Results of corneal lenticule extraction for correction

One of the main methods for correcting moderate and high myopia is corneal lenticule extraction. Ziemer is adding a new application to the FEMTO LDV Z8 platform - Lenticule CLEAR, designed to treat myopia by corneal lenticule extraction. Purpose - to study the safety and effectiveness of corneal lenticule extraction using the Ziemer LDV Z8 device for the correction of moderate and high myopia. MATERIAL AND METHODS The prospective study included 24 patients aged 26.8±4.6 years (24 eyes) who underwent surgeries for moderate and high myopia on the Ziemer LDV Z8 device at the S.N. Fyodorov National Medical Research Center «MNTK «Eye Microsurgery» in January 2020. RESULTS After correction of moderate and high myopia using the Ziemer LDV Z8 device, patients showed stable improvement in visual acuity one week after surgery, which remained throughout the postoperative period. Dynamic 1-month follow-up of patients operated on the Ziemer LDV Z8 platform for moderate and high myopia showed that the median value of uncorrected visual acuity one week after surgery was 0.9 [0.7; 1.0], and after one month - 1.0 [1.0; 1.0]. Patients operated on the Ziemer LDV Z8 platform had no intra- or postoperative complications, 79.2% of patients also had no loss of maximum corrected visual acuity. The mean corneal thickness before surgery was 555.9±28.2 μm, it significantly decreased to an average value of 464.8±26.9 μm one week after surgery (p<0.05). The cost of tissue was 17 microns per 1 diopter. CONCLUSION The obtained results indicate the high effectiveness of the correction of moderate and high myopia using the Ziemer LDV Z8 device.
