There is no current proof that blocking blue wavelengths guarantees retinal protection and, couple this with the fact that blocking this form of light causes an actual loss in visual quality, Alessandro Franchini MD, suggests we concentrate our efforts on blocking UV and violet radiations instead.
The Tecnis multifocal intraocular lens (MIOL) is safe and efficacious for refractive lensectomy in hyperopia and presbyopia, according to Frank Goes, Belgium.
The Zyoptix XP (Bausch & Lomb) microkeratome achieved increased stromal bed quality when compared with both standard and zero compression Hansatome heads (Bausch & Lomb), Thomas Hammer said.
Phacoemulsification procedures consume significantly less fluid using torsional compared with longituinal ultrasound in hard cataract cases, according to Khiun Tjia of the Netherlands.
Advanced Medical Optics (AMO) announced the launch of the Tecnis CL intraocular lens (IOL) at the XXIV congress of the ESCRS.
The LADAR 6000 excimer laser with high-speed ablation (Alcon) offers excellent visual outcomes, according to Ángel López Castro of Spain, speaking at the Alcon symposium.
The age of refractive surgery has introduced new aberrations to the human eye that require a shift in how visual performance is evaluated, said Ray Applegate, MD. Mesopic low contrast acuity best quantifies vision quality; it overcomes the weaknesses of other metrics and it can predict visual function among individuals.
While smooth wavefronts are to be preferred, some abberations may be beneficial and further study is need to identify them, said Jos Rozema, MD, of University Hospital Antwerp, Belgium.
The new MICS lens (Ioltech-Zeiss) is appropriate for the correction of intermediate vision in pseudophakia, according to Carlos Verges, Jorge Cazal and Marc Menezo of the Department of Ophthalmology, Institut Universitari Dexeus, Barcelona, Spain.
It is mandatory to develop precise , reproducible and accurate methodologies to obtain objective measurements of quality of vision, namely night vision, in order to create surgical techniques that will eliminate post-refractive vision disturbances, Joachim Murta said.
The primary function of biomechanical measurements is to improve safety and doctors can readily use these metrics in clinical practice today through the use of proxies, said William J. Dupps, MD.
The ophthalmic equipment manufacturer, bon optic, has unveiled its new topographer to the ophthalmic community.
From the 9-13 September, the Excel Exhibition and conference centre in London will open its doors to more than four thousand delegates for the 24th Congress of the European Society for Cataract and Refractive Surgeons (ESCRS). This year's congress is full to the brim of symposia, courses and skills training, in addition to having one of Europe's largest ophthalmic exhibitions.
The ESCRS will be organizing a number of sightseeing tours during the meeting. The London City Tour will take in the major sights of London, including Buckingham Palace, Westminster Abbey, Harrods, Trafalgar Square, St Paul's Cathedral and much more. There will also be an opportunity to visit Windsor Castle and Hampton Court Palace, home to the British monarchy past and present.

Risk factors for secondary glaucoma in children
CCT a risk factor for glaucoma damage
Central corneal thickness (CCT) may decrease over time, particularly in eyes with primary open angle glaucoma (POAG) but this may not be related to disease progression.
The May 2005 acquisition of VISX saw AMO inherit a large installed base of refractive surgery technologies, which not only complemented its refractive IOL portfolio, but also transformed AMO into the world's leading refractive surgical company.
December 2005 witnessed the launch of Carl Zeiss Meditec's latest model for customized refractive surgery; the CRS-Master 2.1. Equipped with a new wave of design enhancements, topography-guided therapy has now been added as a new functionality mode to the system.
Wavefront analysis of the human eye is based on an optical theory that was first developed in astronomy more than 100 years ago, with roots that date back almost 400 years. Astronomers used the technology to reduce higher order aberrations (HOAs) induced by the earth's atmosphere. Recognising the potential of this analysis in ocular refractive surgery, manufacturers have recently introduced wavefront technology into several major laser systems in order to improve treatment outcomes and address HOAs within the visual system.
Early surgical intervention and adequate orthoptic therapy are important when dealing with children who have undergone cataract surgery. A pseudophakic implant represents an effective solution for the management of aphakic children; a multifocal IOL can provide additional correction, without hindering quality of vision. Here, Klaus Weber, MD provides a brief overview of the incidence, causes and management of childhood cataract, and recommends potential avenues of treatment for the visual rehabilitation of paediatric patients with aphakia.
Here, we take a closer look at Schwind's latest unveiling, the ESIRIS excimer laser with the ORK-CAM (ORK-Custom Ablation Manager) software with aspherical aberration-free profiles.
Ophthalmologists who perform refractive procedures today, often to the dismay of patients as well as the treating physicians, achieve less than optimal satisfactory results postoperatively in 5% to 25% of their patients. Residual refractive errors, overcorrection, as well as pre-existing irregular astigmatisms induced by small optical zones and/or decentred ablations are difficult to correct with standard treatments because of their irregular nature.
An FDA panel has recommended against the approval of VisionCare Ophthalmic Technology's Implantable Miniature Telescope (IMT).
It ensures faster rehabilitation of patients operated on using 22 gauge compared with conventional 2.8 mm coaxial phaco, probably because of the reduction in postoperative trauma during emulsification of the crystalline lens in a closed system with narrow incisions
The mixing and matching of refractive and diffractive multifocal intraocular lenses (MIOLs) to enhance vision in cataract patients is not a new concept. In fact, the theory was first pioneered and realised in 2000 by Uzeyir G?nenc, MD of Dokuz Eyl?l University, Izmir, Turkey, who went on to present his first set of results at the 2003 congress of the ASCRS. So why is it that, back then, nobody really paid attention to this technique? The answer is simple; the idea at that time seemed quite bizarre and was something that many surgeons would never consider performing in their own practice. Three years on and armed with five-year data, the global ophthalmic community is now starting to pay attention.
The management of paediatric glaucoma is primarily surgical. In the literature, goniotomy and trabeculotomy, despite success rates of only 40-90%, are still the initial surgical procedures of choice for most cases of primary congenital glaucoma. In the case of secondary glaucomas associated with conditions such as aphakia, aniridia, anterior segment dysgenesis and Sturge-Weber syndrome, the success rates of goniotomy or trabeculotomy are much lower.
