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.

Safety, with respect to loss of best spectacle-corrected visual acuity, records better results for phakic IOL implantation than for LASIK with higher corrections

Combined surgical management of coexisting cataract and glaucoma has recently gained popularity because of the several advantages that it presents. These advantages include, decreased risk, easier management of early and long-term postoperative intraocular pressure (IOP) and performing just one surgical procedure to manage both problems.

The development of presbyopia in hyperopic people aged between 45 and 65 is a serious refractive problem that, until recently, has had no practical solution. Individuals in this category are not usually considered to be "patients" but, nevertheless, face real problems with their everyday near and distance sight. We call this problem "hyperopic presbyopia".

This month we are celebrating our first birthday. This time last year we launched the first issue of Ophthalmology Times Europe. I cannot believe it's come round so quickly. Although, when I reflect on how much has been achieved in such a short space of time, I suppose it's surprising that it has only been a year.

Researchers from the US based Centers for Disease Control and Prevention (CDC) have released a report explaining the causes behind the well-publicised dramatic rise of fungal eye infections among Americans.

The high incidence of neurodegenerative retinal diseases that lead to visual impairment and blindness has given rise to new technological and biological advances in the field of ophthalmology. Electronic retinal prostheses are among the most eagerly anticipated, yet complex devices to be developed. The expertise of retinal specialists, surgeons and engineers has been combined to thoroughly research the effect of electrical stimulation on retinal neurons, to develop micro-electronic chips, investigate new encapsulation methods that are bio-compatible and to develop methods of powering the subretinal devices.

80% of Tecnis patients and 85% of ReSTOR patients were very happy with all aspects of their vision, with the majority of patients in both groups deciding not to return to glasses, even for intermediate vision

All the news from the XXIV Congress of the European Society of Cataract and Refractive Surgery, held September 9–13 2006 in London, UK.

Microincision cataract surgery (MICS), hailed to be the next big development in cataract surgery, has not had the expected impact on surgeon's practice, David Leaming revealed, whilst detailing the results of his most recent survey on cataract surgery practice in Europe and the US.

Bausch & Lomb has introduced a stable chamber tubing system, as a part of the new micro incision vacuum pack, to its Millennium Micro Incision Cataract Surgery (MICS) platform.

The new *Acri.Lisa (*Acri.Tec) bifocal, acrylic IOL provides very good distance and near visual acuity and sufficient intermediate visual acuity, said Ulrich Mester. Pseudoaccommodation range is 5.5 D and it also offers improved contrast sensitivity. He noted, however, that halos are still present with the lens.

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

According to Oliver Findl, it is becoming increasingly important to use a wider variety of parameters to assess visual quality after cataract surgery in order to gain a better understanding of patient's day-to-day experiences.

Levofloxacin 0.5% eye drops should be the first choice for antibacterial prophylaxis and treatment, according to Professor P. Asbell of the Mount Sinai School of Medicine, USA.

The use of foldable intraocular lenses (IOLs) in cataract surgery is a trend that is continuing to rise across Europe, according to Mats Lundstrom speaking at the Outcomes of Cataract and Refractive Surgery symposium.

A large survey has recently been piloted in the UK to demonstrate the use and benefits of electronic data collection with respect to rapidly monitoring the access, delivery and outcome of cataract surgery in the UK's National Health Service (NHS) and to update benchmark standards for these parameters of care.

According to Alessandro Franchini, it is insufficient to design an aspheric lens that maintains a certain degree of spherical aberration simply to achieve a degree of pseudo-accommodation.

The carpenter's rule is measure twice, cut once. The wavefront aberrometry rule should be measure hundreds of times, then analysed, and then cut once, Dr Robert Iskander said.

According to Omid Kermani from the Augenabteilung der PAN-Klinik am Neumarkt, Köln, Germany, and colleagues, the implantation of a foldable toric intraocular lens (IOL) is a safe and predictable procedure for the correction of high pre-existing corneal astigmatism in cataract surgery.

According to Alaa El Danasoury and colleagues, Toric ICL (TICL; STAAR Surgical) implantation is safe, effective and predictable in its correction of compound myopic astigmatism.

Although image quality has a clear influence on visual acuity, it does not account for all the individual variability of other factors that must be involved including, measurement errors, or wavefront, optical or neural factors, Raymond Applegate said.

Howard Fine, MD, speaking at the ISRS/AAO symposium, believes that the answer to correcting presbyopia lies in accommodating lenses rather than multifocal intraocular lenses (IOLs).

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.

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.

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.

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.

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.
