ResumenObjetivoDeterminar la eficacia y la seguridad del LASIK en el tratamiento de la ambliopía por anisometropía en pacientes adultos.MétodosSerie de casos. Estudiamos a 12 pacientes adultos ambliopes por anisometropía a los cuales se realizó LASIK monocular de nuestro servicio de Córnea y Cirugía Refractiva. Evaluamos el error refractivo pre y postoperatorio, equivalente esférico (ES), la agudeza visual sin corrección (AVSC) y la agudeza visual mejor corregida (AVMC). La agudeza visual medida por la cartilla de Snellen fue convertida a LogMAR con fines de análisis estadístico.ResultadosLa edad promedio fue de 31.92 (± 12.13) años. El ES preoperatorio promedio en el ojo tratado fue de –3.49 D (± 3.24), el ES promedio del ojo no tratado fue de 0.25 D (± 0.30). La AVSC preoperatoria fue de 1.12 (± 0.3) LogMAR y la AVMC preoperatoria fue 0.31 (± 0.1) LogMAR. El seguimiento promedio fue de 19.1 (rango 6-74) meses. El ES promedio postoperatorio disminuyó a –0.28 (± 0.48). Cinco pacientes (42%) ganaron una línea de visión, un (8%) paciente ganó 2 líneas de visión y un (8%) paciente ganó 3 líneas de visión. El resto (42%) permaneció sin cambios comparados a la AVMC preoperatoria. Se encontraron diferencias estadísticamente significativas entre la AVSC preoperatoria (1.12 [±0.3]) y la AVSC postoperatoria (0.27 [±0.1]) (p=0.002, Z-Wilcoxon) y entre la AVMC postoperatoria (0.23 [±0.12]) y la AVMC preoperatoria (0.31 [±0.1]) (p=0.014, Z-Wilcoxon). No hubo complicaciones relacionadas con la cirugía.ConclusionesLa cirugía refractiva monocular en pacientes con ambliopía por anisometropía es una opción terapéutica segura y efectiva que ofrece resultados visuales satisfactorios, preservando o incluso mejorando la AVMC preoperatoria.AbstractPurposeTo investigate the efficacy and safety of LASIK for the correction of anisometropic amblyopia in adult patients.MethodsA retrospective, case series. We found 12 amblyopic adult patients that underwent monocular LASIK for anisometropía in our Cornea and Refractive service. We evaluated the preoperative and postoperative refractive error, spherical equivalent (SE), uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA). Snellen visual acuity measurements were converted to LogMAR for statistical purposes.ResultsThe mean age was 31.92 (±12.13) years. The average preoperative SE in the treated eyes was -3.49 (±3.24), the average SE of the untreated eye was 0.25(±0.30). Preoperative UCVA was 1.12 (±0.3) and average preoperative BCVA was 0.31 (±0.1). All patients had LASIK with an average follow-up time of 19.1(6-74) months. The average postoperative SE decreased to -0.28 (±0.48). Five patients (42%) gained 1 line of vision, 1 (8%) patient gained 2 lines of vision, 1 (8%) patient gained 3 lines of vision and the rest (42%) remained unchanged compared to preoperative BCVA. Statistically significant differences were observed between the preoperative UCVA [1.12 (±0.3)] with the postoperative UCVA [0.27 (±0.1)](p=0.002, Z-Wilcoxon) and between the postoperative BCVA [0.23 (±0.12)] with the preoperative BCVA [0.31 (±0.1)] (p=0.014, Z-Wilcoxon). There were no complications related to the surgical procedures.ConclusionsMonocular refractive surgery in adult patients with anisometropic amblyopia is a safe and effective therapeutic option that offers a satisfactory visual outcome, preserving or even improving the preoperative BCVA.
