PresbyMAX can exacerbate dry‑eye symptoms, so suitability depends on how well the condition can be controlled before surgery.
Concerns with dry eye
The ocular surface affects outcomes.
- Pre‑existing dryness can worsen after corneal laser
- Unstable tear film degrades vision and quality of multifocal optics
- Dryness increases risk of discomfort, fluctuating blur, and slower healing
- Severe dry eye is a relative or absolute contraindication
- Accurate measurements are harder when the surface is irregular
When it may still be possible
Optimisation can sometimes make surgery safe.
- Mild to moderate dry eye that responds to treatment and lid care
- Use of preservative‑free lubricants and anti‑inflammatory therapy pre‑operatively
- Objective improvement in tear‑film tests before proceeding
- Willingness to continue ongoing dry‑eye management after surgery
- Shared decision that benefits outweigh the risk of symptom flare
