New device for anterior segment analysis. CSO recently introduced its MS-39 anterior segment OCT and Osiris ocular aberrometer. The MS-39 device provides ultra-high-resolution tomographic sections of the anterior segment, as well enabling the measurement of key parameters for evaluating candidates for premium cataract surgery. When combined with the Osiris ocular aberrometer, clinicians are able to access high precision pre- and post-operative wavefront analysis of 45,000 points, enabling them to quantify toric IOL rotation based on aberrometry, study any internal ocular aberrations, and estimate post-rotation refraction so as to achieve optimal visual outcomes for their patients.

Myopia 2025: Innovations. Organized in cooperation with the Department of Ophthalmology, the Foundation for the Development of Ophthalmology “Ophthalmology 21,” and the University of Warmia and Mazury, Poland, this myopia-focused conference will take place online on June 20th, 2025. Focusing specifically on Europe, topics will include: myopia epidemiology, low-dose atropine use for myopia management, and a panel discussion titled “Who should control myopia, and how? A European perspective.” Link
Keratoconus prevalence in ageing populations. Assessing the prevalence of keratoconus among individuals aged 60 years and older, a population-based Cornea study has determined that over 5 percent of 60+ adults have the disease. The Iran-based team also found that KCN prevalence “tends to rise with advancing age”, highlighting the need for corneal tomography and topography in helping to guide clinical decisions for this patient demographic.

ChatGPT sits exams. A Vision study has evaluated how well ChatGPT models performed on real European Board of Ophthalmology Diploma exam questions. While ChatGPT-4o performed at – or above – the human pass mark on multiple-choice questions, both versions significantly underperformed on single best answer (SBA) questions, indicating limitations in clinical reasoning and higher-order integration. The findings suggest that while ChatGPT shows promise as a tool for ophthalmic education and exam benchmarking, it is not yet a substitute for human clinical expertise. Link
EVs’ contribution to corneal transplants. A new Japanese study has demonstrated that extracellular vesicles (EVs) derived from corneal grafts play a significant role in triggering immune responses during the acute phase of corneal transplantation. The Nihon University School of Medicine researchers found that graft-derived EVs carrying donor antigens rapidly migrate to cervical lymph nodes and are taken up by host immune cells, contributing to graft rejection through a semi-direct antigen presentation pathway. The study presents the first evidence that EVs alone – without accompanying donor cells – can provoke allorecognition and influence graft survival in corneal transplants. Link
