Abstract
BACKGROUND: The most popular method of keratorefractive surgery is sublamellar valve technology. It is known that excimer laser systems, which are widely used and are the gold standard in keratorefractive surgery, have a number of disadvantages. Alternative sources of UV radiation generation are solid-state laser systems, in particular the domestic Olimp 2000/213 laser, which previously had no experience in femto-assisted sublamellar surgery.
AIM: To evaluate clinical and functional results of correction of mild, moderate and high myopia using sublamellar keratomileusis technology, performed using the Schwind Amaris 1050 rs excimer laser and the Olimp 2000/213 solid-state ablative laser.
MATERIALS AND METHODS: 190 patients (190 eyes) with stationary myopia were examined and operated on. The follow-up period was 1 year after surgery. The main group consisted of patients who underwent myopia correction using sublamellar keratoablation technology using a solid-state laser Olimp 2000/213 — 92 eyes. The control group consisted of patients after FemtoLASIK, in whom ablation was performed using a Schwind Amaris 1050 rs laser (98 eyes). A comparative analysis was carried out according to modern criteria for refractive surgery.

CONCLUSIONS: The analysis of the clinical and functional results of myopia correction using the technology of sublamellar keratoablation, performed using the Olimp 2000/213 solid-state ablative laser and the Schwind Amaris 1050 rs excimer laser, showed a high comparability of the technologies.
