Article: Types of Lenses for Cataract Surgery – A Complete Guide to IOLs
Cataract surgery doesn’t just remove a cloudy lens—it replaces it with a new one. These artificial lenses, called intraocular lenses (IOLs), come in various types, each designed to suit different visual needs. Understanding the types of lenses for cataract surgery will help you make an informed choice for better vision.
1. Monofocal Lens
Focus: One distance (usually distance)
Best For: People who don’t mind using glasses for near or intermediate vision
Pros: Clear vision at a fixed distance, cost-effective, most commonly used
Cons: Requires reading glasses
2. Multifocal Lens
Focus: Multiple distances (near, intermediate, and far)
Best For: Patients who want to reduce dependence on glasses
Pros: Vision correction across ranges
Cons: May cause glare or halos at night
3. Toric Lens
Focus: Corrects astigmatism + distance vision
Best For: People with corneal astigmatism
Pros: Sharp vision for those with astigmatism
Cons: Doesn’t correct near or intermediate vision
4. EDOF (Extended Depth of Focus) Lens
Focus: Continuous range of vision from distance to intermediate
Best For: Active individuals and computer users
Pros: Less glare than multifocal, smooth vision range
Cons: Reading glasses may still be needed
5. Accommodative Lens
Focus: Shifts focus with eye movement
Best For: People wanting a natural lens feel
Pros: Mimics natural eye movement for better range
Cons: Results may vary depending on eye condition

Conclusion:
Choosing the right type of lens for cataract surgery depends on your vision goals, budget, and eye health. Whether you prefer clarity at one distance or want to ditch glasses altogether, there’s an IOL designed for your needs. Always consult your ophthalmologist to decide the most suitable option for your eyes.
