The iPure IOL (Physiol), which is composed of a new hydrophobic acrylic IOL material designed to be less prone to glistening, appears to provide an optical performance and intracapsular stability similar to lenses composed of an older hydrophobic material. “Early results reveal a good optic performance compared to a gold standard acrylic IOL.

Wavefront-guided LASIK using the iDesign (Abbott Medical Optics Inc.) System can produce highly predictable refractive outcomes in eyes with myopia and myopic astigmatism, with no loss of corrected visual acuity and no loss in quality of vision, said Sarah Moussa MD, University Eye Clinic, Paracelsus Medical University, Salzburg, Austria.

Monovision with monofocal IOLs offers a viable modality for presbyopia correction in pseudophakic patients. However, what constitutes the desired refractions for pseudophakic monovision is a matter of controversy. According to Kristian Naser MD, surgeons should consider targeting -0.25 D pure sphere for the distance eye and -1.25 D pure sphere for the near eye as that strategy optimises the range of functional vision without introducing any significant downsides.

There is no “one-size-fits-all” solution for every presbyopic cataract or refractive lens exchange patient, and surgeons need to take due account of criteria such as lifestyle, occupation and expectations in guiding their choice of treatment for these patients, according to Hiroko Bissen- Miyajima MD, PhD.

A novel treatment paradigm that combines corneal parameters with refractive measurements can be used to deliver safe and effective excimer laser treatments in patients with mild or forme fruste keratoconus, according to Noel Alpins FRANZCO, FRCOphth, FACS.

The ESCS-funded PREvention of Macular EDema after cataract surgery (PREMED) study should help to provide evidence-based recommendations for clinical guidelines to prevent the occurrence of cystoid macular oedema (CME) after cataract surgery in patients with and without diabetes mellitus (DM). The PREMED study is an initiative of the University Eye Clinic Maastricht UMC, the Netherlands, under the supervision of Prof Rudy Nuijts MD, PhD.

The risk of posterior capsule (PC) rupture during irrigation and aspiration (I/A) is decreased with the use of a silicone tip instrument, a new analysis indicates. The study was conducted by ophthalmologists at the MidYorkshire Hospitals NHS Trust, UK, where in September 2011, the department switched from using a metal tip I/A instrument to a silicone tip device (CapsuleGuard, Bausch + Lomb Storz). It was reported by Atul Varma FRCOphth, MS, consultant ophthalmologist, at the XXXI ESCRS Congress in Amsterdam.

Surgeons can employ a number of surgical techniques to avoid astigmatism post-keratoplasty, with the use of femtosecond laser having many benefits in particular, the XXXVII UKISCRS Congress in Manchester heard. Sheraz Daya FRCS(Ed), FRCOphth noted that with post-keratoplasty ametropia the refractive error is primarily due to astigmatism and spherical error, saying surgeons need to consider how they can perform better corneal transplant procedures.

Results of a prospective comparative study evaluating macular thickness changes after uneventful cataract surgery indicate that further study is warranted to establish the safety of intracameral lidocaine for surgical anaesthesia. The research was conducted by ophthalmologists from Balikesir University Medical Centre, Balikesir, Turkey, and presented by Sitki Samet Ermis MD, at the XXXI ESCRS Congress in Amsterdam.

Observed changes in wavefront aberrations between near, intermediate and far vision in patients implanted with the WIOL-CF accommodative IOL (Medicem, Czech Republic) offer objective evidence of accommodation and insight about its mechanisms, said Ioannis G Pallikaris MD, PhD, at the XXXI ESCRS Congress in Amsterdam.
