Abstract Details


The aim of our study was to investigate the efficacy and safety of Femtosecond penetrating keratoplasty at the patients with keratoconus.


Scientific research institute of eyes disease, Kazakhstan, Almaty


8 patients (8 eyes) with keratoconus II-III degree underwent complete diagnostic examination; there were no any contraindications for the surgical treatment. Femtosecond laser penetrating keratoplasty was performed by using VisuMax «Carl Zeiss Meditec» and treatment pack size M with optic diameter not less then 7,5 mm for recipient, and 8.0 mm for donor transplant. The average age was 29 years. Spherical equivalent refraction was average equal to (-) 6,5  0,11 D, cylinder (-) 4,25  0,12 D. UCVA in this group was average 0,08±0,08 and BCVA - 0,5±0.09. Observation period was 12 months.


The UCVA after operation improved in all patients in comparison to UCVA before it and was 0,25±0,14. We obtained diminishing of postoperative astigmatism and stabilization in corneal topography, spherical equivalent refraction was average equal to (-) 2.12 ±0,09 D, cylinder (-) 2.5±0,06. BCVA - 0,5±1.11. The postoperative period proceeded without any significant complications; the sutures were removed on 7-8 months after the operation. In all cases there was a transparent engraftment of the donor transplant.


The received results showed the effectiveness of and safety of Femtosecond penetrating keratoplasty at the patients with keratoconus.
