# Does Enhancement Affect Long-Term Vision Quality?

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.
