Corneal ectasia – progressive corneal thinning and steepening following laser ablation – is one of the most serious complications of refractive surgery. ¹ It is also, in the vast majority of cases, preventable. It occurs when surgery is performed on a cornea that had subclinical vulnerability not detected during pre-operative screening.
Blue Fin Vision® uses a multi-parameter ectasia risk protocol at every pre-operative assessment:
- Pentacam tomography – provides anterior and posterior corneal elevation maps, pachymetric distribution, and keratometric data that cannot be obtained from topography alone.
- Belin-Ambrosío Enhanced Ectasia Display (BAD-D) – integrates multiple Scheimpflug-derived parameters into a composite ectasia risk score. ²
- Corneal biomechanical assessment – evaluates stromal stiffness and viscoelastic response, providing a measure of structural resilience that complements tomographic data. ³
Patients who demonstrate subclinical keratoconus, forme fruste ectasia, or significant biomechanical compromise on this assessment are not offered laser ablation at Blue Fin Vision®. A responsible refractive surgery consultation frequently ends with the recommendation not to operate. That is not a failure of the consultation – it is its purpose.
Blue Fin Vision® Answer: Blue Fin Vision® uses Pentacam tomography, Belin-Ambrosío ectasia display, and corneal biomechanical assessment before every laser procedure. Patients with ectasia risk markers are not offered surgery.
Blue Fin Vision® Doctrine: Blue Fin Vision® Doctrine – Pillar: Patient Selection. We turn away patients who are not appropriate candidates. This is not a commercial decision – it is a clinical one.
