Closed foldable capsular rings
2004
A new foldable capsular tension and bending ring system with a sharp-edged design is described. The closed foldable capsular rings (CFCR) consist of 8 hydrophobic and 8 hydrophilic ring segments. The CFCRs have a 9.2 mm minimum overall diameter. The CFCRs were inserted using various cartridge systems or a two-folded technique with a forceps. The CFCRs were implanted after phacoemulsification through a small (1.6 to 3.2 mm) incision in 104 human adult eyes without intraoperative complications. No postoperative complications such as capsule folds or inward bending were observed over a 6-month follow-up. Posterior capsule opacification was minimal or absent in all eyes.
Contrast sensitivity and color perception with orange and yellow intraocular lenses
2012
To evaluate contrast sensitivity function (CSF) and color vision after implantation of either orange or yellow-tinted intraocular lenses (IOLs).Fifty-six eyes of 28 cataract patients who had bilateral implantation of orange-tinted (PC440Y Orange, Ophtec), yellow-tinted (AcrySof Natural SN60AT, Alcon), or clear (AcrySof SA60AT, Alcon) IOLs were examined. Six months postoperatively, monocular CSF under photopic and mesopic (with and without glare) conditions were measured using the Functional Visual Analyzer. Color discrimination was determined with the Farnsworth-Munsell 100-Hue test.Patients implanted with orange-tinted, yellow-tinted, or clear IOLs displayed similar CSF values, with no sta…
Influence of trifocal intraocular lenses on standard autorefraction and aberrometer-based autorefraction.
2019
To study the agreement between manifest refraction and objective refraction measured with two autorefractor models and an aberrometer in eyes implanted with a trifocal diffractive intraocular lens (IOL).IOA Madrid Innova Ocular, Madrid, Spain.Prospective comparative cohort study.An autorefractor keratometer (KR-8800), based on a Scheiner double pinhole, and a 3-dimension wavefront topography aberrometer system (OPD-Scan III), based on the scanning-slit retinoscopy principle, were used to obtain objective refraction readings. In addition, lower-order Zernike coefficients (Z) were used to calculate objective refraction. A set of 7 different results was obtained in power vector notation (spher…
Efficacy and safety of combined diclofenac 0.1 % and gentamicin 0.3 eyedrops after phacoemulsification
1997
To study the efficacy of combined diclofenac 0.1% and gentamicin 0.3% (Digen) eyedrops to treat postoperative inflammation and prevent ocular infection in eyes having phacoemulsification.Department of Ophthalmology, University of Milan, San Paolo Hospital, Milan; Eye Clinic, University of Verona; and Department of Ophthalmology, University of Palermo, Italy.This double-masked, randomized, clinical trial comprised 90 patients; 45 received Digen and 45, gentamicin 0.3% eyedrops. The main outcome measure of the study was the reduction in signs and symptoms of inflammation, graded on a four-point scale. Also assessed were the presence of bacteria in the conjunctival swab and the proportion of p…
A Randomized Trial of a Schlemm's Canal Microstent with Phacoemulsification for Reducing Intraocular Pressure in Open-Angle Glaucoma
2014
Purpose To assess the safety and effectiveness of the Hydrus Microstent (Ivantis, Inc, Irvine, CA) with concurrent cataract surgery (CS) for reducing intraocular pressure (IOP) in open-angle glaucoma (OAG). Design Prospective, multicenter, randomized, single-masked, controlled clinical trial. Participants One hundred eyes from 100 patients 21 to 80 years of age with OAG and cataract with IOP of 24 mmHg or less with 4 or fewer hypotensive medications and a washed-out diurnal IOP (DIOP) of 21 to 36 mmHg. Methods On the day of surgery, patients were randomized 1:1 to undergo CS with the microstent or CS alone. Postoperative follow-up was at 1 day, 1 week, and 1, 3, 6, 12, 18, and 24 months. Wa…
European study of the efficacy of a cross-linked gel stent for the treatment of glaucoma
2020
indexation en cours.; PURPOSE: This study investigated the efficacy and safety of a cross-linked collagen stent (XEN 45) with or without cataract surgery in the treatment of glaucoma. SETTING: Real-life setting. DESIGN: Prospective, open-label, multicenter clinical trial. METHODS: Eligible patients with glaucoma inadequately controlled by treatment, or poor compliance or intolerance to topical therapy were included. Patients were divided into those with implant only (solo group; phakic and pseudophakic patients) and implant combined with cataract surgery (combo group). Differences in average intraocular pressure (IOP) and number of medications between baseline and study end (12 months), and…
Eubacterial PCR for Bacterial Detection and Identification in 100 Acute Postcataract Surgery Endophthalmitis
2008
International audience; PURPOSE: To evaluate eubacterial PCR compared with conventional cultures for detection and identification of bacterial agents in ocular samples from patients with acute postcataract endophthalmitis. METHODS: Broad-range eubacterial PCR amplification was used, followed by direct DNA sequencing in ocular samples (aqueous humor, vitreous samples from tap or vitrectomy) from 100 consecutive patients presenting with acute postcataract endophthalmitis. Bacterial cultures were performed on the same ocular samples by using traditional methods (brain-heart infusion broth). RESULTS: At the time of admission, the detection rate was not significantly different between cultures a…
Working-Age Cataract Patients: Visual Results, Reading Performance, and Quality of Life with Three Diffractive Multifocal Intraocular Lenses

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 …
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…
