Cataract surgery linked to changes in choroidal thickness, study finds

Cataract surgery was associated with changes in choroidal thickness, with axial length and IOP being critical in evaluating those changes, according to a study. “The choroid may be involved in the pathogenesis of various ocular diseases,” the study authors said. “It has been suggested that cataract surgery is associated with the onset of AMD.” The prospective study included 100 eyes of 100 patients with a mean age of 72.5 years and no other ocular disease who underwent cataract surgery. A control group included 20 eyes of 20 age-matched subjects.

Alcon’s annual operating income falls 16%

Operating income for Alcon in 2013 was $1.2 billion, a decline of 16% over the previous year, according to a press release from Novartis. The decline was attributed to integration and restructuring costs and was partially offset by sales growth — 3% over the previous year — and productivity gains. The Alcon surgical franchise increased by 4% in 2013 over 2012. This was driven by procedure growth, market share gains and demand for LenSx and Centurion equipment.

Cross-linking round table, part 2: Epi-on vs. epi-off and measures of success

At the 2013 European Society of Cataract and Refractive Surgeons meeting, Ocular Surgery News convened a round table of international experts to discuss the current state of corneal cross-linking. The second part of that wide-ranging discussion, moderated by Roy S. Rubinfeld, MD, is featured in this issue of OSN. Roy S. Rubinfeld, MD: Let’s talk about epi-on vs. epi-off in terms of safety. At this conference, there are numerous abstracts and presentations showing some proprietary new epi-on cross-linking techniques to have efficacy similar to older epi-off techniques, but when there (Read more...)

Pathologic myopia associated with higher OSDI scores, lower TBUT

Patients with pathologic myopia experienced more severe Ocular Surface Disease Index symptoms and faster tear film breakup times than controls, according to a study. The study compared 45 patients with pathologic myopia with 44 healthy individuals. Researchers defined pathologic myopia as spherical equivalent (SE) refractive errors greater than 6 D and axial globe length (AL) of more than 26.5 mm. No statistically significant difference between groups was seen in corneal staining or in Schirmer’s 1 test scores, both with and without anesthesia, but SE, keratometry, AL, tear breakup time (TBUT) (Read more...)

Multivitamin use markedly reduces cataract risk in men aged 50 and older

Long-term multivitamin use decreased the risk of cataract in middle-aged men but had an insignificant impact on age-related macular degeneration, according to a large study. “Given that an estimated 10 million adults in the United States have impaired vision due to cataract, even a modest reduction in risk of cataract has potential to improve public health outcomes,” the study authors said.
