Purpose
To share the initial clinical results of lenticule extraction refractive surgery (CLEAR) using Ziemer's Femto LDV Z8 laser.
Setting
Retrospective
Methods
The clinical results of 48 eyes of 25 patients who underwent surgery from October 2021 to January 2022 were retrospectively reviewed during 1 month after surgery. Size of lenticule was 6.5mm, cap thickness was 120-130um, and the remaining corneal thickness was 300um or more. Visual acuity and refractive error were measured at 1 day, 1 week, and 1 month after surgery, and change of corneal curvature and corneal thickness were measured through corneal topography.
Results
The average age was 27±5 years, and the gender was 18 males and 7 females. Visual acuity improved from 0.086±0.14 to 0.940±0.10 (uncorrected) and 0.992±0.039 (corrected) for one month after surgery. Refractive error decreased from -3.782 ±1.21D to +0.01±0.31D. Astigmatism decreased from -0.819±0.64D to -0.140±0.29D. The corneal curvature decreased from 43.246±1.41D to 39.564±2.12D, and the corneal thickness decreased from 552.3±33.4um to 451um±19.2um.
Conclusions
Refractive error was effectively corrected by lenticule extraction using Femto LDV Z8, and visual acuity was significantly restored after surgery. No serious complications were observed.
