Lens replacement surgery is usually not the first choice for people under 40, because their natural lens still has useful focusing power.
Why it is less common under 40
In younger adults, the lens can still change shape to focus at different distances. Removing it removes this natural ability permanently, so other treatments are often safer and more appropriate.
- Under 40, laser eye surgery or implantable contact lenses are usually considered first
- Keeping the natural lens preserves future focusing flexibility
- Early lens removal may slightly increase some long-term risks, such as retinal problems
- The benefits may not outweigh these risks when vision is otherwise healthy
- Careful expert assessment is essential before considering surgery at this age
When it might be considered
There are rare situations where lens replacement may be discussed in younger people. Decisions are made case by case, with detailed explanations of long-term effects.
- Very high prescriptions where other treatments are not suitable
- Early cataract or lens changes affecting daily activities
- Strong desire for independence from glasses after full counselling
- Healthy retina and cornea with stable prescription
- Willingness to commit to lifelong eye monitoring
