Emerging Microbial Trends That Could Affect Your Practices

A triptych of challenges paints a concerning picture for ophthalmologists across the globe.

The end isn’t nigh, but challenges do lurk beyond the horizon. In a recent presentation, Kyung Sun Na MD, PhD outlined the three primary emerging trends in the microbial sphere that ophthalmology needs to contend with...

AI Analysis and the Cornea

A combination of better imaging and AI deep learning could significantly improve corneal imaging and diagnosis.

AI-driven widefield specular microscopy promises an unprecedented improvement in imaging for Fuchs’ corneal endothelial dystrophy (FCED), recent studies from Singapore suggest...

Need to Know: Spherical Aberration

Part three of this series examines spherical aberration and its influence on higher-order aberrations.

Spherical aberration (SA) is a rotationally symmetrical aberration belonging to the fourth order, together with secondary astigmatism and quadrafoil. SA occurs secondary to the lens refracting...

The True Cost of Shingles Shots

Increasing access to vaccines that prevent ophthalmic shingles could save taxpayers money.

What is the true value of a vaccine: the initial cost or the expense of long-term treatment of the unvaccinated?

Need to Know: Aberrations, Aberrometry, and Aberropia

Understanding the nomenclature and techniques.

Optical quality of the eye is affected not just by higher-order aberrations (HOAs) but also by diffraction and scatter. Thus, even the perfect lens has a limit to its resolution...

José Güell: Trends in Cornea Treatment

Endothelial damage, cellular treatments, human tissue, and infections are key concerns on the horizon.

José Güell, head of the Cornea, Cataract, and Refractive Surgery Department at IMO Grupo Miranza in Spain, shares the key issues he sees in the field of cornea treatment.

Need to Know: Higher-Order Aberrations and Polynomials

This first instalment in a tutorial series will discuss more on the measurement and clinical implications of HOAs.

Aberrations of the eye can be chromatic or monochromatic. Chromatic aberrations are caused by light dispersing into its component wavelengths, with different wavelengths focused at slightly different points...

Emerging Technology for Detecting Subclinical Keratoconus

Brillouin microscopy shows promise in clinical studies.

In screening laser refractive surgery candidates, distinguishing normal corneas from those with subclinical keratoconus is challenging. Ongoing studies suggest motion-tracking Brillouin microscopy may eventually provide a more reliable method for doing so...

Knowing Iris Repair: Modified Trifold Technique

Part eight of our series covers the modified trifold technique for large iris defects.

This article discusses the trifold technique, which is a combination of trocar-assisted iris repair and single-pass, four-throw pupilloplasty (SFT). Dr Agarwal and I described the trifold technique for repairing non-apposable large iris defects, and I modified it further to circularize and centralize the pupil.
