Enhancement is designed to improve clarity, not merely acuity.
Modern wavefront-optimized and topography-guided ablation profiles ¹ ³:
- Minimise induction of higher-order aberrations
- Preserve contrast sensitivity
- Maintain night vision quality
Long-term studies show that properly planned enhancement does not reduce best-corrected visual acuity and may improve subjective visual quality when residual error is present ² ³.
Visual quality is not just about reading the 6/6 line.
It includes:
- Contrast
- Night driving performance
- Glare sensitivity
- Overall visual comfort
When performed with stable refraction, adequate corneal thickness, and proper centration, enhancement is a quality-restoring intervention ¹.
Done correctly, it refines optical performance without degrading it.
Enhancement is the final precision adjustment in a refractive pathway designed for long-term stability.
