Current IOL designs offer a variety of optical options for the correction of presbyopia. Regardless of the principal of correction, compromise is required. However, a new class of IOLs, currently referred to as extended-depth-of-focus IOLs (EDOF-IOLs), seems to be generating very satisfied patients.

Incorrect IOL power is one of the most frequent reasons for IOL exchange following cataract surgery. Different options for the correction of residual refractive errors are being developed, including piggyback IOLs, light-adjustable lenses and multicomponent IOLs.

The Novel Evidenced Assessment of Tortuosity (NEAT) system is intuitive and works even with poor images, according to its creators, Konstantinos Balaskas and his colleagues at Manchester Royal Eye Hospital and five other centres in the United Kingdom.

Though there is scant research to guide treatment, tea tree oil shampoo might successfully improve some cases of blepharitis, according to two physicians at the Eye Unit, Southampton General Hospital, Southampton, United Kingdom.

Rounded phaco tips reduce the risk of posterior capsule rupture, increasing the safety of phacoemulsification. The Dewey Radius Tip, which is used exactly like a sharp-edged phaco needle, has rounded edges. This reduces the risk of posterior capsule rupture during cataract surgery.

The submerged cornea using backgrounds away (SCUBA) peeling technique may be more effective than the newer Muraine technique for preparing endothelial donor grafts for Descemet membrane endothelial keratoplasty (DMEK).

Ocriplasmin (Jetrea, ThromboGenics) is an option for the management of patients who have full-thickness macular hole (FTMH) and vitreomacular adhesion, according to an article in press in the American Journal of Ophthalmology.

Corneal collagen crosslinking (CXL) with epithelial disruption appears to safely and effectively treat keratoconus or iatrogenic corneal ectasia, according to a study recently published in Eye. In fact, patients may tolerate the approach better than they tolerate the technique involving complete removal of the epithelium, say the authors, from the Corneoplastic Unit and Eye Bank of Queen Victoria Hospital in East Grinstead, UK.

In SMILE the anterior-most stromal lamellae remain intact postoperatively. Here, the author discusses the biomechanical advantages of preserving the stronger anterior stroma and the resulting effects on spherical aberration control and optical quality.

Intracameral antibiotic therapy helps prevent endophthalmitis after cataract surgery, while topical antibiotic therapy does not, according to a literature review conducted by researchers from Denmark and published online in Acta Ophthalmologica.

A new trifocal diffractive IOL (FineVision trifocal IOL, PhysIOL), implanted bilaterally, achieved a full range of adequate vision, satisfactory contrast sensitivity, and a lack of significant adverse photic phenomena, according to Spanish researchers reporting in BMC Ophthalmology.

Intravitreal ranibizumab (IVR) has been found to improve vision related quality of life in diabetic macular oedema (DME) patients, notes a study recently published in the Journal of Diabetes and Its Complications.
