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.
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.
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 (<0.05). The cost of tissue was 17 microns per 1 diopter.
The obtained results indicate the high effectiveness of the correction of moderate and high myopia using the Ziemer LDV Z8 device.
矫正中度和高度近视的主要方法之一是角膜透镜切除术。齐默公司正在为飞秒激光系统FEMTO LDV Z8平台增加一项新应用——Lenticule CLEAR，旨在通过角膜透镜切除术治疗近视。目的——研究使用齐默LDV Z8设备进行角膜透镜切除术矫正中度和高度近视的安全性和有效性。
前瞻性研究纳入了2020年1月在圣彼得堡费奥多罗夫国家医学研究中心“眼显微外科”科研生产联合体，使用齐默LDV Z8设备接受中度和高度近视手术的24例年龄为26.8±4.6岁（24只眼）的患者。
使用齐默LDV Z8设备矫正中度和高度近视后，患者术后一周视力稳定改善，且在整个术后期间保持稳定。对在齐默LDV Z8平台接受中度和高度近视手术的患者进行为期1个月的动态随访显示，术后一周未矫正视力的中位数为0.9[0.7；1.0]，术后1个月为1.0[1.0；1.0]。在齐默LDV Z8平台接受手术的患者无术中或术后并发症，79.2%的患者最大矫正视力也未丧失。术前平均角膜厚度为555.9±28.2μm，术后一周显著降至平均464.8±26.9μm（<0.05）。组织切除量为每1屈光度17微米。
所获结果表明使用齐默LDV Z8设备矫正中度和高度近视具有高效性。
