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).
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.
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.

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.

High-intensity focused ultrasound cyclocoagulation is safe and effective in most refractory glaucomatous eyes. Complete success was achieved in 80% (24/30) of treated eyes that had undergone the maximum of three procedures.

The 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.
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.
Early 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.
Steroids are an important second-line treatment for the treatment of diabetic macular oedema. While side effects remain a concern, modern formulations of intravitreal steroid allow the treatment to be tailored to the individual patient.
In 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.
With its higher costs, FLACS failed to provide an additional benefit over phacoemulsification for patients or in healthcare settings, despite its advanced capabilities.

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.
An 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.
Although 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.
Ocular 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.
Cataract surgery assisted by viscosplit and crack with a new phaco tip gives good results compared with standard phacoemulsification, either bimanual or one-handed.
