Wavelight has announced the receipt of two regulatory approvals for its intraocular lenses (IOLs), thus expanding its intraocular product range.

Clear corneal incisions and silicon IOLs are new risk factors in post-cataract surgery endophthalimitis, Peter Barry revealed in the first presentation of the full ESCRS endophthalmitis study results.

According to Zdenek Gregor of Moorfields Eye Hospital, London, UK, prevention of endophthalmitis will always be preferable to a cure. While the use of preoperative povidone iodine has managed to decrease the incidence of the infection, the hope is that per-operative intracameral antibiotics will further fuel a decrease in incidence of this worrying consequence of cataract surgery.

It is possible to achieve a lower rate of endophthalmitis with a single injection of cefuroxime at the conclusion of cataract surgery than by using the more traditional subconjunctival/topical regimens, according to Per Montan of the St Erik Eye Hospital, Stockholm, Sweden.

Schwind's ESIRIS and Wavelight's 400Q laser systems are equally efficacious in correcting refractive error, according to a study presented by Yannis Aslanides, MD of the Emmetropia Mediterranean Eye Clinic in Crete, Greece.

Tensioning of Schlemm's canal may reduce intraocular pressure (IOP) in non-penetrating surgical treatment of open angle glaucoma (OAG), according to the results of a study conducted by Manfred Tetz and colleagues from Germany.

Swiss firm, Ziemer Ophthalmic Systems took advantage of the ESCRS congress to reveal its femtosecond laser Da Vinci to the ophthalmic community.

Refractive lens exchange (RLE) is not reversible so doctors need to apply their surgical wisdom to identify the most appropriate cases, Jorge Alió of the Instituto Oftalmologico de Alicante, Spain said. Often indications are based on the simplicity of the procedure but that doesn't always balance well with the best patient benefit.

Selective laser trabeculoplasty (SLT) is an effective treatment for glaucoma and offers good long term outlooks, according to Madhu Nagar of the Clayton Eye Centre, UK.

The IntraLase femtosecond FS30 laser creates a more predictable and more stable flap thickness than the Hansatome XP microkeratome (Bausch & Lomb) and the IntraLase femtosecond FS2 laser, according to research conducted by Baha Toygar and colleagues from Turkey.

In most eyes, the benefits of refractive lens exchange (RLE) outweigh the risks and it can provide a large improvement in patient quality of life, David Hardten said.

Among the different IOL options for presbyopia, monofocals are probably by far the most practically used ones said Thomas Neuhann. He added that competing options must be able to beat an already high level of success and patient satisfaction.

Instability in the pressure line could explain the pumping phenomena sometimes reported during cataract surgery, according to Carlos Verges, Jorge Cazal and Cosme Lavin of the Department of Ophthalmology, Institut Universitari Dexeus, Barcelona, Spain.

According to Manfred Tetz and colleagues, Germany, dilation and tensioning of Schlemm's canal may be an effective, non-penetrating surgical method for the treatment of open angle glaucoma (OAG).

Mixing and matching diffractive and refractive multifocal lenses increases overall visual performance by enhancing range of vision, according to Angel López Castro of the Laservisión Clínica Oftalmológica in Madrid, Spain.

Selective laser trabeculoplasty (SLT) offers good long-term reductions in intraocular pressure (IOP), according to the results of a study performed by Rahul Yadav, MD and colleagues of the Mid Yorkshire Hospitals NHS Trust, Wakefield, UK.

Selective laser trabeculoplasty (SLT) should be used before alteration of treatment or trabeculectomy, according to the findings of a study conducted by Bharat Kapoor and a team of colleagues from the UK.

Great care and detailed assessment are essential for cataract extractions where another ocular surface disease (OSD) is present, Thomas Neuhann said. Diseases range from dry eye, conjuntivalisation, irregular surfaces and corneal scars.

The use of the ReSTOR intraocular lens (IOL) (Alcon) for patients requiring cataract surgery after prior laser photoablation can result in excellent outcomes if optical results fall near emmetropia, according to Samuel Masket of the USA.

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.

The Tecnis multifocal intraocular lens (MIOL) is safe and efficacious for refractive lensectomy in hyperopia and presbyopia, according to Frank Goes, Belgium.

A number of studies have been conducted and presented during a free paper session, supporting Alcon's research into its investigational AcrySof angle-supported phakic intraocular lens (IOL).

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.

An initial clinical evaluation of the new ESIRIS excimer laser with integrated, online, optical coherence pachymetry (Schwind), showed that constant corneal monitoring is an important safety feature for LASIK procedures, Kumar J. Doctor said.

LASIK patients who make complaints symptomatic of dry eye may be suffering not from dry eye but from damaged, aberrantly regenerating nerve cells, said Timo Tervo.

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.

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.

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.
