5 documented risks. Severity reflects clinical significance, not probability.
Dry eye (transient or persistent)
minor50.00% (30.00–70.00%)Prevention: Pre-operative tear film assessment; lubricating drops; punctal plugs in selected patients.

Flap complications (dislocation, microstriae)
moderate0.50%Prevention: Femtosecond laser flap creation; protective shield first night; avoidance of eye rubbing.

Ectasia (corneal weakening)
severe0.05%Prevention: Pre-operative topography to exclude keratoconus; appropriate residual stromal bed thickness.

Under- or over-correction requiring enhancement
minor5.00% (2.00–10.00%)Prevention: Accurate pre-operative refraction; modern eye-tracking laser systems.
