During accommodation, changes in lens thickness are mainly caused by deformation of the nucleus. In older, non-accommodating lenses, the deformations occur predominantly in the equatorial region and do not affect the central curvatures of the lens, according to a report published online ahead of print by Acta Ophthalmologica.
There have always been good arguments for surface ablation, but in most cases I have personally preferred LASIK. Yet every year I find myself performing more and more surface ablation cases and I am not alone in this.

Dynamic contour tonometry (DCT) provides a more accurate measure of glaucomatous visual field loss and intraocular pressure (IOP) when compared with Goldmann applanation tonometry (GAT), according to a study published in the December 2007 issue of the Journal of Glaucoma.
Have a closer look at some of the multifocal IOLs available in Europe.
It is more cost-effective to perform routine tonometry in all initial ophthalmic patients than in none at all or in just high-risk glaucoma patients, according to a paper published in the March 2008 issue of Eye.
A protein, called Robo4, has been identified which appears to play an important role in the development of stable, working blood vessels.
The incidence of endophthalmitis following injections of anti-VEGF drugs is lower when the injections are given in an office setting than the rates reported from clinical trials, which require a more extensive pre-injection regimen.
According to a presentation at the All India Ophthalmological Society meeting, when used appropriately, bevacizumab can produce remarkable results in children with severe retinopathy of prematurity (ROP).
Intraocular lenses (IOL) made from polymethylmethacrylate (PMMA) may be associated with an increased risk of postoperative endophthalmitis.
The first results of an ongoing multicentre study in France suggest that a new diffractive intraocular lens (IOL), Diffractiva-s (HumanOptics), offers good visual results.
Cataract referrals made by optometrists are more likely to include better information regarding vision loss than referrals made by general practitioners .
OTE has tapped into the minds of some great European surgeons, to see what they felt were the events that shaped the IOL industry in 2007.
Patients with newborn primary congenital glaucoma have a better chance of successful surgery if glaucoma drainage device implantations or trabeculectomies are performed instead of goniosurgery.
American and European physicians prefer to treat glaucoma with prostaglandin monotherapy, most commonly latanoprost.
Erbium YAG-laser-assisted deep sclerectomy (DS) offers greatly simplified dissection and better long-term intraocular pressure (IOP) control compared with conventional DS.
The size and binding characteristics of proteins are likely to influence their ability to penetrate the eye from the periocular space, but in general, proteins as large as 50-75 kDa penetrate well into the choroid but not into the retina.
Reichert has received 510k clearance from the FDA to market the Reichert-Optopol Spectral Optical Coherence Tomographer (SOCT) in the US.
Sirion Therapeutics has entered into an exclusive agreement with Bridge Pharma for the worldwide rights to develop and market topical ophthalmic formulations containing Bridge's proprietary anti-inflammatory agent norketotifen.
Preoperative tear volume may affect recovery of the ocular surface after LASIK and could increase the risk for chronic dry eye.
Topical levofloxacin penetrates better than ofloxcin or ciprofloxacin into the aqueous of eyes with functioning filtering blebs.
Six-month data for myopia treatments with the SCHWIND AMARIS laser show that it is effective and patient friendly.
Clinicians have an array of techniques and devices available to them for assessing progression of glaucoma, and more are under development. Such tools rely on either subjective or objective measurements, with the latter generally providing more reliable results. Frequent, long-term follow-up with one or more of those approaches will increase the likelihood of detecting progression early.
Alcon has announced positive efficacy and safety results from its second controlled proof of concept clinical study of anecortave acetate administered as an anterior juxtascleral depot in the sub-Tenon's space to reduce intraocular pressure (IOP) in patients with open-angle glaucoma.
