An artificial vision device (MyEye, OrCam) has helped a blind veteran regain his independence, according to the charity Scottish War Blinded.

Trabecular bypass procedures have become a viable option for glaucoma treatment. The Kahook Dual Blade (KDB) facilitates ab interno trabeculectomy by employing a single-use, micro-engineered excision blade that makes precise parallel incisions in the trabecular meshwork and inner wall of the Schlemm’s canal to enhance aqueous outflow. A recent study highlights the effectiveness of its application.

Cataract surgery increases the risk of diabetic macular oedema (DMO), medical records from the United Kingdom suggest. An analysis of 4,850 eyes showed that the rate of DMO requiring treatment spiked about 4 months after the surgery.

A low dose of ranibizumab (Lucentis, Genentech/Roche) works well as a treatment for retinopathy of prematurity (ROP), researchers say.

According to the latest data by the World Health Organization, there are approximately 36 million blind people in the world, and the numbers keep growing due to increasing population sizes in developing countries and rising life expectancies in developed nations.

During the XXXV Congress of the ESCRS, an international panel of expert FLACS users gathered to share their research and insights, and to learn from the experiences of their colleagues.

The first human clinical trial to preliminarily evaluate the safety and efficacy of cellular therapy with mesenchymal stem cells for the corneal stroma has shown promise.

Automated capsulotomy is a new option that surgeons can choose for patients with opaque corneas, as well as when performing an open sky rhexis during the triple procedure and during surgery that requires the use of premium or multifocal lenses.

In a world of mass production and high technology, an ocularist in Nottingham, United Kingdom, has inspired followers around the world with his high-touch approach to hand-crafting prosthetic eyes as portrayed in a couple of YouTube videos.

Optical coherence tomography angiography (OCTA) is a new imaging technique that has the potential to move rapidly into routine clinical practice. OCTA comprises different OCT-based technologies, which enable the non-invasive assessment of retinal perfusion, based on red blood cell movement in the optic nerve head, the peripapillary and the macular retina.

It is important with corneal angiography to remember that every patient is different so your technique might very slightly from patient to patient.

Research shows that enhancement rates after LASIK range from approximately 7.8% to 20%, with regression of approximately 1 diopter after 10 years.

Use of a novel semi-fluorinated alkane drug delivery technology as a vehicle to deliver cannabinoids to the ocular surface reached target tissues without systemic side effects in preclinical studies.

Corneal epithelial thickness mapping may become an easy and objective tool in the diagnosis of biomechanically unstable corneas and perhaps a multitude of anterior segment disorders.

As another year comes to an end, five members of Ophthalmology Times Europe’s Editorial Advisory Board reflect and share their perspectives on the exciting opportunities that lie ahead for ophthalmologists in 2018, whilst also considering the potential challenges.

A combination of a topical corticosteroid and a nonsteroidal anti-inflammatory drug (NSAID) is more effective than either one alone in reducing the risk of cystoid macular oedema (CME) after cataract surgery in nondiabetic patients, researchers say.

Children in Tel Aviv have been treated with nightly atropine drops, significantly slowing the progression of myopia.

Long-term observation of SMILE reveals high stability at various degrees of correction of myopia. This allows surgeons who apply this method of treatment to give patients a long-term prognosis.

After spending a few months testing for dry eye and treating the tear film before doing preoperative measurements, the re-treatment rate dropped from 11% to 3%.

A multidiagnostic device is able to provide consistent measurements of refraction and ocular aberrations in healthy eyes. The consistency of refractive measurements is not dependent on the magnitude of the refractive error, with the same precision ability for moderate to high myopia and for hyperopia.

Micropulse transscleral cyclophotocoagulation utilises a different delivery modality than its predecessor, continuous-wave laser cycloablation, to produce a biological reaction without the lethal effects caused by thermal buildup.

During the past two decades, an incredible number of imaging technologies have been developed for eye diseases, both for diagnosis and follow-up.

Roughly 300 million people are visually impaired-38 million of whom are blind and most of whom live in so-called developing countries. However, there are many institutions with specific campaigns aimed at eliminating preventable blindness.

One source of error in IOL power calculation is the use of the classical keratometric approach for the characterisation of the corneal optics. This approach is based on the assumption of only one corneal surface and a fictitious index of refraction (keratometric index, nk) for obtaining an estimation of the corneal power (Pk).

Every ophthalmologist requires precise surgical tools with which he or she can perform surgery safely and accurately in order to ensure optimal outcomes. The availability of high-quality microsurgical instruments has increased over the past decade with manufacturers continually modifying and optimising existing instruments.

The European Commission has granted marketing authorisation for cenegermin eye drops (Oxervate, Dompé) for the treatment of moderate to severe neurotrophic keratitis.

A three-day exhibition that shows how people with visual impairments can appreciate a wide range of art forms was unveiled at the Science Museum on 8th August 2017.

Today, a visit to the commercial exhibitions of major meetings is a real show, with companies’ booths offering amazing high-tech devices that promise to address the specific needs we have in our practices. Although such technology impresses us, we seldom receive information on the evidence-based data surrounding its effectiveness, its cost-benefit analysis and the potential for obsolescence.

Adding objective point-of-care dry eye diagnostics to your practice has deep, measurable effects, including more accurate and consistent IOL power calculations.

High-intensity focused ultrasound cyclocoagulation is safe and effective in most refractory glaucomatous eyes. Complete success was achieved in 80% (24/30) of treated eyes that had undergone the maximum of three procedures.
