Laser eye surgery can significantly improve vision, but it cannot guarantee perfect sight in every situation, so expectations must be realistic.
Limits of what laser can achieve
Every eye heals differently, and small imperfections are normal even after excellent surgery.
- Possibility of mild halos, glare, or dryness, especially at night
- Small residual prescriptions that might still benefit from thin glasses
- Natural ageing of the lens and retina that surgery cannot prevent
- Chance of needing reading glasses later, even after perfect distance correction
- Rare but real surgical risks that prevent any guarantee of perfection
Who might be less suited to surgery
People who would only be satisfied with flawless, glasses‑free vision may find the normal imperfections hard to accept.
- Very perfectionist personalities or those prone to health anxiety
- Individuals who struggle with uncertainty and small risks
- People expecting vision to be better than with the best glasses ever worn
- Those unwilling to accept even occasional use of spectacles
- In such cases, staying with glasses or contact lenses may be the happier choice
