Purpose
To evaluate safety and efficacy of Low-energy laser refractive lenticule extraction-SmartSight by Schiwind for correcting moderate myopia.
Setting
Refractive lenticule extraction with SmartSight by Schiwind eye-tech-solutions were performed by experienced surgeon.
All patients were moderate myopia (-1.5 ~-6.0D) with no ocular complications.
Conventional energy settins is 720 -750mj/cm2. Low energey setting is under 680 mj/cm2
No intraoperative complications of leticule surgery including retained lenticule fragments, tears of incision, or improper dissection occurred.
Methods
A total of 74 patients (148 eyes) with moderate myopia were included for refractive lenticule extraction: 102 eyes were operated with low energy (600-700 mj/cm2) ( L-energy group) and 46 eyes with conventional energy. (720-750mj/cm2) (c-energy group).
Results
Mean patient age was 24.03 ± 7.1 years. Preoperative mean spherical equivalent error was -5.74 ± 1.76 Ds. Uncorrected distance visual acuity (logMAR UDVA) 1 day and 1 week postoperatively was significantly better in L-energy group than in C-energy group (P < .001 and P = .005, respectively). At POD1, astigmatism was -0.12 ± 0.08D lower for low energy group (p < .005) The mean spherical equivalent at 1 month was 0.16 ± 0.66 D in both group with no statistical differences. The mean spherical equivalent of refraction to the target was 95% within ± 0.50 D in both group.
Conclusions
Low energy setting of under 700 mj/cm2 facilitates better visual acuity in the early postoperative period without increased dissecting difficulty.
