Wavefront-guided LASIK is a customised laser eye surgery that uses measurements of the entire optical system, not just basic prescription, to refine the ablation pattern. It aims to reduce higher-order aberrations and improve visual quality.
Wavefront Measurement
A wavefront aberrometer sends light into the eye and measures how it returns, generating a detailed map of optical imperfections. This data guides the excimer laser to address subtle distortions as well as myopia, hyperopia, and astigmatism.
- Particularly helpful for patients with larger pupils or night-vision issues
- Requires stable, high-quality measurements before surgery
- Can be combined with femtosecond flap creation
- Some patients may not be suitable if aberration patterns are irregular or unstable
Benefits and Considerations
Many patients achieve excellent sharpness and contrast with reduced glare or halos, though standard LASIK already provides very good outcomes for most. Results depend on accurate data and corneal thickness.
- Screening rules out corneal disease and ensures adequate tissue
- Post-operative care mirrors that of conventional LASIK
- Enhancement procedures may again use wavefront data if necessary
- Technology is one factor; surgeon experience remains critical
