Abstract

Purpose. To present a clinical case of FemtoLASIK operation after vacuum loss during CLEAR technique. Methods. During the CLEAR operation for correction of middle degree myopia there was a vacuum loss during the formation of the lower surface of the lenticule. The surgeon decided not to proceed with further CLEAR surgery, but to switch to FemtoLASIK surgery with the formation of a surface flap with a diameter larger than the lenticule diameter and a thickness smaller than the initial planned lenticule depth. Results. The operation was performed without complications, according to the standard protocol, without changing the energy parameters at the femtosecond stage of epithelial-stromal flap formation. When assessing clinical and functional parameters on the next day and in 7 days the uncorrected visual acuity of 1.0 and the planned target refraction were noted. Conclusion. The combination of femtosecond laser technologies allows to solve intraorefractive problems without loss of efficiency and safety. Key words: vacuum loss, femtosecond laser, refractive lenticule extraction
