ABSTRACT
AIM: To assess the medium term outcomes of Acrysof(®) toric intraocular lens implantation in 54 patients (54 eyes). METHODS: Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), preoperative astigmatism, residual postoperative astigmatism, and global average and model-specific intraocular lens (IOL) rotation grade were analyzed. RESULTS: At 2-months of follow-up,the mean UCVA was 0.83 (SD: 0.14) Snellen scale, with 73.9% of the patients ≥0.8, and 32.6% with 1.0. Mean BCVA achieved was 0.94 (SD: 0.10). Mean preoperatory astigmatism was -2.25 diopters (D) (SD: 0.78), and mean postoperative astigmatism was -0.32 D (SD: 0.56), with significant differences between both groups (p<0.001). Model-specific mean residual astigmatism was -0.1 D for T3, -0.27 D for T4 and -0.43 D for T5, without significant differences between the three models (p=0.483). Mean IOL-axis rotation grade was 3.87±3.25 degrees, with 91.6% of implanted lens within 10° of predicted axis. DISCUSSION: T3, T4 and T5 Acrysof(®) Toric intraocular lenses can correct preoperative astigmatism with a high success rate in terms of UCVA, and residual postoperative astigmatism, with minimum IOL-rotation grade at 2 months follow-up period.

PropósitoValorar los resultados a medio plazo del implante de lentes intraoculares tóricas Acrysof en 54 pacientes (54 ojos).MétodoLos parámetros analizados fueron mejor agudeza visual sin corrección (AVSC) y agudeza visual mejor corregida (AVMC), astigmatismo preoperatorio y residual postoperatorio, y rotación de la lente globalmente y en cada modelo de lente intraocular empleado.ResultadosA los 2 meses del seguimiento, la AVSC media total fue de 0,83 (DS: 0,14) Snellen, estando el 73,9% de ellos con AVSC ≥0,8 y el 32,6% en 1,0. La AVMC fue de 0,94 (DS: 0,10). El astigmatismo medio preoperatorio fue de -2,25 dioptrías (D) (DS: 0,78), siendo el astigmatismo medio postoperatorio total de -0,32 D (DS: 0,56), con diferencia estadísticamente significativa entre ambos grupos (p<0,001). Desglosado por tipo de lente el astigmatismo fue -0,1 para las lentes T3, -0,27 D para las T4, y -0,43 para las T5, sin diferencias significativas entre los grupos estudiados (p=0,483). La rotación media del eje de la LIO respecto al eje previsto fue de 3,87±3,25 grados, con rotación menor a 10° en el 91,6% de las LIO implantadas.DiscusiónLas lentes tóricas modelo Acrysof T3, T4 y T5 permiten corregir el astigmatismo preoperatorio con un porcentaje elevado de éxito en lo que a AVSC y astigmatismo residual postoperatorio se refiere, con un mínimo grado de rotación de la lente a los 2 meses(AU)
