Abstract
Evaluar la estabilidad rotacional y su influencia en la agudeza visual postoperatoria de diferentes lentes intraoculares tóricas monofocales y multifocales. Crear un Sistema de marcado que permita implantar la lente tórica en el eje correcto en el acto quirúrgico. Material y método: Se realizó un estudio prospectivo intervencional. Se incluyeron noventa y uno pacientes con una edad media de 71.65±11.82 años a los que se les implantó una lente intraocular tórica LIOs) tras facoemulsificación. Se implantaron tres LIOs monofocales tóricas (Lentis LT, EnVista toric and Acrysoft IQ toric) y una lente multifocal tórica (Acrysoft IQ Restor). Se tomaron imágenes preoperatorias y postoperatorias para calcular el desalineamiento (misalignment) debido al sistema de marcaje. Para evaluar la rotación en las distintas visitas postoperatorias se tomaron fotografías a la hora, al día, a los 7 días y a los 30 días tras la intervención quirúrgica. La refracción, la mejor agudeza visual sin refracción (UDVA) y la mejor agudeza visual corregida (CDVA) se midieron en la visita postoperatoria al mes de la cirugía...
To evaluate rotational stability and its influence on post-operative visual acuity of different monofocal and multifocal toric IOLs. To devise a marking system that allows the positioning of the toric IOL in the right axis of orientation upon implantation, as part of the surgical procedure. Methods: A Prospective interventional study was designed. Ninety-one patients with a mean age of 71.65±11.82 years were implanted with toric intraocular lenses (IOLs) after phacoemulsification. Three monofocal toric IOLs (Lentis LT, EnVista toric and Acrysoft IQ toric) and one multifocal toric IOL (Acrysoft IQ Restor) were implanted. Pre-operative and post-operative images were taken to calculate the misalignment due to the marking method. To evaluate rotation in the different follow-up visits, another photograph was taken 1 hour, 1 day, 7 days and 30 days post-surgery. Refraction, uncorrected distance visual acuity (UDVA) and best corrected distance visual acuity (CDVA) were measured 30 days post-surgery...
