Presbyopic laser enhancement after PRK or LASEK is sometimes possible, but only if corneal thickness, shape, and stability remain suitable.
Potential indications
It can address new presbyopic needs.
- Previous surface laser for myopia or hyperopia with good long‑term stability
- Adequate residual corneal thickness and regular topography
- Presbyopia now leading to increased reliance on reading glasses
- Preference for corneal rather than lens‑based correction at this stage
- Clear lenses and healthy posterior segment
Risks and limitations
Re‑treating the cornea demands caution.
- Risk of haze, regression, or dry eye may be higher with repeat ablations
- Limited tissue budget may restrict achievable correction
- Any irregularity or ectasia signs make further laser inappropriate
- Alternatives such as lens replacement might offer a more robust long‑term solution
- Case‑by‑case evaluation in an experienced refractive clinic is essential
