YAG capsulotomy can sharpen vision when PCO is present, but it cannot guarantee perfect sight, so very perfectionist expectations need careful discussion.
What YAG can and cannot do
It specifically clears capsule haze.
- Can improve clarity, contrast, and reduce glare caused by PCO
- Cannot correct other problems such as macular disease or irregular astigmatism
- Does not change the power or design of the intraocular lens
- Carries small risks, including floaters, pressure rise, and rarely detachment
- May still leave minor imperfections that require glasses
Who may be less suited
Certain expectations make satisfaction unlikely.
- People who will only accept flawless, glasses‑free vision in all conditions
- Those highly anxious about any small visual side‑effects
- Patients who already have multiple other eye conditions limiting potential
- Individuals focusing on tiny visual differences that may persist post‑YAG
- In such cases, shared decision‑making may conclude that monitoring is wiser
