Cataract & Refractive

In this article, Dr Kov?cs discusses his recent study evaluating whether femtosecond laser-assisted capsulotomy has an effect on the incidence of PCO when compared to the manual technique.

In this article, the authors discuss their research into alkylphosphocholine coated IOLs, which may offer some hope in the prevention of PCO in the future.

A diffractive trifocal IOL (FineVision, PhysIOL) provides a peak modulation transfer function for intermediate vision.

Posterior capsule opacification (PCO) is a frequent and important complication noticed in diabetics undergoing cataract surgery, however, few studies have examined the prevalence of PCO in diabetic versus non-diabetic patients. Therefore, the authors performed a study exploring the long-term effect of diabetes on the incidence of PCO and here they highlight their findings.

Bromfenac ophthalmic solution 0.07% (Pro-Lensa, Bausch + Lomb) used once a day results in zero-to-trace (0–5 cells) cell severity in the anterior chamber following cataract surgery with implantation of a posterior chamber IOL, according to newly published research.

Dropper bottles are the delivery vehicle of choice of patients using autologous serum eye drops daily for severe ocular surface disorders, according to a newly published study.

Environmental factors have been discussed as possible triggers for diseases. Recently, the authors analysed the impact of seasonality and distinct meteorological parameters on refractive and visual outcome of LASIK in myopic eyes, here, they present the highlight of this study.

Results of a study comparing matched groups of eyes undergoing myopic correction by small-incision lenticule extraction (SMILE) or LASIK show that the optical quality was better and the cornea retained higher tensile strength after the flapless SMILE procedure.

In this article, the authors discuss their study that was aimed at evaluating the rotational stability and patient visual quality of a toric IOL with a novel haptic design.

In this article, Dr Schallhorn reveals the results of a large case series that provides evidence that there is no need to reject candidates for LASIK on the basis of pupil size or to increase the treatment zone size for such patients.

Implantation of a capsular tension ring effectively reduces the percentage area of posterior capsular opacification (PCO) and the Nd:YAG laser capsulotomy rate in patients with highly myopic eyes, according to researchers in Albania and Turkey.

In children, implantation of a multifocal IOL remains a topic of debate. With lacking evidence on post surgery outcomes and no head-to-head comparison of multifocal IOLs in children, this issue remains to be clarified. Therefore, the authors of this article were prompted to perform research in this area to address a number of concerns among paediatric ophthalmologists.

In this article, Dr Portaliou discusses a new multi-component adjustable lens that may be the answer paediatric ophthalmologists have been waiting for.

Determining the optimal IOL power for children is as much an art as a science.

Several new refractive surgical platforms have been introduced recently and many ophthalmologists are discovering they find the new technologies to be more efficient and produce better results.

Cataract patients who have astigmatism of greater than 2.5 D are likely to benefit more from the implantation of a high-cylinder toric intraocular lens (IOL) than from the implantation of a low-cylinder toric IOL combined with limbal relaxing incision (LRI), according to research conducted at the Ouchi Eye Clinic and Kyoto Prefectural University of Medicine, Kyoto, Japan

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.

Dr Trattler focuses on the incidence of topographic abnormalities in patients before surgery, emphasizing the importance of pre-op topography to better understand the patient's corneal shape and enable better prediction of post-op outcomes.

According to Prof. Shah, the second generation Lentis multifocal lens is a significant improvement over its predecessor. In this article, we highlight his study assessing visual outcomes after implantation with this new lens.

Consideration of all the available options should be made to correct refractive surprises, emphasized Dr Noel Alpins (NewVision Clinics, Cheltenham, Victoria, Australia) when speaking during the 'Assessment of Astigmatism' session at the 2013 ESCRS Congress.

Various models of mutlifocal IOLs are currently available that enable patients to see at two focal points (distant and near). These lenses have demonstrated good safety, efficacy and predictability in correcting ametropia and presbyopia after phaco surgery although some visual side effects have been observed.

Dr Morris recently discussed his study, evaluating the Lentis MF-15 toric lens as an effective treatment for astigmatism despite having a low add power. Here, we present the key outcomes of his talk.

The authors discuss their study evaluating and comparing the post-op PCO levels, anterior capsule retraction and ACO of two single-piece hydrophobic acrylic lenses.

Corneal astigmatism may be reduced or nearly eliminated after intrastromal femtosecond laser astigmatic keratotomy, explains one ophthalmologist.

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.
