Laser eye surgery is usually not suitable if your prescription is still changing, because ongoing change can undo the effect of treatment.
Why stability matters
Laser corrections are fixed to the current refraction, so further natural shifts will leave you back in glasses or needing further surgery.
- Recent changes of more than about 0.50 dioptres over a year suggest instability
- Young adults and teenagers are especially prone to ongoing myopic progression
- Underlying causes such as keratoconus must be excluded with corneal scans
- Waiting for stability reduces the chance of early regression or repeat procedures
- Glasses or contact lenses remain safest while prescriptions are evolving
When reassessment is sensible
Monitoring over time helps decide when surgery becomes a good option.
- Regular eye tests documenting refraction and corneal shape
- Addressing lifestyle or near-work factors that may drive progression
- Considering myopia-control strategies in younger patients
- Re-referral for surgical assessment once measurements plateau
- Using previous prescriptions to judge true long-term stability
