoRing implantation according to the standard technique, the group II used an optimized technology. The group I included  29 patients (32 eyes), the group II – 31 patients (32 eyes). In the group I the intra-stromal pocket of 9.0mm diameter was formed at a depth of 300 microns using the FSL. In the group II the intra-stromal pocket of 8.0mm diameter was formed at a depth of 80% of the minimum thickness of the cornea at the place of MyoRing location also using the FSL. The follow-up period averaged 36 months. Results.In the group I, in the period from 6 to 36 months postoperatively a regress was detected  in keratometric data, corneal thickness over the MyoRing and presence of posterior corneal elevation. In the  group II  all postoperative clinical and  functional parameters  achieved 12 months remained stable throughout the follow-up period. Both groups had no intra-operative complications. In group I, one case of the MyoRing protrusion was observed 24 months after surgery. Conclusion.   Application of the  optimized MyoRing  implantation technology compared to the standard one allows to improve more bio-mechanical parameters of the cornea and to reduce the risk of the ring protrusion.
