IOL power in short eyes
Prospective analysis of 269 eyes of 269 patients between 2017 and 2020, with axial length (AL) of 22mm or less. New principles for calculating IOL power were recently developed, including formulas based on paraxial ray-tracing (Barrett and Olsen) and based...
Comparing tensile strengths of two scleral fixated intraocular lenses: CT-Lucia and MA60
The authors designed a benchtop model to measure the tensile strengths and resistance to breakage of the haptics and haptic-optic junctions of the CT Lucia 602 (Carl Zeiss, California) and AcrySof MA60 (Alcon Laboratories, Texas) IOLs. For the haptic breakage...
Causes of abnormal head postures – literature review
Yadegari reports a narrative literature review for abnormal head postures (AHPs) with discussion on different causes. This review summarises the control of a normal head posture before discussing differences of ocular vs non-ocular AHPs. Ocular AHPs may be adopted to...
Changes in phoria measurements after physical activity
This study aimed to evaluate effects of physical activity (aerobic and anaerobic) on the latent eye deviation. The study recruited 20 competitive soccer players (10 myopes (mean -0.63D) and 10 emmetropic: 19 males), who underwent a total 90-minute exercise of...The Association of British Dispensing Opticians (ABDO) achieves carbon neutrality

Intravitreal afibercept and ranibizumab for PCV
This is a retrospective, interventional series comprising 98 eyes with polypidal choroidal vasculopathy (PCV) with the aim of comparing treatments with afibercept and ranibizumab, highlighting any differences in their efficacy. Case notes and imaging (FFA / ICG / OCT) were...
Amblyopia information provided by chatbots – how readable and understandable is this?
The purpose of this study was to evaluate the understandability, actionability and readability of responses to frequently asked questions about amblyopia provided by ChatGPT-3.5, Bing Chat, Bard and the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) website, along with...The challenge of chorioretinal folds in virtual eye clinics
Chorioretinal or choroidal folds are parallel striations involving the retina, retinal pigment epithelium (RPE), Bruch’s membrane, and inner choroid [1]. They can arise from compressive stress on these layers, and their presence often serves as a diagnostic marker for underlying...
