[Thésaurus Mesh]Vision oculaireRésumé : More than 90% of the sensory information that we use for driving is estimated to be visual. However, there is ongoing debate regarding the extent to which different ocular conditions and types of visual impairment affect driving performance and which visual functions are most important for safe driving. My program of research has sought to address these questions using a range of experimental approaches including measures of real-world driving performance on a closed-circuit driving course and under in-traffic conditions. This article provides a current overview of how visual impairment affects driving ability and safety and also highlights the visual challenges of nighttime driving, including the visibility of vulnerable road users, based on the wider research literature, as well as providing a snapshot of some of my own studies. Emphasis is placed on those studies that are relevant to assessing a patient's visual fitness to drive, as well as providing appropriate advice regarding the impact of common visual impairments on driving ability and safety.

[Thésaurus Mesh]Troubles de la visionMots-clés : Cornée irrégulière Résumé : SIGNIFICANCE: Highly irregular cornea leads to poor vision, glare, and starbursts. Although treatment is still at the exploration stage, topography-guided Contoura surgery has excellent potential for the treatment of highly irregular corneas. PURPOSE: This case series reviews three patients (one with abnormal back elevation, one with corneal scar after fungal keratitis, and one with post–laser-assisted in situ keratomileusis central islands) treated with topography-guided Contoura surgery. CASE REPORTS: In case 1, a 19-year-old man underwent topography-guided Contoura refractive surgery in the left eye and wavefront-optimized ablation in the right eye. Post-operative topography of the right eye showed marked inferior steepening and central irregular astigmatism compared with the contralateral eye. In case 2, a 53-yearold man presented with corneal scarring on the right eye after recovering from fungal keratitis. The patient first underwent phototherapeutic keratectomy and photorefractive keratectomy to remove the scarring primarily. He then underwent Contoura to correct hyperopia, which flattened the cornea and improved his vision significantly. In case 3, a 25-year-old man presented with central steepening on topography maps after undergoing laser-assisted in situ keratomileusis. He underwent topography-guided ablation, which improved his visual acuity and normalized the cornea. CONCLUSIONS: Therapy for highly irregular corneas includes wavefront-guided surgery, conservative treatment, corneal transplantation, rigid gas-permeable lenses, and so on. In this case series, topography-guided Contoura refractive surgery provided an excellent option for reducing topographic abnormalities and improving vision. Note de contenu :

[Thésaurus Mesh]Recherche comparative sur l'efficacitéMots-clés : lentilles diffractives lentilles non diffractives Résumé : SIGNIFICANCE: The modulation transfer functions (MTFs) of two novel enhanced depth-of-focus (EDoF) intraocular lenses (IOLs) were compared with an established diffractive EDoF IOL. Such assessment, which was not described before in the literature, is of high clinical impact in lens surgery.
PURPOSE: A new kind of nondiffractive, wavefront-shaped EDoF IOLs has been introduced very recently to cope
with halos and glare known from diffractive optics. We aimed to assess the performance of two of these novel EDoF
IOLs compared with an established diffractive EDoF IOL.
METHODS: TECNIS Symfony, AcrySof IQ Vivity, and LuxSmart Crystal IOLs (22 D each) were assessed by the
OptiSpheric IOL PRO 2 imaging test bench with an ISO-2 cornea and a wavelength of 546 nm. Measurements
were carried out by TRIOPTICS GmbH. Through-frequency MTF, Strehl ratio, and U.S. Air Force targets were
evaluated. A decentration of 1 mm and a tilt of 5° as well as different apertures of 3 and 4.5 mm were applied
additionally.
RESULTS: TECNIS Symfony performed superiorly to Vivity and LuxSmart for our settings. The diffractive optics of
Symfony showed a considerable decrease in MTF and Strehl ratio when decentered. Overall, decentration had
more impact on MTF and Strehl ratio than tilt. Larger aperture led to a decreased MTF and Strehl ratio for all IOLs
tested. U.S. Air Force targets had better contrast for Symfony and for small aperture.
CONCLUSION: The novel wavefront-shaped EDoF IOLs failed to outperform the established diffractive achromatic
optics of Symfony EDoF IOL with respect to MTF and qualitative contrast function. These results apply only to the
distance viewing condition. Near vision performance will be evaluated in a future study.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

PURPOSE The purpose of this study was to investigate risk factors associated with development of clinically significant posterior capsule opacification requiring yttrium aluminum garnet (YAG) capsulotomy.
METHODS Medical records of patients (≥18 years) who underwent cataract surgery between January 1, 2011, and March 31, 2014, at Kresge Eye Institute were reviewed. Three hundred eyes requiring YAG capsulotomy up to 3 years after cataract surgery were included in the YAG capsulotomy group. Three hundred eyes not requiring YAG capsulotomy up to 3 years after cataract surgery were selected via age-matched simple randomization (control group).
RESULTS The YAG capsulotomy group included patients with younger age (65.8 ± 11.3 vs. 70.1 ± 10.6 years, P < .001), more men (42.67 vs. 34.67%, P = .04), fewer patients with hypertension (73.00 vs. 83.00%, P < .001), and more patients with hydrophilic intraocular lenses (74.67 vs. 47.00%, P < .001). Logistic regression analysis demonstrated a negative association between YAG capsulotomy and age (coefficient, −0.04; 95% confidence interval [CI], 0.95 to 0.98; P < .001) and hydrophobic intraocular lenses (coefficient, −1.50; 95% CI, 0.15 to 0.33; P < .001), and a positive association with presence of glaucoma (coefficient, 0.88; 95% CI, 1.39 to 4.17; P = .002). Elapsed time to YAG capsulotomy was sooner in patients with a history of uveitis (95% CI, 5.10 to 9.70 months; P = .02) and insertion of hydrophilic intraocular lenses (95% CI, 18.67 to 21.57 months; P < .001).
CONCLUSIONS Results of this study suggest that development of visually significant posterior capsule opacification is associated with younger age, glaucoma, and hydrophilic intraocular lenses, and it occurs earlier among those with hydrophilic intraocular lenses and a history of uveitis.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

Les ultra-violets, principalement émis par la lumière du soleil sont les radiations les plus nocives pour l'œil. Lorsque nous sommes éblouis, nous portons des verres teintés pour réduire l'entrée de la lumière dans l'œil. Dans des cas plus spécifiques d'hypersensibilité lumineuse, des verres de teinte jaune-orangés sont utilisés pour limiter spécifiquement l'entrée de lumière bleue. Les verres anti-lumière bleue que nous portons communément aujourd'hui pour nous protéger de la surexposition aux écrans et aux leds combinent cette technique et celle de la couleur du reflet résiduel réfléchit de l'anti-reflet. Cette combinaison peut filtrer jusque 50 % de la « mauvaise » lumière bleue Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
