Cataract & Refractive

Implantation of an intracorneal inlay (Kamra, AcuFocus) modified the normal structure of the corneal layer of the eye but did not cause severe complications in a recent small study.

Both toric IOLs and peripheral corneal relaxing incisions (PCRIs) reduce astigmatism, but toric IOLs do so to a greater extent as well as being more predictable, according to results of a recently published study.

For the calculation of corneal power, using a single value for a keratometric index (nk) is imprecise and may lead to significant clinical errors, warn researchers of a recent study.

One solution for presbyopes is small diameter corneal inlays and in this article Dr Ratkay-Traub discusses her study into the long-term outcomes of presbyopia treatment with a hydrogel near vision inlay.

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.

In this article, Dr Solborg Bjerrum discusses his recent study assessing whether there is an increased risk of post-op endophthalmitis in private clinics versus public hospitals.

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.

Universal use of intracameral antibiotics can nearly eliminate postoperative endophthalmitis, according to one ophthalmologist.

The microbiological spectrum in patients with post-traumatic endophthalmitis has remained unchanged over the past 14 years, with Bacillus spp. still the most commonly found infecting organism, and vancomycin remaining the drug of choice for empiric coverage of gram-positive bacteria.

The Optimis Fusion integrated laser platform from Quantel Medical has received CE Mark approval. The system is a combination of advanced selective laser trabeculoplasty photoregeneration therapy with traditional YAG photodisruption treatment for treating both cataract and glaucoma.

Corneal refractive surgery may be more successful in eyes in which the cylinder mainly originates from the anterior cornea; therefore, in candidates for refractive surgery, surgeons should carefully assess the interaction between topographic, refractive and ocular residual astigmatism (ORA) to identify those at high risk for having significant differences between subjective cylinder and topographic astigmatism.

In this article, Dr Amparo discusses the role of tear osmolarity measurements in the assessment of dry eye disease and the patient's response to therapy.

Phaco tips are an important part of the phacoemulsification tool set. Dr Bazzigaluppi performed a comparison on a traditional and newer tip to evaluate the efficiency, safety and stability differences. Here, we explore his reasons for performing this study.

In this article, Dr Akpek discusses the pros and cons of currently available options in the management of meibomian gland dysfunction.

Post-refractive surgery dry eye is an unwanted yet reoccurring problem for surgeons, according to Dr Cummings. In this article, he discusses the pre-op approach taken in his practice, which leads to a more certain diagnosis and higher patient satisfaction rates.

Four industry leaders discern what the biggest opportunities and challenges were of 2013 and what we should be excited about for the coming year.

Corneal crosslinking is a hot topic at the moment, but according to Dr Cummings, it is important to do some due diligence about the available technology.

The availability of newer presbyopia solutions such as corneal inlays has changed the landscape of presbyopia treatment and is now allowing us to offer our patients a better quality of vision.

Ophthalmologists from 76 countries discussed the latest findings in diagnostics and therapy, and also issues of promoting the next generation of young ophthalmologists.

Advancements in cataract surgery have always been surrounded by passionate debate with arguments for and against new technologies and techniques. In this article, the authors discuss their recent study in which they examined the evolution of cataract surgery and controversy surrounding it.

Nicox has launched Sjö, an advanced diagnostic panel for the early detection of Sjögren's syndrome, and has formed a partnership with the Sjögren's Syndrome Foundation to raise aware of this disease among eye care professionals.

ML7 has the potential to bring an effective, targeted therapeutic response in patients who suffer from dry eye syndromes. Preclinical trials of the eye-drop formulation of Neuroptis Biotech's ML7 product have yielded positive results, and have recently been published.

The most common indications for IOL exchange are IOL dislocation and incorrect IOL power, according to study results in press for the American Journal of Ophthalmology. Patient requests for IOL exchange due to dissatisfaction have also increased, and this is especially true for patients who achieve undesired visual acuity even without photic symptoms.

Phacoemulsification done after trabeculectomy may significantly increase the rates of bleb failure in the following 12 months, but not at 24 months, according to a recently published study.

Traditionally, corneal astigmatism in cataract patients has been addressed through corneal correction by means of corneal incisional relaxing techniques, excimer laser keratectomy and, most recently, by means of femtosecond laser astigmatic keratotomy.

In this article, the authors describe the IOL in detail and discuss a feasibility study, concluding that the concept of a multi-component IOL can help overcome any refractive problem that may arise at any time after cataract surgery.

Preliminary results suggest that the PresVIEW ScleraI Implant, a two-part clear plastic locking implant designed to provide secure placement in the eye, is safe and effective for presbyopic emmetropes and has demonstrated interesting intraocular pressure (IOP) reduction capabailities.
