Treatment of Severe Post-Prostatectomy Stress Urinary Incontinence Using Advance Sling
2010
Severe stress urinary incontinence (SUI) is usually treated by the implant of artificial sphincter positioned around bulbar urethra. AdVance sling is a functional, non-obstructive, anti-incontinence device that showed good results especially for mild and moderate SUI. We present our experience with AdVance sling in 7 patients with severe SUI unfit for artificial sphincter. Our results, after a follow-up of more than 6 months, showed a continence rate of 28% and an improvement rate of 43%, while 2 patients did not show any benefit. The success of AdVance sling depends on the integrity of urethral sphincter and can be applied also in selected cases for the treatment of severe post-prostatect…
Intermediate visual function with different multifocal intraocular lens models
2009
Purpose To compare visual acuity at different distances after bilateral implantation of 1 of 4 multifocal intraocular lenses (IOLs). Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Methods This study evaluated consecutive patients who had bilateral implantation of a spherical multifocal IOL with a +4.00 diopter (D) addition (add) (AcrySof ReSTOR SN60D3) or an aspheric multifocal IOL with a +4.00 D add (AcrySof ReSTOR SN6AD3), +3.75 D add (Acri.LISA 366D), or +3.00 D add (AcrySof ReSTOR SN6AD1). Six months postoperatively, binocular measurement of corrected distance visual acuity (CDVA) at 4 m, corrected near visual acuity (CNVA) at 40 cm, and corrected intermediate visual …
Visual acuity comparison of 2 models of bifocal aspheric intraocular lenses.
2008
Purpose To compare visual acuity after bilateral implantation of 2 models of multifocal aspheric intraocular lenses (IOLs). Setting Fernandez-Vega Ophthalmological Institute, Oviedo, and University of Valencia, Valencia, Spain. Methods Prospective study of patients who had bilateral implantation of an AcrySof ReSTOR SN6AD3 IOL (Group 1) or an Acri.LISA 366D IOL (Group 2). Six months postoperatively, binocular uncorrected and best corrected distance visual acuity, uncorrected-distance and best distance-corrected near visual acuity, best corrected intermediate visual acuity, and the defocus curve were measured in both IOL groups. Results Group 1 comprised 36 eyes (18 patients) and Group 2, 40…
Visual Acuity and Contrast Sensitivity in Eyes Implanted with Aspheric and Spherical Intraocular Lenses
2009
Purpose To compare visual acuity and contrast sensitivity (CS) in eyes implanted with aspheric and spherical intraocular lenses (IOLs) after cataract surgery. Design Randomized, prospective study. Participants Five hundred twenty-four eyes from 262 cataract surgery patients implanted with 2 IOL models: the AcrySof IQ (262 eyes) and AcrySof SN60AT (262 eyes; Alcon Laboratories, Fort Worth, TX). Methods High-contrast photopic best-corrected distance visual acuity (BCVA) and CS under photopic (85 cd/m 2 ) and mesopic (6 cd/m 2 ) conditions were measured. Pupil diameter was analyzed for distance vision under both lighting conditions. Follow-up was carried out for 6 months in all patients. Main …
Refractive and Visual Results after Implantation of the AcrySof ReSTOR IOL in High and Low Hyperopic Eyes
2009
To assess the differences in refractive and visual results obtained in eyes with high and low hyperopia after implantation of a multifocal intraocular lens (IOL).A prospective study was performed on 172 hyperopic eyes implanted with the AcrySof Re-STOR Natural (SN60D3) IOL. Two groups were created, high and low hyperopes (86 eyes in both cases). We analyzed monocular visual acuity for distance and near, with and without distance correction. Photopic and mesopic contrast sensitivity (CS) were also assessed. All measurements were performed at 6 months after surgery.Monocular best distance-corrected visual acuity was 0.01+/-0.03 logMAR for low hyperopes and 0.04+/-0.10 logMAR for high hyperope…
Optical quality of the eye after lens replacement with a pseudoaccommodating intraocular lens
2007
To examine the optical quality of healthy presbyopic eyes before and after implantation of the pseudoaccommodating AcrySof ReSTOR Natural intraocular lens (IOL) (Alcon Laboratories) by measuring visual acuity and wavefront aberrations.University of Valencia, Fernández-Vega Ophthalmological Institute, Valencia, Spain.Monocular refraction and photopic distance (6 m) and near (0.33 m) visual acuities were determined before and after clear lens extraction with bilateral AcrySof ReSTOR Natural IOL implantation in 30 hyperopic eyes (+0.50 to +4.00 diopters [D]) of presbyopic patients with low astigmatism (or = 1.00 D). Postsurgical binocular visual acuity was measured over a range of effective di…
Visual Function after Implantation of a Presbyopia-Correcting Trifocal Intraocular Lens
2019
<b><i>Purpose:</i></b> To evaluate distance, intermediate, and near visual performance in patients implanted with a trifocal aspheric presbyopia-correcting intraocular lens (IOL). <b><i>Methods:</i></b> Forty patients were bilaterally implanted with the AcrySofIQ PanOptix IOL after femtosecond laser-assisted lens surgery. Binocular best corrected distance visual acuity (CDVA) (4 m), best distance-corrected near visual acuity (DCNVA) (40 and 30 cm), best corrected distance intermediate visual acuity (DCIVA) (70, 60, and 50 cm), binocular distance contrast sensitivity under photopic conditions (85 cd/m<sup>2</sup>), and defocus curve…
Effect of partial and full correction of corneal spherical aberration on visual acuity and contrast sensitivity
2008
A 60-year-old white man had cataract surgery with an AcrySof IQ intraocular lens (IOL) implanted in the right eye and a Tecnis IOL implanted in the left eye. The ocular spherical aberration (SA) target for a 6.0 mm pupil was +0.10 microm for the right eye and 0 microm for the left eye. After surgery, the ocular SA in the right eye was significantly higher than that in the left eye (+0.112 microm +/- 0.002 [SD] versus +0.021 +/- 0.003 microm; P.001). No between-eye difference in the best corrected visual acuity and photopic contrast sensitivity was found. The contrast sensitivity was significantly better in the eye with the AcrySof IQ IOL at 12 and 18 cpd under mesopic conditions. The best c…
Pseudoaccommodating intraocular lens implantation in patients with irregular nonreactive pupils.
2007
We report 3 patients implanted with the AcrySof ReSTOR pseudoaccommodating intraocular lens (IOL) who had irregular nonreactive pupils as a consequence of pupil stretching during phacoemulsification. Despite the pupils, the visual acuity at distance and near was not compromised. The outcome in these cases suggests that an irregular nonreactive pupil is not an exclusion criterion for pseudoaccommodating IOL implantation.
Late postoperative opacification of MemoryLens hydrophilic acrylic intraocular lenses Case series and review
2003
Abstract Purpose: To report clinical and spectrographic analyses of 2 explanted hydrophilic acrylic intraocular lenses (IOLs). Setting: John A. Moran Eye Center, Salt Lake City, Utah, USA, and Johannes Gutenberg-University, Department of Ophthalmology, Mainz, Germany. Methods: We report 6 cases of opacification of MemoryLens ® IOLs (Ciba Vision) that occurred approximately 2 years after implantation. The anterior and posterior surfaces of the IOLs had a white, frosted appearance, and the IOLs' interior looked brown, similar to the appearance of a brunescent cataract. Two of the IOLs were explanted because of a significant decrease in visual acuity. The IOLs were sent for further clinicopath…
