How to improve IOL power calculations in keratoconusOne 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).

Adopting a multidiagnostic method for characterising the anterior segmentA 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.

Long-term observation of SMILE gives better myopia prognosisLong-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.

MICS & MIGS: combined surgery with microstent devicesThe combination of MICS and MIGS can offer an effective surgical treatment for POAG when the reduction of IOP following cataract surgery alone is not sufficient to reduce a patient’s need for glaucoma therapies.

Reducing posterior capsular ruptureRounded 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.

Advancing diagnostics and detection of neovascular age-related macular degenerationEarly detection and treatment is essential to preserve vision in patients with age-related macular degeneration. A new device, the ForeseeHome®, uses preferential hyperacuity perimetry for early detection of choroidal neovascularisation before symptoms develop.

Real-world strategies for wet AMDIn many clinical areas, early consultant-led intervention has been shown to improve clinical and patient-reported outcomes and to reduce overall treatment costs. This paper reconfirms this finding in the treatment of wet age-related macular degeneration (wet AMD) and presents data from a publicly funded NHS fast-track (FT) centre in north-west England that aims to see and treat patients within 48 hours of referral.

Are extended-depth-of-focus IOLs hitting the visual sweet spot?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.

Experience with a single-use, preassembled silicone I/A tip systemAn I/A tip system comprises a preassembled, single-use silicone I/A tip, which has advantages over other commercially available products. It helps to reduce capsular rupture during cataract surgery and also eliminates tricky tip assembly and cleaning.

Why you need to beware of potential mimickers of paediatric glaucomaAlthough the diagnosis of primary congenital or early developmental glaucoma is often straightforward, similar phenotypic features can occur in other paediatric conditions, which are consequently sometimes mistaken for early childhood glaucoma. Ophthalmologists who care for children with glaucoma must keep such potential mimics in mind.

How to manage cataracts with ocular surface diseaseOcular surface disease, including dry eye disease, is common in patients undergoing cataract surgery. It must be treated in order to optimise the ocular surface prior to surgery, and close follow-up in the postoperative period is important.
