Published: April 9, 2024

The global all-ages prevalence of epidemiologically-measured 'functional' presbyopia was estimated at 24.9% in 2015, affecting 1.8 billion people. This projected to stabilise 24.1% 2030 due increasing myopia, but affect more people (2.1 billion) population dynamics. Factors the include age, geographic location, urban versus rural sex, and, a lesser extent, socioeconomic status, literacy and education, health inequality. Risk factors for early onset included environmental factors, nutrition, near demands, refractive error, accommodative dysfunction, medications, certain conditions sleep. Presbyopia found impact on quality-of-life, particular quality vision, labour force participation, work productivity financial burden, mental health, social wellbeing physical health. Current understanding makes it clear that is very common age-related condition has significant impacts both patient-reported outcome measures economics. However, there are complexities defining epidemiological studies. Standardisation definitions will assist future synthesis, pattern analysis sense-making between

Postoperative assessment of monocular multifocal bi-aspheric ablation pattern for correcting myopia with presbyopia

Published: April 14, 2025

Purpose : This study aimed to evaluate the vision performance of monocular multifocal bi-aspheric ablation pattern (PresbyMAX® mode) for correcting myopia and presbyopia. Methods: Consecutive case series, a total 22 consecutive patients (10 males 12 females) who underwent in non-dominant eye(Near Eye, NE) mono-focal regular FS-LASIK dominant eye(Distance DE) correction presbyopia were reviewed 6 months. Visual acuity assessments, encompassing uncorrected distance (UDVA), intermediate (UIVA), near (UNVA), corrected visual (DCNVA), conducted preoperatively at 1 day, week, month, 3 months, months postoperatively. Additionally, patients' primary complaints, contrast sensitivity (CS), defocus curves, subjective questionnaires also assessed. Results: Binocular UDVA (BUDVA) averaged -0.02±0.06 logMAR, binocular UIVA (BUIVA) UNVA(BUNVA) -0.07±0.05 logRAD -0.05±0.06 logRAD, respectively. All achieved BUDVA 0.1 logMAR or better, BUIVA 0 BUNVA along with improved ratings.CS exhibited no significant changes. Defocus curves indicated satisfactory acuity, surpassing 0.3logMAR both eyes within range +1.5D -3.0D. Common reported issues included blurred vision, glare, dry eye symptoms. Overall, patient satisfaction was 100%, 95% individuals achieving independence from spectacles. Conclusions: The PresbyMAX mode is safe effective myopic presbyopia, leading high levels satisfaction.

SIGNIFICANCE Evaluating the visual challenges and refractive correction solutions of presbyopic orienteers identifies features relevance to optometric management needs active presbyopes. PURPOSE Orienteering is a unique sport requiring clarity at range viewing distances has high proportion participants. This study evaluates vision corrections used by orienteers, specifically aiming characterize prevalence different options explore strengths limitations solutions. METHODS Orienteers 40 years or older completed an online questionnaire consisting multiple-choice questions covering personal demographics, orienteering participation, worn in everyday life for orienteering. Free-text asked further information about advice received from eye care practitioners were analyzed using content analysis. RESULTS There 469 respondents (195 women, 274 men; median age category, 55 59 years).

Objective To determine the agreement between measurements of accommodative amplitude (AoA) in children using a specialised rule and measurments without it. Methods A total 502 underwent optometric examinations, including measurement visual acuity, objective subjective refraction. AoA were done with Berens rule. The conducted monocularly −4 D lens. fixation stick containing English letters equivalent to 20/30 acuity long millimetre ruler was used measure This performed by two trained examiners. these methods reported 95% limits (LoA) interclass correlation coefficient (ICC).
