| description | Purpose: to compare in vivo histomorphologic structure of cornea after the FemtoLASIK procedure using femtolaser systems Femto Visum (Russia) and Femto LDV Z6 (Switzerland). Patients and methods: The study was carried for 70 eyes from 70 patients with low to moderate myopia after FemtoLASIK procedure. Group 1 (Femto Visum) included 36 eyes (n = 36) there the flap were formed using femtolaser Femto Visum («Optosystems», Russia), group 2 (Femto LDV Z6) included 34 eyes (n = 34) and Femto LDV Z6 was used («Ziemer Ophthalmic Systems AG», Switzerland). The excimer laser ablation was performed with Microscan Visum system («Optosystems», Russia) in both groups. The Femto Visum and Femto LDV Z6 groups were comparable in terms of pre-operative data (age, sex, corneal curvature, central corneal thickness, sphere, cylinder, spherical equivalent) (p > 0.05). In vivo histomorphological structure of the cornea was examined using confocal microscope Confoscan 4 (Nidek, Japan) 1 week, 1, 3, 6, and 12 months after FemtoLASIK. The endothelial cell density (ECD) was measured with endothelial microscope (EM-3000, Tomey, Japan) before surgery and 12 months after FemtoLASIK. Results: The main in vivo histomorphological cornea changes occurred in the anterior and middle layers of the corneal stroma during post-operative period in both groups (Femto Visum and Femto LDV Z6). The underlying corneal structures remained intact. There was no statistically significant difference between the two groups (p > 0.05). Twelve months postoperatively, the loss of ECD was 0.31 % in the Femto Visum group and 0.33 % in the Femto LDV Z6 group (p > 0,05). Conclusions: FemtoLASIK procedures using Femto Visum (Russia) and Femto LDV Z6 (Switzerland) lead to similar histomorphological cornea changes in post-operative period (p > 0.05) and they are safe for corneal structure in the treatment of myopia. |
