Laser surgery permanently alters corneal curvature to match your current prescription.
If that prescription is still changing, the correction may become inaccurate over time.
Professional guidance generally requires stable refraction, typically defined as ≤0.50 dioptres change within 12 months, before proceeding. ¹
Myopic progression is most common in adolescence and early adulthood. ² Younger patients also have higher incidence of early keratoconus, making careful topographic screening essential. ³
Red flags include:
- Increasing myopia over the past year
- Recent axial length growth
- Age under 21 with borderline tomography
- Family history of progressive ectatic disease
Performing corneal laser during active refractive change risks regression or need for enhancement procedures.
At Blue Fin Vision®, stability is documented before intervention. “Not yet” is often the correct answer for young patients.
Timing is part of safety.
Waiting for biological stability may reduce lifetime procedures and improve predictability.
Laser surgery is elective. It should be performed at the right moment, not simply the earliest possible one.
