Purpose: To identify the predictors of visual outcomes (visual acuity and visual function) in cataract surgery patients in Singapore and compare the visual outcomes of phacoemulsification and extracapsular cataract extraction (ECCE).
Setting: Singapore National Eye Center, Singapore, Republic of Singapore.
Methods: The visual function was measured by the VF-14 and visual acuity in the operated and the better eye in 460 systematically sampled cataract surgery patients preoperatively and 3 months after surgery. Several patient- and surgery-related predictive factors were recorded.
Results: After cataract surgery, 85.1% of patients reported improved visual acuity in the operated eye and 77.6% reported improved visual function. Patients with poorer visual acuity and visual function at baseline reported greater improvements in visual acuity and visual function. Patients who had phacoemulsification had better final visual function (P =.006) and better final visual acuity (P <.001) scores. In multiple linear regression models, final visual function was better in patients without preexisting eye disease and with better baseline visual function, and final visual acuity in the operated eye was better in patients who were younger, were better educated, had no preexisting conditions or postoperative complications, and had a better baseline visual acuity.
Conclusions: Patients with poorer baseline visual acuity or who had no preexisting eye disease reported more improvement in visual acuity in the operated eye. Several factors including no preexisting eye disease were associated with better final visual acuity and visual function scores.

Spaceflight-Associated Neuro-Ocular Syndrome (SANS) presents a critical risk in long-duration missions, with microgravity-induced changes that threaten astronaut vision and mission outcomes. Current SANS monitoring, limited to pre- and post-flight exams, lacks in-flight diagnostics, highlighting an urgent need for autonomous tools capable of real-time assessment. Grok, an AI platform by xAI, offers promising potential as an advanced diagnostic tool for space-based health monitoring.

With increasing advancements and efforts towards space exploration, there is a pressing need to understand the impacts of spaceflight on astronauts' health. Astronauts have reported signs and symptoms of dry eye disease upon traveling to the International Space Station (ISS), thus necessitating an evaluation of the factors that contribute to the onset of spaceflight associated dry eye disease. Prior literature describes the hypercapnic environment of the ISS; however, the link between the high CO levels and astronauts' symptoms of dry eye disease remains unexplored.

Department of Binocular Vision Pathophysiology and Strabismus, Medical University of Lodz, University Barlicki Hospital No.1, Lodz, Poland.
Purpose: To determine the effect of low hypermetropia correction and orthoptic exercises on binocular visual function in children with symptomatic convergence insufficiency.
Methods: This was a prospective, randomized intervention with a 3-month follow-up. Consecutive pediatric patients with convergence insufficiency and hypermetropia who met inclusion criteria were randomly assigned to one of three treatment groups: spectacle correction and orthoptic training (group 1), spectacle correction alone (group 2) and orthoptic training alone (group 3).

Robert O Curle Ophthalmology Suite, Institute for Regeneration and Repair, The University of Edinburgh, Edinburgh, UK.
Purpose: To determine whether imaging features derived from fundus photographs contain 3D eye shape information beyond that available from spherical equivalent refraction (SER).
Methods: We analysed 99 eyes of 68 normal adults in the UK Biobank. An ellipsoid was fitted to the entire volume of each posterior eye (vitreous chamber without the lens)-segmented from magnetic resonance imaging of the brain.
'Such a lot of bother': Qualitative results of a home trial of a wearable electronic vision enhancement system for people with age-related macular degeneration.

Vision and Hearing Sciences Research Centre, Anglia Ruskin University, Cambridge, UK.
Purpose: Wearable electronic low vision enhancement systems (wEVES) improve visual function but are not widely adopted by people with vision impairment. Here, qualitative research methods were used to investigate the usefulness of wEVES for people with age-related macular degeneration (AMD) after an extended home trial.
Methods: Following a 12-week non-masked randomised crossover trial, semi-structured interviews were completed with 34 participants with AMD, 64.
