Short answer
Presbyopia is lens stiffening — reading blur from your mid-40s. Cataracts are lens clouding — misty vision, faded colours, and glare, often from the 60s. Both affect the same lens; phacoemulsification + IOL treats both — RLE proactively before clouding, cataract surgery when the lens is cloudy.
Cataracts vs presbyopia at a glance
| Feature | Cataract | Presbyopia |
|---|---|---|
| What changes | Lens becomes cloudy — scatters light | Lens stiffens — cannot focus up close |
| Typical age | Often 60+ (earlier with diabetes, steroids) | Mid-40s onward — everyone |
| Distance vision | Usually blurs as cataract progresses | Often unchanged if no other error |
| Colours / glare | Faded colours, night glare | Less colour change; near blur main sign |
| Glasses help? | Partially at first — not once advanced | Reading glasses help until surgery |
| Surgery | Cataract surgery | RLE with premium IOL |
| Same operation? | Yes — phaco + IOL. Timing and lens clarity differ. | |
Can you have both?
Very common over 55. A trifocal IOL at cataract surgery can correct clouding and reading vision together — addressing presbyopia symptoms in the same procedure.
