Most ocular structures become luminescent for a short time when exposed to a light source of appropriate wavelength; this phenomenon is known as autofluorescence (AF). AF is due to the presence of fluorescent substances called fluorophores.

Rose is a rose is a rose is a rose--a line written (1913) by Gertrude Stein and its variations in a famous quotation are often interpreted as meaning “things are what they are--makes a statement of the law of identity, and in the post-factum age is ever more meaningful. An ophthalmologist could as well write: “Cataract is a cataract is a cataract is a cataract,” ICD-10 Code H25.0 for the diagnosis “Cataracta senilis incipiens” in its earliest stage and notably with a surgical history of more than 2,500 years.
Companies are exploring light-sensitive proteins method in patients with advanced disease.
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.
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).

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.
