ResumenObjetivoEvaluar el resultado visual a distancias lejana, intermedia y cercana, presencia de disfotopsias, aberrometría corneal y satisfacción visual del paciente tras el implante de un lente intraocular trifocal difractivo.Material y métodosEstudio prospectivo, longitudinal y observacional que incluyó a pacientes sometidos a cirugía de facoemulsificación más implante de lente intraocular trifocal difractivo por catarata o disfunción de cristalino. Se evaluó agudeza visual lejana, intermedia y cercana al mes de la cirugía, así como la presencia de disfotopsias percibidas por el paciente, aberrometría corneal y su nivel de satisfacción visual.ResultadosSe evaluaron un total de 94 ojos en 52 pacientes. En el 80.7% se realizó cirugía bilateral y en el 19.3% de un solo ojo. La agudeza visual lejana, intermedia y cercana al mes de la cirugía fue de 0.06±0.15, 0.04±0.10 y −0.03±0.10 LogMAR, respectivamente, con un equivalente esférico residual de −0.31±0.60. El 23.4% de los pacientes refirió deslumbramiento, el 1.1% fotopsias y el 1.1% ambas. El 97% de los pacientes se refirieron satisfechos tras el implante del lente intraocular. No existieron cambios significativos en las aberraciones ópticas pre- y postoperatorias.ConclusionesEl implante de un lente intraocular trifocal difractivo es capaz de proporcionar una excelente visión lejana, intermedia y cercana, con escasas aberraciones ópticas, permitiendo una mejor calidad visual útil en actividades desarrolladas a diferentes distancias.AbstractPurposeTo assess long, intermediate and near visual acuity, dysphotopsia, corneal aberrometry and patient's visual satisfaction after the implantation of a trifocal diffractive intraocular lens.MethodsProspective, longitudinal, observational study that included patients who underwent phacoemulsification followed by trifocal diffractive intraocular lens implantation due to cataract or dysfunctional lens syndrome. Long, intermediate and near visual acuity after one month of surgery was measured, presence of dysphotopsia, corneal aberrometry and visual satisfaction described by the patient.ResultsA total of 94 eyes in 52 patients were evaluated. 80.7% underwent bilateral phacoemulsificacion. Long, intermediate and near visual acuity after one month was 0.06±0.15, 0.04±0.10 y -0.03±0.10 in LogMAR scale respectively, with a spherical equivalent of -0.31±0.60. 23.4% presented glare, 1.1% photopsias and 1.1% both. 97% of the eyes were satisfied after the IOL implantation. There was no significant changes if preoperative and postoperative aberrometry.ConclusionTrifocal diffractive intraocular lens provide excellent long, intermediate and near visual acuity, with few optical aberrations, allowing better visual quality applied to different distances.
