Visual and Refractive Outcomes in Hyperopic Pseudophakic Patients Implanted with the Acri.LISA 366D Multifocal Intraocular Lens

2009

Our purpose was to assess the visual quality after bilateral implantation of the Acri.LISA 366D intraocular lens (IOL; Carl Zeiss Meditec, Jena, Germany) in patients with hyperopia. We did a prospective and nonrandomized study. One hundred and seventy eyes of 85 patients had bilateral implantation of the Acri.LISA 366D IOL. The patients were divided into 2 groups: low to moderate hyperopia (IOL power, 21 to 24.5 diopters [D]) and high hyperopia (IOL power, 25 to 36 D). Monocular and binocular best spectacle-corrected visual acuity (BSCVA), best distance-corrected near visual acuity (BCNVA), binocular best distance-corrected intermediate visual acuity (VA), and distance contrast sensitivity …

Visual acuity tolerance to residual refractive errors in patients with an apodized diffractive intraocular lens.

2007

To assess visual acuity tolerance to defocus caused by residual refractive errors after clear lens extraction (CLE) with apodized diffractive intraocular lens (IOL) implantation.Fernández-Vega Ophthalmological Institute, Oviedo, Spain.In this prospective study, 150 eyes of 75 consecutive patients who had bilateral CLE with implantation of an AcrySof ReSTOR Natural IOL (Alcon) were evaluated. The eyes were divided into 2 groups: myopia and hyperopia. Residual refractive errors were analyzed using vector analysis. Monocular and binocular uncorrected distance visual acuity, best corrected distance visual acuity, uncorrected distance near visual acuity, and best distance-corrected near visual a…

Foldable toric intraocular lens for astigmatism correction in cataract patients.

2007

PURPOSE: To evaluate the results of AcrySof toric intraocular lens (IOL) (Alcon) implantation to correct preexisting astigmatism in patients having cataract surgery. SETTING: Ophthalmology Service, Donostia Hospital, San Sebastian, Spain. METHODS: This prospective observational study included 30 eyes of 15 consecutive patients with more than 1.00 diopter (D) of preexisting corneal astigmatism having cataract surgery. Bilateral implantation of the AcrySof toric IOL was performed after phacoemulsification. The uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), residual refractive sphere, residual keratometric and refractive cylinders, and toric IOL axis were measured. RESU…

Identification of optimal device combinations for the chimney endovascular aneurysm repair technique within the PERICLES registry

2018

Abstract Objective The ideal stent combination for chimney endovascular aneurysm repair remains undetermined. Therefore, we sought to identify optimal aortic and chimney stent combinations that are associated with the best outcomes by analyzing the worldwide collected experience in the PERformance of chImney technique for the treatment of Complex aortic pathoLogiES (PERICLES) registry. Methods The PERICLES registry was reviewed for patients with pararenal aortic disease electively treated from 2008 to 2014. Eleven different aortic devices were identified with three distinct subgroups: group A (n = 224), nitinol/polyester; group B (n = 105), stainless steel/polyester; and group C (n = 69), n…

Supracoronary ascending aortic replacement in patients with acute aortic dissection type A: What happens to the aortic root in the long run?

2013

ObjectiveOur objective was to determine long-term outcome predictors for patients with acute aortic dissection type A (AADA) and aortic root involvement.MethodsFrom 2001 through 2009, 119 of 152 patients operated on for AADA at a tertiary medical center underwent supracoronary ascending aortic replacement (52 women; mean age, 61 ± 15 years). Those with at least 1-year follow-up (n = 97) were retrospectively assessed for preoperative aortic root disease. Follow-up data were assessed for evidence of new-onset aortic root disease by computed tomography and echocardiography, and for reoperation for aortic root disease.ResultsMedian follow-up was 33.8 months (range, 0-112 months). Twenty-six (27…

XEN-augmented Baerveldt Implantation for Refractory Childhood Glaucoma: A Retrospective Case Series

2019

Background Tube implants can lead to long-term decompensation of the cornea after decades, in particular in complicated childhood glaucoma, because of a variety of causes including contact between the tube tip and the corneal endothelium. The augmentation of a XEN implant with a Baerveldt (250) tube implant, introduced 2016 by Mermoud et al for refractory glaucoma in adult patients, may reduce this risk in children. In our retrospective study, we report on the XEN-augmented Baerveldt (250) tube implant in children. Patients and methods Ten consecutive patients with refractory childhood glaucoma who underwent XEN-augmented Baerveldt implantation by a single surgeon (F.G.) between January 201…

Abstract Objective The objective of this study was to analyze the outcome of a contemporary series of femoropopliteal bypass operations with the glutaraldehyde denatured polyester mesh-reinforced ovine collagen prosthesis (OCP; Omniflow II [LeMaitre Vascular, Inc, Burlington, Mass]). The experience of two tertiary centers regarding long-term graft function, secondary reinterventions, and biodegeneration of the OCP prosthesis is presented. Methods Between January 2006 and January 2014, a series of 205 consecutive operations with the OCP in the femoropopliteal position (54 above knee and 151 below knee) were performed in 194 patients in 202 limbs for disabling claudication (72), chronic criti…

Use and durability of femoral vein for autologous reconstruction with infection of the aortoiliofemoral axis.

2014

Objective To analyze early and late mortality, venous morbidity, reinfection, and freedom from reintervention after using the femoral vein (FV) for vascular reconstruction with infection of the aortoiliofemoral axis. Methods By reviewing our database, 86 patients could be identified with implantation of FV grafts in infected fields between November 1995 and July 2012. The patient records were retrospectively analyzed and follow-up information obtained from patients or their general physician. Seventy-one patients presented with prosthetic graft infection and 15 with an infected aneurysm. For data analysis, patients were divided into an aortoiliac (n = 67) and a femoral group (n = 19).
