Small-incision lenticule extraction for moderate to high myopia: Predictability, safety, and patient satisfaction

摘要: Purpose To present initial clinical experience with small-incision lenticule extraction for the treatment of moderate to high myopia. Setting Department Ophthalmology, Aarhus University Hospital, Aarhus, Denmark. Design Prospective study. Methods For extraction, an intrastromal was cut a femtosecond laser and manually extracted without creation flap. Patients were treated followed 3 months. Only 1 randomly chosen eye each patient used in statistical analyses. Results The study enrolled 144 patients. mean preoperative spherical equivalent −7.18 diopters (D) ± 1.57 (SD). Of eyes emmetropia as target refraction, 40% had uncorrected distance visual acuity 0.1 logMAR or less day after surgery; this increased 73% at corrected (CDVA) improved significantly from −0.01 (logMAR) preoperatively −0.03 months postoperatively.
