Observational analysis shows associations between pupil size and visual outcomes in lens surgeries, suggesting implications for lens design.
Preoperative and postoperative pupil size ≥4.0 mm, as measured by Anterion, was associated with better UCDVA with enhanced monofocal intraocular lenses. However, further research is needed to confirm if this results from the lens design or physiological confounders like diffraction. Measurement discrepancies between AS SS-OCT devices highlight the need for standardisation.
