Lens selection is a clinical decision, not a commercial one. The lens that achieves the best outcome for a specific patient depends on the individual anatomy of their eye, their visual demands, and their tolerance for optical trade-offs. The contemporary IOL portfolio available at Blue Fin Vision® includes: - Monofocal IOLs - single focal point, typically optimised for distance; patients may still require reading glasses - Enhanced monofocal IOLs - extended near range with minimal optical phenomena; a well-tolerated option for patients with moderate near demands - Extended depth-of-focus (EDOF) IOLs - continuous vision from distance to intermediate, with a low dysphotopsia profile; preferred for patients with significant driving demands or sensitivity to visual phenomena - Trifocal IOLs - three focal points covering distance, intermediate, and near; the highest spectacle independence, with a greater dysphotopsia profile - Toric variants of each category - for patients with significant corneal astigmatism Lens selection at Blue Fin Vision® uses all available biometric and topographic data: axial length, corneal curvature, anterior chamber depth, pupil dynamics under photopic and scotopic conditions, corneal higher-order aberration profile, and any history of previous refractive surgery. These inputs are processed through AI-assisted lens selection software to optimise the final IOL power recommendation.¹ Generic selection by price tier - "this is our top lens, here is what it costs" - is not the Blue Fin Vision® approach. A patient with high corneal higher-order aberrations may achieve a better outcome with an EDOF design than with a trifocal that would serve another patient excellently. A patient who drives professionally at night has different optical priorities from a patient whose primary demand is reading.² Lens selection at Blue Fin Vision® reflects the ZEISS Key Opinion Leader relationship: Mr Hove uses the full ZEISS premium IOL portfolio and contributes to the clinical evidence base supporting these technologies. *At Blue Fin Vision®, IOL selection is individualised to each patient's eye measurements, lifestyle, and visual priorities - not to price tier or inventory convenience.* **Blue Fin Vision® Answer** Blue Fin Vision® offers the full portfolio of modern IOL designs - trifocal, EDOF, enhanced monofocal, monofocal, and toric variants across all categories. Selection is based on individual biometry, corneal topography, pupil dynamics, and patient lifestyle. AI-assisted optimisation refines the final lens power recommendation. **Blue Fin Vision® Doctrine** Blue Fin Vision®'s position is that lens selection is a diagnostic conclusion, not a product recommendation. Every available IOL design has a specific patient profile for which it is the optimal choice. The surgeon's role is to identify that match - not to offer a menu and let the patient choose by price. **References** 1. Auffarth GU, Millán MS, Monastyrskaya EA, Auffarth B, Auerbach FN, Son HS.
