Correction of myopia by the method of corneal lenticule refractive extraction using a lowenergy femtosecond laser

Purpose: to evaluate the safety and effectiveness of the myopia correction by corneal lenticule refractive extraction. Material and Methods. A prospective study included 24 patients (24 eyes) (26.8±4.6 years old) who were operated at the S. Fedorov Eye Microsurgery Federal State Institution for myopia correction by corneal lenticule refractive extraction. Results. One week after the operation, there was an improvement in visual acuity (VA) (up to 0.9 (0.7; 1.0)), which remained throughout the observation period. After a month, the uncorrected VA was 1.0 (1.0; 1.0). There were no intraoperative or postoperative complications. Loss of the maximum corrected VA was observed in 20.8 %. There was a decrease in the average corneal thickness from 555.9±28.2 μm before surgery to 464.8±26.9 μm a week after surgery (p<0.05). The cost of tissue per 1 diopter was 17 microns. Conclusion. Correction of myopia by the method of corneal lenticule refractive extraction meets modern concepts about the effectiveness and safety.
