Corneal thickness was measured on awakening in both eyes of ten subjects who slept with a silicone elastomer lens in one eye only. The mean corneal edema level with the silicone lens after eight hours of sleep was 2.0 +/- 2.0% and was significantly lower (p less than 0.01) than the level in the eye
OBJECTIVE
To assess the medium-term efficacy and safety of treating nucleus and intraocular lens (IOL) dislocation with pars plana vitrectomy (PPV) combined with iris-claw IOL implantation.
METHODS
Department of Ophthalmology, University of Lyon 1 Claude Bernard, Lyon, France.
METHODS
Retrospective
In previous experiments, we found that a high-water-content hydroxyethyl methacrylate (Permalens) hydrogel implant was not only well tolerated within the rabbit corneal stroma but also would successfully alter the anterior radius of curvature, and thus the refractive state, of the rabbit eye. The
To compare the efficacy and safety of 2 operation methods for late in-the-bag intraocular lens (IOL) dislocation.
Prospective, randomized, parallel-group surgical trial.
Patients referred to Oslo University Hospital (tertiary referral center).
We randomly assigned 104 patients (104 eyes) either to
Macular edema has been observed frequently in man after cataract extraction, but pathogenic mechanisms remain unclear. Seven eyes of four young adult rhesus monkeys underwent lens extraction. The retinas and maculae of these eyes were examined by ophthalmoscopy fundus photography, fluorescein
The authors implanted intraocular lenses (IOL) in 780 eyes and considered complications of this surgery, dividing the complications into intraoperative and postoperative, the latter early and late. The most frequent intraoperative complications were: hyphema, vitreous injury, pupil deformation with
We compared the incidence of angiographic cystoid macular edema (CME) in eyes with ultraviolet (UV)-absorbing intraocular lenses (IOLs) with that in eyes with non-UV-absorbing IOLs. Fifty-five bilateral pseudophakic patients received a UV-absorbing IOL in one eye and a non-UV-absorbing IOL in the
CONCLUSIONS
The present study with small-diameter scleral lenses (SLs) revealed that post-lens tear thickness (PoLTT) was significantly associated with post-lens tear mixing, but not with central corneal edema, after short-term SL wear.
OBJECTIVE
The aim of this study was to investigate the
BACKGROUND
Posterior capsule opacification (PCO) after implantation of a multifocal intraocular lens (MIOL) reduces the visual acuity (VAF) for the far, as well as for the near (VAN). There is no report on results and techniques for Nd:YAG capsulotomy in the presence of PCO after MIOL
Introduction: To compare the safety and efficacy of the Therapeutic Hyper-CL™ lens versus a standard bandage contact lens (PureVision B&L) for chronic corneal edema.
Methods:
One hundred twenty-seven consecutively implanted Surgidev Style 10 Leiske Lenses were evaluated. Average time of follow-up was 41.3 months. Although final acuity of 20/40 or better was achieved in 93% of patients, the surgical reintervention rate was 14%. Penetrating keratoplasty was required in
The purpose of this 3-year prospective study is to compare high school-aged subjects, randomized into wearing soft contact lenses and spectacles, in terms of ocular health, refractive status, and self-esteem. This report focuses on ocular response to the lens care systems used through the first 18
OBJECTIVE
To evaluate the safety of scleral-lens designs, we model and clinically assess central corneal edema induced by scleral-lens wear for healthy subjects.
METHODS
Central corneal swelling during scleral-lens wear is measured using optical coherence tomography (OCT). Transport resistances are
We reviewed 224 cases that had undergone secondary lens implantation. Cystoid macular edema occurred in 16 (7.1%) cases; edema was transient in 14 (6.3%) cases and permanent in two (0.8%) cases. Three factors seem to affect the incidence of CME: time lapse between cataract extraction and lens
OBJECTIVE
To analyse results of secondary intraocular lens implantation in aphakic eyes.
METHODS
Sixty five eyes of 63 patients (23 females and 40 males) had secondary intraocular lens (IOL) implantation, from December 1996 to April 1997. Follow-up was from 1 to 21 months. An anterior chamber lens
