ICL sizing is a critical safety step and requires advanced diagnostics beyond standard refractive screening. These assessments contribute meaningfully to the overall cost.
Key diagnostic components
- Anterior chamber depth measurement
- White-to-white and sulcus-to-sulcus metrics
- Vault prediction modelling
- Endothelial cell count
- High-resolution anterior segment imaging
These tests ensure the lens fits safely and avoids complications such as excessive vault, angle narrowing or endothelial cell loss.
Why this affects cost
Sizing accuracy directly influences long-term safety. Clinics investing in advanced imaging (e.g., swept-source OCT, Scheimpflug tomography) incur higher diagnostic costs but reduce avoidable risk.
Typical UK ranges
Sizing and preoperative diagnostics typically account for £300-£600 of the total per-eye cost.
Clinical importance
Accurate sizing is non-negotiable. It is a governance-level safeguard, not an optional upgrade.
