Laser enhancement after previous LASIK can be suitable in some cases, but the thinner, altered cornea means careful safety checks are essential.
When an enhancement may be possible
Small residual prescriptions or regression can sometimes be refined with further laser.
- Stable refraction for at least several months
- Adequate residual stromal thickness confirmed by modern imaging
- Regular, healthy corneal shape with no signs of ectasia
- Clear link between current prescription and visual symptoms
- Realistic expectations about the magnitude of further improvement
When repeat laser is not advised
In some eyes, further tissue removal would place the cornea at risk.
- Thin or irregular corneas, or early signs of ectasia
- Large previous ablations leaving little tissue reserve
- Significant dry eye or surface disease since the first surgery
- Better alternatives such as lens surgery, corneal cross‑linking, or simply wearing light glasses
- Thorough risk-benefit discussion so any decision feels informed and comfortable
