Lens replacement surgery can be suitable if you have large pupils, but special care is needed when choosing lens type because night-time visual effects may be more noticeable.
How large pupils affect surgery
When pupils are large in dim light, more of the lens edge is exposed. Certain lens designs, especially multifocal ones, can produce halos or glare that feel stronger in these situations.
- Measurements of pupil size are taken in different lighting conditions
- Large pupils may influence whether multifocal lenses are advised
- Monofocal or extended-range lenses may give smoother night vision
- Driving at night is discussed carefully during planning
- Glare-reducing coatings on glasses can help if needed
Making the right choice
A personalised approach balances visual freedom with comfort. Understanding your activities and sensitivity to visual phenomena guides lens selection.
- Tell your surgeon if you already notice halos from streetlights or headlights
- Consider how often you drive in the dark or work in low light
- Trial contact lenses mimicking monovision may help decision-making
- Realistic expectations about small halos often improve satisfaction
- Follow-up visits check adaptation and address any persistent symptoms
