Purpose. To work out a technology of a femtosecond laser assisted anterior lamellar keratoplasty and evaluate its safety and clinical efficiency. Material and м ethods. We report 13 cases of femtosecond laserassisted anterior lamellar keratoplasty. Both circular trepanation and lamellar dissection (80% of the corneal thickness) were performed with the IntraLase FS 60 kHz (AMO). Lamellar cut settings for the donor cornea were: spot/line separation 4/4μm, energy 1μJ; for the recipient 4/4μm and 2μJ, respectively. Eyes of 13 patients (11 with keratoconus, 2 with superficial corneal scarring) in the mean age 30.3±9.5 years were observed up to 2 year s after the surgery. Results. All corneal grafts were transparent, with the mean endothelial cell loss at 12 months equal to 3.5%. Evaluation of biomechanical properties of patients’ corneas 1 year after the surgery showed a reliable improvement of the CRF and CH meanings, comparable to preoperative data, from 5.7±1.28 and 6.92±1.32mmHg to 10.92±1 and 10.61±1.3mmHg (p&0.001), respectively, which correlates with the rates of normal cornea. Sutures were removed 6 months after surgery. The mean postoperative astigmatism at 12 months was 4.7±1.5 D. The mean UCVA at 12 months was 0.1±0.02 and the BCVA was 0.22±0.07. After 2 years the values were 0.2±0.03 and 0.3±0.05, respectively. The highest BCVA was achieved0.4 in 2 cases at 12 months. Conclusions. The obtained low postoperative visual acuity is explained, apparently, by irregularities of the donor-recipient interface and a pronounced light scattering occurred in it which leads to a reduction of the retinal image quality.
