A new double-arc intrastromal corneal ring segment may help to improve visual outcomes and rehabilitate the physiologic optical surface by remodelling the cornea

Endothelial keratoplasty has become increasingly common in northwestern Italy, paralleling a rise in the demand for corneal surgery, researchers said.

Topography disparity can even provide a useful parameter for diagnosing the subclinical form of the disease, said David P. Piñero, PhD, and colleagues from the Medimar International Hospital, Alicante, Spain.

Corneal asphericity, OCT angiography, and balance control issues in glaucoma patients are analyzed in this industry update roundup.

In a study in mice, researchers at the University of Pittsburgh demonstrated that stem cells harvested from extracted teeth could potentially be used to restore sight.

More research required to clarify the short- and long-term effects of femtosecond laser-assisted cataract surgery (FLACS) on the corneal endothelium.

A single thermodynamic treatment can serve as an effective treatment of MGD and the beneficial effects of the treatment can last for 6 months or longer.

Researchers at the University of Reading, UK, report that they have discovered a potential way of making eye drops more effective.

Optimal resistance to in vitro keratolysis by collagenase A can be achieved by collagen crosslinking the deepithelialized anterior corneal surface for 30 minutes, according to a recently published study.

Studies with follow-up of 2 to 6 years show that corneal crosslinking for progressive keratectasia is safe and induces long-term structural changes.

Aganirsen eye drops inhibited corneal neovascularization in patients with keratitis and reduced the need for transplantation in patients who have viral keratitis and central neovascularization, according to a Phase III study of 69 patients.

Fasting significantly reduces the amount of tears produced by the eye and increases the osmolarity of the tears, according to new research.

The addition of diquafosol tetrasodium (DQS) to a regimen of artificial tears and sodium hyaluronate helped relieve the symptoms of persistent dry eye in patients who had undergone laser in situ keratomileusis (LASIK), according to recent research.

Currently, there is no treatment to promote the healing of endothelial cells, however, the extent of the corneal oedema can be controlled. In this article, Prof. Feinbaum discusses a new treatment option aimed at alleviating complications of visual loss and pain secondary to corneal oedema.

As the population is living for longer after cataract surgery, Dr Kugelberg and colleagues believed that a longer follow-up period was required to determine PCO rates in three different IOLs. Here, she discusses the highlights of this study.

The arrival of advanced therapeutic modalities for keratoconus has provided ophthalmologists with a growing menu of treatment options. The author discusses the challenge of determining which treatment is the best to use and highlights his experience with a triple procedure and a four-stage approach.

Predicting the position of an iris-fixated pIOL is important to ensure intraocular structure health is maintained. In this article, Dr Soltani Moghadam describes his recent study that found AS-OCT imaging technique to be particularly useful as a preoperative simulation technique.

Corneal anterior segment imaging has emerged as a screening tool for refractive surgery, cataract and glaucoma. In this article, the authors discuss their recent study that identified a set of normative data to correct for sources of bias in pre-surgery screening.

In this article Dr Kanellopoulos shares his opinions on AS-OCT in his practice, highlighting the clinical and diagnostic advantages he has experienced using the imaging device.

In this article, Dr Cervino discusses how his recent study examining the quality of anterior segment images obtained with posterior segment OCT devices is good enough to obtain repeatable measures of anterior segment parameters manually using external analysis software.

The CorVis ST, a new Scheimpflug-based device, has the potential to analyze ocular biomechanical properties for further research. Here, Dr Nemeth discusses his recent study analyzing the repeatability of data obtained with this new device.

Here, Dr Cadarso discusses how he targets vertical coma specifically through adaptation of the Keraring ICRS implantation technique.

Non-invasive imaging modalities, such as high-resolution anterior-segment optical coherence tomography (AS-OCT) and in-vivo confocal microscopy (IVCM) imaging, may be more sensitive to identifying and monitoring epithelial downgrowth, compared with routine light biomicroscopy in patients undergoing penetrating keratoplasty, and will perhaps replace more invasive diagnostics in these patients.

In this article, Dr Vryghem weighs up the pros and cons of visual revalidation techniques and compares the currently available techniques in a clinical setting.

Eyes with a history of herpes simplex keratitis (HSK) have significantly greater higher order aberrations (HOAs) than eyes with no past history of the disease, according to a paper.

A novel technique for performing Descemet stripping automated endothelial keratoplasty (DSAEK) consistently yields thin grafts, according to recently published research in the British Journal of Ophthalmology.

Straylight values improve over time and can be linked to the progression of corneal healing, according to a paper.

The Standard Patient Evaluation of Eye Dryness (SPEED) questionnaire is a repeatable and valid method to measure dry eye symptoms, reveals a recent paper in the journal Cornea.

Corneal collagen crosslinking (CXL) could successfully treat certain stages of keratoconus, according to a recent published paper.

NovaTears has received the CE Mark of approval for the treatment of dry eyes, according to the latest press release from Novaliq.
