Cataract & Refractive

There is a strong link between alpha-blocking medications and floppy iris.

Clear lens exchange with implantation of a trifocal IOL is the best solution.

OCT-based biometers like the ARGOS allow for accurate measurement of very dense lenses in cataractous patients.

A new method for predicting the behaviour of multifocal IOLs has been developed. This methodology could be very useful for ophthalmologists, enabling them to know the potential effect of the implantation of an IOL in any type of eye prior to implantation.

The management of astigmatism can be accomplished during cataract surgery. Employing femtosecond lasers improves the accuracy, safety and predictability of arcuate incisions, as well as the alignment of toric IOL placement.

Professor Gerd U. Auffarth and collegues have found that ophthalmic viscoelastic devices that combine both dispersive and cohesive properties, so that they can be used in sequence and at the appropriate phases of cataract surgery, can result in decreased complications, low adverse events, improved visibility and good space management.

The second-generation Malyugin ring is a versatile pupil expansion ring with high efficacy in femtosecond laser-assisted cataract surgery. Professor Boris Malyugin notes its advantages, having used it on a variety of classically difficult eyes and in complicated surgical cases.

Ongoing case series is revealing small-incision lenticule extraction to be better than surface ablation (SA) for all myopic laser corrections. However, SA still is useful in patients with thin corneas and therapeutic indications, according to Prof. Suphi Taneri.

Diabetes doubles the risk of cataract in the general population, with an even greater increased risk among people aged under 70, according to researchers.

The Malyugin ring is a safe alternative to traditional pupil-expansion approaches in cataract surgery. Here, best practice for safe surgery and a case study are described

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.

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.

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

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.

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.
