PRESBYOND is specifically designed to provide functional correction at both distance and near using blended‑vision laser profiles.
How it targets both ranges
Each eye contributes differently.
- Dominant eye is biased toward distance, non‑dominant toward near
- Aspheric profiles extend depth of focus in each eye
- Binocular summation provides a broad continuous range of clear vision
- Many patients function well without glasses for most tasks
- Occasional spectacles may still be used for very demanding activities
Key suitability factors
Not everyone adapts equally.
- Good binocular vision and tolerance of slight inter‑ocular difference
- Stable prescription, healthy corneas, and clear lenses
- Realistic expectations about possible halos or contrast changes
- Successful trial of blended or monovision contact lenses, where used
- Thorough counselling to ensure goals match what PRESBYOND can deliver
