Randomized controlled clinical trial to evaluate different intraocular lenses for the surgical compensation of low to moderate-to-high regular corneal astigmatism during cataract surgery.

Purpose: To evaluate vector analysis, rotational stability, and visual outcomes after implantation of toric IOLs with low (<2.25 diopter [D]) toric values (Acrysof IQ SN6AT3 or SN6AT4) and moderate-to-high toric (3.00 D to 6.

Intraindividual aqueous flare comparison after implantation of hydrophobic intraocular lenses with or without a heparin-coated surface.

Purpose: To assess the efficacy of a heparin-surface-modified (HSM) hydrophobic acrylic intraocular lens (IOL) (EC-1YH PAL) and the same IOL without heparin coating (EC-1Y-PAL) by the flare and cell intensity in the anterior chamber after uneventful cataract surgery.

Setting: Department of Ophthalmology, Paracelsus Medical University Salzburg, Austria.

Design: Comparative case series.

Reliability of automatic biometric iris recognition after phacoemulsification or drug-induced pupil dilation.

Purpose: To investigate the reliability of a biometric iris recognition system for personal authentication after cataract surgery or iatrogenic pupil dilation.

Methods: This was a prospective, nonrandomized, single-center, cohort study for evaluating the performance of an iris recognition system 2-24 hours after phacoemulsification and intraocular lens implantation (group 1) and before and after iatrogenic pupil dilation (group 2).

Results: Of the 173 eyes that could be enrolled before cataract surgery, 164 (94.

The effect of steroids in combination with optic nerve decompression surgery in traumatic optic neuropathy.

Objectives/hypothesis: Traumatic optic neuropathy (TON) is an important cause of severe visual impairment following blunt or penetrating head trauma. Treatment options include steroids, decompression, or both. Studies have failed to show a clear benefit for either steroids or surgery or a combined therapy.

Profiles of intraocular pressure in human donor eyes during femtosecond laser procedures--a comparative study.

Purpose: To compare four different femtosecond laser devices (IntraLase FS, Zeiss VisuMAX, and Ziemer Femto LDV, and a prototype Schwind SmartTech Nanolaser) in human donor eyes with regard to their effects on IOP during femtosecond laser flap cutting. In order to get cuts parallel to the corneal surface, the cornea has to be forced into a defined shape and current femtosecond laser devices either use a flat or a curved patient interface design to achieve applanation.

Methods: IOP was measured in enucleated eyeballs (n = 46) not suitable for keratoplasty by direct cannulation of the vitreous body.

Bilateral reading performance of 4 multifocal intraocular lens models and a monofocal intraocular lens under bright lighting conditions.

Purpose: To compare changes in reading performance parameters after implantation of 4 multifocal intraocular lens (IOL) models and a monofocal IOL.

Setting: Department of Ophthalmology, Paracelsus Medical University, Salzburg, Austria.

Design: Prospective randomized controlled clinical trial.

Reading performance and patient satisfaction after corneal inlay implantation for presbyopia correction: two-year follow-up.

Purpose: To evaluate change in reading performance parameters after monocular Kamra corneal inlay implantation for the surgical correction of presbyopia.

Setting: University surgical outpatient center.

Design: Prospective interventional case series.

Iris color and visual functions.

Background: The aim of this study was to evaluate if iris color is associated with differences in visual functions such as intraocular straylight (IOSL), contrast sensitivity (CS), or best-corrected visual acuity (BCVA).

Methods: In this retrospective cohort study, which is a subgroup analysis of a large prospective trial about visual impairments in European car drivers, we included 853 persons between 20 and 80 years of age and without a history of ocular surgery or any eye disease including cataract. Subjects participated in an ophthalmological examination, grading of lens opacity, and the measurement of visual functions such as IOSL, CS, and BCVA.

Cataract and pseudophakia in elderly European drivers.

Purpose: To evaluate the prevalence and association of different types and severities of cataract or pseudophakia with visual impairments in older European drivers.

Methods: In this prospective European multicenter study, 2211 active drivers, 45 years of age and older, participated in an ophthalmologic examination, the measurement of visual functions, and were asked to fill in the NEI-VFQ-25 and another questionnaire about driving habits, driving difficulties, and self-reported accidents.

Results: Prevalence of moderate and severe forms of cataract in an active driving population is lower than that in the general population, but could be found in both eyes in 20% (95% confidence interval [CI] 16%-25%) and 17% (95% CI:13%-21%) of subjects 75 years of age and older.

Association of lens opacities, intraocular straylight, contrast sensitivity and visual acuity in European drivers.

Purpose: To study the relationship between lens opacity and intraocular straylight, visual acuity and contrast sensitivity.

Methods: We investigated 2422 drivers in five clinics in different European Union (EU) member states aged between 20 and 89 years as part of a European study into the prevalence of visual function disorders in drivers. We measured visual acuity [Early Treatment Diabetic Retinopathy Study (ETDRS) chart], contrast sensitivity (Pelli-Robson chart) and intraocular straylight (computerized straylight meter).

Straylight effects with aging and lens extraction.

Purpose: To assess possible gains and losses in straylight values among the population to consider straylight as added benefit of lens extraction.

Design: In this cross-sectional design, data from a multicenter study on visual function in automobile drivers were analyzed.

Methods: On both eyes of 2,422 subjects, visual acuity (logarithm of the minimum angle of resolution [logMAR] in steps of 0.
