Refractive lens exchange with Acri.LISA bifocal intraocular lens implantation.
2011
PURPOSE To assess efficacy, safety, and predictability after refractive lens exchange (RLE) in patients who had bilateral implantation of an Acri.LISA 366D diffractive bifocal intraocular lens (IOL). METHODS Sixty-six eyes of 33 consecutive patients were examined after RLE who had bilateral implantation of an Acri.LISA bifocal 366D IOL. Eyes were divided into myopic and hyperopic groups. Monocular uncorrected distance visual acuity, best-corrected distance visual acuity (BCVA), uncorrected distance near visual acuity, and best distance-corrected near visual acuity (BCNVA) were recorded preoperatively and 6 months after surgery. RESULTS Efficacy indexes were 0.73 for myopic and 0.85 for hype…
Prospective study of the Acri.LISA bifocal intraocular lens
2007
To assess the visual results after bilateral implantation of the bifocal Acri.LISA 366D intraocular lens (IOL) (Acri.Tec AG).Fernández-Vega Ophthalmological Institute, Oviedo, Spain.Eighty-one patients had bilateral implantation of the distance-dominant bifocal Acri.LISA 366D IOL in a prospective study. Monocular and binocular best corrected distance visual acuity and best distance-corrected near visual acuity, binocular best distance-corrected intermediate visual acuity, and distance contrast sensitivity under photopic (85 cd/m(2)) and mesopic (5 cd/m(2)) conditions were determined.At the 3-month postoperative visit, the mean binocular best corrected distance acuity was 0.048 +/- 0.111 log…
Clear Lens Extraction with Multifocal Apodized Diffractive Intraocular Lens Implantation
2007
Purpose To assess efficacy, safety, predictability, and stability after clear lens extraction (CLE) with multifocal diffractive intraocular lens (IOL) implantation. Design Prospective, nonrandomized, masked observational case series (self-controlled). Participants Two hundred twenty-four eyes of 112 consecutive patients after CLE with bilateral AcrySof ReSTOR Natural IOL implantation. Eyes were divided into myopic (mean spherical equivalent [SE], −6.01±2.71 diopters [D]) and hyperopic (mean SE, +3.86±2.52 D) groups. Methods Monocular and binocular uncorrected distance visual acuity (VA), best-corrected distance VA, uncorrected distance near VA, and best distance-corrected near VA were recor…
Intraocular pressure in samples of elderly Finnish and Swedish men and women.
1994
Abstract Intraocular pressure was measured in 231 systematically sampled 75-year-old men and women in Goteborg, Sweden and in 284 75-year-old and 201 80-year-old residents in Jyvaskyla, Finland as part of a comparative study on functional capacity and health, NORA 75 (Nordic Research on Ageing). After excluding the cases reporting glaucoma in their medical history or using drugs for glaucoma treatment there were no significant differences in the distributions of intraocular pressure between the men (mean intraocular pressure in the right eye 15.1 mmHg, left eye 15.0 mmHg) and women (mean intraocular pressure in the right eye 15.5 mmHg, left eye 15.8 mmHg) in Goteborg. In Jyvaskyla the 75-ye…
Retinal light sensitivity of the central visual field among 70- to 81-year-old men and women.
2009
Retinal light sensitivity of the central visual field (0-30 degrees), visual acuity, intraocular pressure and pupillary size were screened in 42 men and 42 women aged 70 to 81 years. The subjects were randomly selected from the population register. After excluding the diagnosed glaucoma cases, the men had better visual field light sensitivity values than the women. They also had lower intraocular pressure and a wider pupillary diameter than the women, whereas there were no differences in visual acuity between the sexes. When the effect of pupillary size was controlled the differences in visual field light sensitivity values between men and women became non-significant. Among these elderly p…
Sulcus implantation of a single-piece foldable acrylic intraocular lens after posterior capsular rupture in cataract surgery.
2012
Purpose. To evaluate the safety of a foldable acrylic single-piece intraocular lens (IOL) in cases of complicated cataract surgery and sulcus implantation. The setting was University and private anterior segment surgery practices. Methods. In this observational case series study, 13 eyes of 13 patients were included after complicated phacoemulsification with extensive posterior capsule rupture with or without vitreous loss. A foldable acrylic single-piece IOL (Rayner Superflex 620H; Rayner Intraocular Lenses Limited, Hove, East Sussex, UK) was implanted in the ciliary sulcus in each eye. Postoperative follow-up included best-corrected visual acuity, anterior segment biomicroscopy, IOL centr…
Cornea in acromegalic patients as a possible target of growth hormone action.
2010
Background: GH exerts its effects on many organs and the eye also seems to be a target site, although few authors have investigated the corneal thickness in patients with acromegaly. Aim: To perform a detailed ophthalmological evaluation in acromegalic patients, in relation to disease activity. Material and methods: Twenty-eight acromegalic patients (11 males, 17 females) and 22 voluntary healthy subjects underwent complete metabolic and ophthalmological evaluation, including retinal thickness (RT), central corneal thickness (CCT), and intraocular pressure values (IOP). Results: Significantly greater CCT values were found in all acromegalic patients in comparison with controls (567 vs 528.5…
Vascular risk factors in glaucoma: The results of a national survey
2007
Background The role of vascular risk factors in glaucoma is still being debated. To assess the importance of vascular risk factors in patients with primary open-angle glaucoma (POAG), data from the medical history of 2,879 POAG patients and 973 age-matched controls were collected and analyzed. Methods Design: observational survey. Setting: 35 Italian academic centers. Study population: POAG patients and age-matched controls. In order to reduce bias consecutive patients were included. Observation procedures: data concerning vascular risk factors were collected for all patients with a detailed questionnaire. A complete ophthalmological examination with assessment of intraocular pressure (IOP)…
Deep sclerectomy versus punch trabeculectomy with or without phacoemulsification: a randomized clinical trial.
2004
Purpose: To compare the efficacy of non-penetrating deep sclerectomy without implant with Crozafon-De Laage punch trabeculectomy, and to evaluate the effect of simultaneous temporal approach phacoemulsification on both techniques. Patients and Methods: Setting: Department of Ophthalmology of the University of Palermo. Design: Prospective randomized clinical trial. Patients and intervention procedures: Sixty-five patients (65 eyes) with primary open angle glaucoma (POAG) or pseudoexfoliative glaucoma (PEXG): 32 eyes underwent non-penetrating deep sclerectomy (NPDS), 17 as single procedure and 15 combined with phacoemulsification (phaco- NPDS), and 33 eyes underwent punch trabeculectomy (PT),…
Deep sclerectomy versus punch trabeculectomy: effect of low-dosage mitomycin C.
2004
<i>Purpose:</i> To compare IOP behavior after deep sclerectomy (DS) and trabeculectomy with the Crozafon-De Laage Punch (TP), using low-dosage intraoperative mitomycin C (MMC) in both techniques. <i>Methods:</i> The study was a prospective randomized clinical trial. All patients met inclusion and exclusion criteria, and were scheduled for glaucoma surgery. Forty patients were randomized to undergo either a nonpenetrating DS with MMC (DSMMC) (19 eyes) or a TP with MMC (TPMMC) (21 eyes). Postoperative examinations were performed at the 1st day, the 1st, 2nd and 3rd weeks and the 1st, 3rd, 6th, 9th and 12th months. Postoperative complications, number of antiglaucoma med…
