<h3>Background:</h3> A new commercially available optical low coherence reflectometry device (Lenstar, Haag-Streit or Allegro Biograph, Wavelight) provides high-resolution non-contact measurements of ocular biometry. The study evaluates the validity and repeatability these compared with current clinical instrumentation. <h3>Method:</h3> Measurements were taken LenStar IOLMaster on 112 patients aged 41–96 years listed for cataract surgery. subgroup 21 also had A-scan applanation...
<h3>Aim</h3> To assess the accuracy and reproducibility of biometry undertaken with Aladdin (Topcon, Tokyo, Japan) in comparison current gold standard device, IOLMaster 500 (Zeiss, Jena, Germany). <h3>Setting</h3> University Eye Clinic, Birmingham, UK Refractive Surgery Centre, Kiel, Germany. <h3>Methods</h3> The right eye 75 patients cataracts 22 healthy participants were assessed using two devices. Measurements axial length (AL), anterior chamber depth (ACD) keratometry (K) random order by...
In Brief Purpose: To compare corneal thickness measurements using Orbscan II (OII) and ultrasonic (US) pachymetry in normal keratoconic eyes. Setting: Eye Department, Heartlands Solihull NHS Trust, Birmingham, United Kingdom. Methods: Central (CCT) was measured by means of OII US 1 eye 72 subjects 36 keratoconus patients. The apical (ACT) patients also evaluated each method. mean the difference, standard deviation (SD), 95% limits agreement (LoA = ± 2 SD), with without applying default...
Purpose. To compare visual function with the Bausch & Lomb PureVision multifocal contact lens to monovision single vision lenses. Methods. Twenty presbyopic subjects were fitted either or After a 1-month trial, following assessments of made: (a) distance, intermediate, and near acuity (VA); (b) reading ability; (c) distance contrast sensitivity (CSF); (d) range clear vision; (e) stereoacuity; (f) subjective evaluation ability standardized questionnaire. Subjects then refitted alternative...
Purpose.: To determine the most appropriate analysis technique for differentiation of multifocal intraocular lens (MIOL) designs by using defocus curve assessment visual capability. Methods.: Four groups 15 subjects were implanted bilaterally with either monofocal lenses, refractive MIOLs, diffractive or a combination and MIOLs. Defocus curves between −5.0 D +1.5 evaluated an absolute relative depth-of-focus method, direct comparison new "area-of-focus" metric. The results correlated...
To develop a standardized questionnaire of near visual function and satisfaction to complement evaluations presbyopic corrections.Eye Clinic, School Life Health Sciences, Aston University, Midland Eye Institute Solihull Hospital, Birmingham, United Kingdom.Questionnaire development.A preliminary 26-item previously used items was completed by patients with monofocal intraocular lenses (IOLs), multifocal IOLs, accommodating contact lenses, or varifocal spectacles. Rasch analysis for item...
<h3>Background/aims</h3> To investigate the efficacy and safety of MGDRx EyeBag (The Eyebag Company, Halifax, UK) eyelid warming device. <h3>Methods</h3> Twenty-five patients with confirmed meibomian gland dysfunction (MGD)-related evaporative dry eye were enrolled into a randomised, single masked, contralateral clinical trial. Test eyes received heated device; control non-heated device for 5 min twice day 2 weeks. Efficacy (ocular symptomology, non-invasive break-up time, lipid layer...
To evaluate the effect of reducing number visual acuity measurements made in a defocus curve on quality data quantified.Midland Eye, Solihull, United Kingdom.Evaluation technique.Defocus curves were constructed by measuring distance logMAR letter chart, randomizing test letters between lens presentations. The powers evaluated ranged +1.50 diopters (D) and -5.00 D 0.50 steps, which also presented randomized order. Defocus measured binocularly with Tecnis diffractive, Rezoom refractive, Lentis...
Purpose: To determine whether myopic ablation by excimer laser photorefractive keratectomy (PRK) affects only the anterior curvature of cornea or changes also occur in posterior corneal curvature. Setting: Department Optometry and Neuroscience, UMIST, Optimax Laser Eye Clinic, Manchester, United Kingdom. Methods: Sixteen patients who presented for correction myopia 1 eye PRK were followed 3 months. Only newly presenting recruited, untreated eyes used as controls. The examined at initial...
To determine whether letter sequences and/or lens-presentation order should be randomized when measuring defocus curves and to assess the most appropriate criterion for calculating subjective amplitude of accommodation (AoA) from curves.Eye Clinic, School Life & Health Sciences, Aston University, Birmingham, United Kingdom.Defocus (from +3.00 diopters [D] -3.00 D in 0.50 steps) 6 possible combinations or nonrandomized were measured a random 20 presbyopic subjects. Subjective AoA was...
To better understand the phenomenon of dysphotopsia in patients implanted with multifocal intraocular lenses (IOLs).Forty-five (aged 61.8±8.9 years) bilaterally Tecnis ZM900 (diffractive multifocal), Lentis Mplus MF30 (segmented refractive multifocal) or Softec-1 (monofocal) IOLs (each n=15) 4-6 months previously and who had achieved a good surgical outcome were examined. Each reported their symptoms subjectively, identified its form (EyeVisPod illustrations), quantified retinal straylight...
