To evaluate distance, intermediate, and near visual performance in patients who had multifocal apodized diffractive intraocular lens (IOL) implantation. Spectacle independence and patient satisfaction were high, whereas unwanted photic phenomena were clinically acceptable. The AcrySof ReSTOR MA60D3 IOL demonstrated excellent near VA without compromising distance vision. Ninety-two percent of patients stated that they would choose to have the same lens implanted again after the first implant, and 95.7% answered likewise after the second implant. Glare and halos were reported as severe by only 8.5% and 4.2% of patients, respectively. In addition, 88.0% and 84.6% of ReSTOR subjects achieved spectacle independence for distance and near vision, respectively. At the 6-month postoperative visit, binocular (both eyes simultaneously) mean uncorrected distance and near logarithm of the minimum angle of resolution VAs for the MA60D3 were 0.04+/-0.14 and 0.09+/-0.12 (n = 118), respectively. Distance visual acuity (VA), near VA, spectacle dependence, unwanted visual symptoms, and patient satisfaction. Intraocular lens implant power ranged from 18.0 to 25.0 diopters (D) in 0.5-D increments. The mean preoperative patient age was 68.4+/-12 years. After phacoemulsification, the foldable 3-piece hydrophobic acrylic apodized diffractive IOL was implanted in the capsular bag using a Monarch injector with an A-cartridge. One hundred twenty-seven subjects implanted in cataractous eyes in an open multicenter study. Multicenter European study including university clinics, eye hospitals, and private ophthalmic surgical centers. To report the safety and effectiveness of the AcrySof ReSTOR apodized diffractive intraocular lens (IOL), model MA60D3, when implanted into the capsular bag. Una buena función visual en visión de lejos y de cerca bajo condiciones fotópicas La lente intraocular asférica AcrySof ReSTOR en pacientes miopes e hipermétropes proporciona CONCLUSIONES: La cirugía de cristalino transparente con No se encontraronĭiferencias estadísticamente significativas entre los valores pre y post-quirúrgicosĭe sensibilidad al contraste para cualquier distancia, frecuencia espacial o nivelĭe iluminación (p>0,002). Para visión de lejos y cerca en comparación a los valores pre-quirúrgicos. No corregida y con la mejor corrección tras la implantación de la lente intraocular RESULTADOS: Los pacientes de ambos grupos mostraron buenos niveles de agudeza visual Los resultados post-quirúrgicos a 6 meses fueron comparados con los pre-quirúrgicos. La función de sensibilidad al contraste fue medidaĪ tres diferentes niveles de iluminación (85, 5 y 2.5 cd/m²) antes y después de laĬirugía. Monocular en visión de lejos y de cerca, y la agudeza visual monocular no corregida Y a los 6 meses de la intervención quirúrgica la agudeza visual con la mejor corrección Los pacientes fueronĭivididos en dos grupos: miopes e hipermétropes. Se estudiaron 74 ojos de 37 pacientes tras ser sometidos a cirugía de cristalino transparenteīilateral con la lente intraocular AcrySof ReSTOR (SN6AD3 model). PROPÓSITO: El propósito de este estudio fue evaluar la sensibilidad al contraste antesĭe la extracción de cristalino transparente y tras la implantación de la lente intraocularĪsférica AcrySof®ReSTOR® (SN6AD3) bajo condiciones fotópicas y mesópicas. Visual function and yield good distance and near CS under photopic and mesopic conditions. With aspheric AcrySof ReSTOR IOL in myopic and hyperopic population provided good Lighting condition and spatial frequency (p>0.002). Were found between the values of CS pre and post-RLE at distance and near, at any Revealed that patients in both groups obtained good UCVA and BCVA after RLE at distanceĪnd near vision in relation to pre-surgery values. Results at 6 months were compared with those found before surgery. ![]() Monocular CS function was measuredĪt three different luminance levels (85, 5 and 2.5 cd/m²) before and after RLE. Were measured before and 6 months postoperatively. Monocular best corrected visual acuity at distance and near (BCVA and BCNVA, respectively) Uncorrected visual acuity at distance and near (UCVA and UCNVA, respectively) and The patient sample was divided into myopic and hyperopic groups. METHODS:Seventy-fourĮyes of 37 patients after RLE underwent bilateral implantation with the aspheric AcrySof Of the aspheric AcrySof®ReSTOR® (SN6AD3 model) intraocular lens (IOL). Mesopic conditions before and after refractive lens exchange (RLE) and implantation ![]() PURPOSE: To evaluate distance and near contrast sensitivity (CS) under photopic and ![]()
